    Discussion about WiFi issues (performance as well as disconnects) comes up repeatedly. Let me try and summarize the multiple remedies that I am aware of:

    Drivers

    Some users have better results with Samsung-provided drivers, others with the latest Intel-provided drivers, and yet others prefer Win8's built-in driver. I prefer the latter on my older Series 7 (with 6230 adapter). But regardless of where you end up, I recommend first cleaning out existing drivers and rolling back to the Win8 built-in driver. Then you can add new drivers from there.

    Note that Win7 does NOT have built-in WiFi drivers for the Intel 6230/6235 adapters, so after this roll-back procedure there will be no WiFi driver installed -- which is OK, we're clean. But before starting the roll-back, download Intel's Driver Only package for Win7 (as described below), and simply install that afterwards.

    Use the following steps to clean out and roll back. This will also remove registry entries from connections created by previous driver entries:

    1) Uninstall any PROset or Samsung provided WiFi drivers using Windows Programs and features.

    2) Reboot (Win8 Restart, not Shutdown).

    3) In Device Manager, right-click the WiFi adapter and select Uninstall; when prompted, check Delete the driver software for this device and click OK.

    4) Still in Device Manager, chose Action (menu) - Scan for hardware changes.

    5) Repeat steps (3) and (4) as long as you still get that Delete the driver software for this device option. That's how you cycle back and delete each of the previous driver versions you have installed. When you do NOT see that option anymore, you're back to the original Win8 driver. Don't uninstall that device (don't click OK).

    6) Reboot.

    You should now be on Win8's built-in driver (or no driver in Win7). If it doesn't work for you (after testing the other remedies in this post) you can update to the latest Samsung-provided driver (using SW Update) or to the latest Intel-provided driver (using Intel Download Center).

    From Intel, I highly recommend the Driver Only version, as opposed to the full PROset version which comes with additional and unnecessary bloat. The file should be called Wireless_x.x.x_Ds64.exe for Win7 and Wireless_x.x.x_De64.exe for Win8 (x.x.x being the version number).

    Note that when installing the Intel Driver Only package, it simply spins an icon for a while, and doesn't display any confirmation. Go to Device Manager to verify that it installed properly. The driver version you see there may not always match the package version (x.x.x).


    Power Profile Settings

    This has always been one of the most important changes to make on Samsung laptops to help with WiFi performance and stability:

    Using the Power Options control panel, Change plan settings then Change advanced power settings. Under Wireless Adapter Settings change the Power Saving Mode to Maximum Performance for both battery and plugged in.

    If this Power Saving Mode is set to anything "slower" than Low Power Saving (such as Medium or Maximum Power Saving) you are likely to experience disconnects.

    Power profile - WiFi.png

    Note that you must make this change for all Power Profiles that you use. That includes Samsung Optimized (default) and Power Saver (used in Silent and Eco Mode). Some people also use High performance or the good old Balanced.

    Personally I use Low Power Saving on battery in my Power Saver profile -- knowing that it will slow my WiFi down when I toggle Silent Mode with Fn-F11. But it saves a little juice, without saving so much that I get disconnects.

    While in there, consider also changing other important power settings as described in this post and this post.


    Adapter Settings

    Check your WiFi Adapter Settings as described in TANWare's post here. In particular, make sure Transmit Power is set to Highest.

    To get there, locate the WiFi adapter in Device Manager, open Properties (right-click or double-click it) and switch to the Advanced tab.

    WiFi Adapter Power settings.png

    Some owners with 6235 adapters have seen improved performance and stability by disabling Wireless-N under Adapter Settings. I have not found this necessary myself, and I hate recommending it because it basically limits WiFi to the old Wireless-G protocol which had a much lower theoretical max transmission speed. This shouldn't be a bottleneck for typical Internet connection speeds, but could limit access speed to disks and and other computers shared on the WLAN. I recommending trying the other remedies first to see if this one is necessary.

    WiFi Adapter settings wireless-N.png

    While in Adapter Settings, you may choose to disable the option Allow the computer to turn off this device to save power on the Power Management tab. Some users have found that this solved their disconnect issues. Personally, I keep this one enabled; after rolling back to Win8's built-in driver (AND as long as my Power Profiles are set as described above) I have not seen any disconnects.

    Router settings

    Many stubborn WiFi problems turn out to be related to the router -- to the understandable surprise of users, because they see the router working with other devices.

    First try power cycling it. But beyond that, try changing to a different router channel that is less crowded. Use the free tool inSSIDer (that was a link) to see how much overlap comes from neighboring networks. Something else that solved issues with my TP-Link router was to enable SSID Broadcast (which I normally like to disable).

    My point here is that there are an infinite number of combinations of routers, settings, devices and environments, so one particular setting may not solve it for everybody.

    For persistent problems, I recommend trying a different router at a friend's house or a coffee shop -- just to see if the problem is really with the laptop or with the router.


    Locating other WiFi discussions in Samsung forum

    WiFi performance has been an ongoing topic on the Samsung forum for a long time. In case you are not aware of it, the following Google syntax is a great way to locate past discussions here: site:notebookreview.com/samsung wifi issues. You will find extensive discussion of this subject in many threads.

    Of course you can use that syntax to locate discussions of other subjects as well :rolleyes:


    Intel 6235 discussion forum

    Finally do note that the Intel 6235 has known connectivity issues as discussed in this Intel forum.


    I hope some of this helps. I'll add to (or update) this post with any new information I see.

    Edit 4-Aug-2013: Added disabling Wireless-N as possible remedy

    Update 16-Nov-2013: Intel has released a significantly updated WiFi driver version 16.6.0. See John's post here for details.

    Update 1-Dec-2014: Updated link to Intel Download Center above.

    Hi dannemand. Thanks for replying to my previous post in the owners lounge thread. I actually tried all of the solutions mentioned above prior to posting but unfortunately none seemed to help. I did see you mentioned something about disabling bluetooth in one of the threads you linked to so ill try that and see how it goes. I havent seen anyone else with the problem related to GPU use though.

    I noticed that you mentioned the issue was triggered by GPU, and admittedly I don't know what that could be. Maybe it really is a power issue as you suggested there, but I haven't heard others mention it either. I just wanted to make sure you had tried the other remedies as well, that's why I referred you to this thread. Clearly you already did :eek:

    You're right, I used to keep Bluetooth AMP disabled in my Adapter Settings. That was when I used Win7 where Easy Settings would let me power off the BT adapter. The options is still there in Win8 Adapter Settings, you can definitely try that and see if it makes a difference.

    Here's a test you could try: What if you run a 3D benchmark or some other 3D app -- but NOT a game that uses network. Then run speedtest.net at the same time. I am curious if the issue could be the actual game and its network access rather than the WiFi adapter.

    Something else playing into your suggestion about power maxing out: Are you using the High Performance power profile? I know many gamers do (hey, they want high performance). The problem is it locks the CPU at 100% (and thus max power consumption) not allowing it to rest even when the GPU is doing most of the heavy lifting. I wonder if that could leave too little power for the WiFi.

    I thought for a second that it might just be generally poor wireless performance because it stopped working when on low settings too. But now its back to the way it was before. I've changed the bluetooth settings but still no luck. I have been using high performance profile but having looked at my power settings that still lets the cpu usage fall as low as 5%. Ran speedtest as you suggested, once with skyrim (single player only 3d game) running and once without. Without it I got a ping of 49ms, download speed of 6.5Mbps and upload speed of 0.84Mbps. When I ran it with skyrim open it failed completely showing a ping test error. Im considering just returning the laptop as there's clearly something strange wrong that I doubt ill manage to fix

    Thanks.

    If Minimum processor state is 5%, that's good. I believe default in the High Performance profile is 5% on battery and 100% when plugged in. If the problem is really power maxing out (and we don't know) that could have been a reason. But you already changed that, so it isn't.

    While we're at it: You DID update the Wireless Adapter Settings in the High Performance power profile to Max Performance, both on battery and plugged in, right? I am sorry to even ask, just making sure :rolleyes:

    Otherwise I agree this sounds odd, I haven't heard it from others (at least that I remember). I would go for swap if you can.

    Did you try to set CPU maximum state at 99% instead of 100%? This should prevent TurboBoost from being activated, thus reducing power consumption

    Sorry for the delayed reply. I was away for a few days and then had guests staying so didn't get much time to test. I tried the power settings you suggested but it seemed to make no difference. Having spent the last couple of days trying out different combinations of graphics and wireless drivers I've found that I get the best performance using the samsung provided gpu drivers and the latest intel wireless wifi driver (16.1.1 on the intel download page but reading 15.10 in driver details once installed).

    Having done some testing on a friends router I have also discovered that mine definitely needs replacing as the signal strength is incredibly weak in comparison. There were some minor connection issues when testing on my friend's router, however he claims that he does frequently get ping spikes on his connection and the issues were so minor with the gpu in use that it was very difficult to determine whether using the integrated gpu made any real difference. Having also tested my own router with an older laptop that previously worked well, I noticed that it too was now quite unreliable at the same range. Due to the older laptop's (First gen HP envy 15) chronic overheating problems, I wouldn't be too confident in the health of its wireless card and so am not sure it makes a great comparison, but it was the only other laptop available to me that didn't use integrated graphics and hence could test any games.

    The fact remains however, that on my own own (apparently very poor) connection turning off the dedicated gpu makes a very noticeable difference to connection quality, even with the better drivers, and I can't figure out why.

    I have contacted the retailer who sold the laptop and they said that a replacement isn't possible due to lack of stock but have offered me a refund up to the end of the month. As I got the laptop at an excellent price a replacement would have been ideal (and I could have worked out was it an issue common to this model or just this laptop), but I'll test a few more routers over the next day or two and let you know the results before deciding whether or go for a refund or just get a half decent router, as the impact may be very minor and only apparent on a very tenuous connection.

    @PenguinPlop: Thanks a lot for that update. I love how thoroughly you have approached this. Also, your findings are a reminder how much difference routers can make.

    It does indeed sound like there is some correlation between your GPU and your WiFi. That's still puzzling to me. In addition to the power draw (which you mentioned originally) I wonder if the GPU may actually create some radio interference.

    Did you try different channels? 20 vs 40MHz Channel widths? 2.4GHz vs 5GHz? Disabling Bluetooth AMP and/or disabling BT entirely?

    You probably tried those already, I just wanna make sure :eek:

    Roll back to original Windows 8 driver works great for me and always has - worried Windows 8.1 will have a new driver with it though, removing the old working one.

    I am troubleshooting this problem on my Samsung Series 9 Ultrabook (NP900X4C-A01US) right now... I've had the sporadic drops for ages, but hadn't had time to explore/troubleshoot. Found this thread in the process. There's an amazing thread at Sporadic but recurring connection dropouts on an Intel 6235 wireless adapter -- 49 pages of people complaining about the identical problem on multiple laptops equipped with Intel 6235s. The one additional "take away" from that thread that isn't in your fantastic post is to set a SPECIFIC CHANNEL for your ROUTER'S N NETWORK. That makes sense for several reasons. Worth trying. Will let you know what I find out.

    Hello danholme, welcome to NBR. And thank you for sharing your findings.

    I absolutely agree: Checking their router channel (using inSSIDer or similar) -- and changing it if there is interference -- is something everybody should do if they have WiFi performance problems. It's actually on the list of items in the OP, but now that I re-read it, I agree that entire section should be spelled out in more detail.

    There are a few other changes and additions I want to make in the post; hopefully I'll get to it later this week. Thanks again!

    I agree, I personally prefer Win8's built-in driver as well. Although some members seem to have found better results either with Samsung-provided drivers (original or latest) or with Intel's latest.

    Just checking: Did you feel this was not well reflected in the OP? Or did you intend to confirm that Win8's driver was your preferred one as well?

    Thank you either way!

    I've got the latest intel driver installed for the wifi (Version 15.10.0.11) but thought that the bluetooth driver for the 6235 was integrated into it. In SW Update there is the option to download a Bluetooth Driver that is 155mb in size (that I suspect contains the wifi driver as well that I uninstalled as per instructions in this thread - in addition to Intel Widi and bluetooth drivers). Does that Bluetooth Driver in SW Update just reinstall the old Intel Wifi driver that is known to cause problems or is that really 155mb of bluetooth drivers? By the way, in the Windows 8 wireless panel, it is possible to disable wifi but not bluetooth so the full functionality/compatibility is being limited by the MS bluetooth stack I suspect. Thanks!

    EDIT: Answered my own question. ;) I used the download only option for the bluetooth driver and ran the setup for the 64bit bluetooth drivers and all it installed was bluetooth (which can now be enabled and disabled from PC Settings in Windows 8). All is good!

    Hi Shrink,

    Yes, that driver from SW Update is just 155MB of pure Bluetooth :D

    Unless you need some of the additional features it provides, I recommend just staying with Win8's built-in Bluetooth driver. However, as you found, there is one desirable feature in that 155MB package: It enables toggling Bluetooth on/off, in Settings as well as on Win8's Charms-Settings-PC Settings-Wireless screen.

    However, even though I prefer prefer being able to disable Bluetooth, I still don't find that driver worth the bloat, because apparently that toggle function does nothing more than disabling/enabling the Bluetooth device in Device Manager. It's not like in Win7, where disabling Bluetooth in Easy Settings will completely power off the Bluetooth module.

    I recently had to refresh my memory about that, when I wrote this post.

    For this reason, I am not sure if turning off Bluetooth will help WiFi performance as much in Win8 as it seemed to do in Win7. Still, anybody who doesn't use Bluetooth should disable it, both in order to (potentially) improve WiFi performance, but also for security. In Win7 Easy Settings will do it; in Win8 either Settings, Charms-Settings-PC Settings-Wireless -- or simply disabling the device in Device Manager.

    As for WiDi, that's yet another big fat driver, not included in any of these.

    I am using a Motorola S11 Flex HD Bluetooth headset. My problem is, every time I press play on a video, or really anything that involves audio, in the headset I hear "Device 1 disconnected, Headset not connected, Device 1 Connected". After that, it plays fine, but if I don't have any audio going on after about 5 or 10 minutes, it will once again say that message and then play the audio.

    Is this a bluetooth driver problem? Has anyone else experienced this? Is there anything I can do?

    Thanks.

    Hey Steve,

    Sorry, I DID see your post when you first made it, and meant to come back to it -- then forgot all about it.

    I am afraid I don't have an answer for you. I don't even use Bluetooth much with my own PC.

    I would re-post in the Owners Lounge thread for your model. You've waited long enough and can go ahead and do that. Make sure you mention your exact model number in the post.

    Check John's Sticky thread (below) for links to the most common Owners Lounge threads.

    Has anyone had trouble updating the Intel Centrino Advanced-N 6235 network adapter? I have a Samsung Ativ Book Series 6 (NP 680ZE-X01US) and I downloaded the latest drivers (v. 16.1.5) for my OS (Windows 8 64-bit). Yet, when I run the program, I briefly see an animation showing that it's being installed and then there's no message to confirm if it's been updated. From reading this thread that's normal, but when I check Device Manager, it's still using the drivers from August, not the latest version released on 9/11/2013. Anyone know a way around this or am I just worrying about nothing?

    The update probably worked. It can take several weeks for testing between an updated driver being prepared and actually released as part of an installer package.

    I have also installed the 16.1.5 package and the driver is reported as 15.10.3.2 dated 22 August 13.

    If there is any correlation between CPU or GPU and Wi-Fi there's a design flaw in the notebook itself and more specifically in the routing of antennas within the main unit.
    Antennas should not be routed anywhere near CPU, GPU or RAM as these are sources of interference.
    For me, it's hard to tell if its the case with notebooks mentioned here as I didn't see inside layouts. Still it can be the case with bad design- see this article for more details.

    Intel blames wireless issues on notebook manufacturers (bad design) but at the same time they claim not to be able to replicate the issue. It's possible that there is a problem with the design of a 6230/6235 though- the issue is too widespread (happens in different notebooks) and at the same unique to this particular card (other cards work fine). At the same time there are issues with different cards that may be blamed on notebook design. Mix of the two makes it very hard to pinpoint the issue without an RF lab at your disposal.

    There's also a misconception about Intel's supposedly good driver support. They do provide regular updates on their website- that's it- that doesn't make their drivers good.
    It got to the point where there was a sticky warning about issues with Intel drivers at the top of DD-WRT forum for quite a while. The reason I'm pointing it out- with Intel new driver doesn't actually mean better driver. Multiple users have reported issues with 6230/6235 vanish with certain drivers only to re-appear after an update- so if any of you guys happen to stumble upon a less problematic driver- stick to it. Intel admitted that they cannot replicate the issue so they have apparently fixed it by chance and then broke it again also by chance.

    That could be a factor in the poor WiFi signal strength - the 2012 Series 7 and 9 notebooks (and maybe some of the 2013 models) have the antennae along the back edge of the chassis and quite close to the CPU etc. They are the orange parts in this photo:

    66193.jpg

    However, frequent dropped connections when the signal strength is OK is a driver issue.

    I had that particular issue early on (disconnects despite strong signal), and the two settings I found that most affected it, were:

    1) Wireless Adapter Settings-Power Saving Mode in the power profile (ALL the profiles being used): When this was set to Medium or Maximum Power Saving, I would get disconnects; when set to Low Power Saving or Maximum Performance I would stay connected. This was true regardless of driver version, although more pronounced on certain Intel drivers.

    2) Combinations of different routers and router settings. On my TP-Link WDR3600, I found I had to enable SSID broadcasting (which I otherwise like to disable); other routers may have other quirks. Of course channel selection is critical -- that goes without saying; or maybe it goes WITH saying and frequent repeating ;)

    @downloads: I think you could be spot on that antenna placement may be the reason why some models see GPU or CPU activity affect WiFi performance. I am usually understanding of the compromises that Samsung had to make in antenna placement vs chassis materials and design in these elegant models. But this choice would be a real oversight if it is the case.

    Dear all,

    yesterday my x4c started to have a strange behavior when I reboot it. The wifi connection takes more than 10 min to establish.
    I followed the procedure described at the initial of this post, but it did not solve the problem.
    After being connected, I have no problems at all. Even when I put the PC at sleep (hibernate), the connection is fast. The issue is after a reboot.

    Have you seen similar behavior?

    Hi Sonic,

    I DID see that problem a few times when I was running Win7, maybe not 10 mins, but a considerable delay. It was caused by Easy Settings delaying the loading of some system tasks, in order to make it appear that the machine boots faster (the-called Boot Optimization / Samsung Fast Boot Mode feature described in the Easy Settings thread).

    If you are running Win7, I recommend uninstalling and re-installing Easy Settings (reboots in between). Make sure you get the latest version of Easy Settings (see that thread linked above) as it can make a big difference.

    If your model has ExpressCache, I also recommend AFTER you have completed these installation steps, to use CCleaner (google it) and Disk Cleanup to clean out temp files, then defrag the system drive, and finally run BOOTOPT.BAT in the ExpressCache programs folder ("C:\Program Files\Condusiv Technologies\ExpressCache" or "C:\Program Files\Diskeeper Corporation\ExpressCache" depending on version). You have to do it in that order. ExpressCache can sometimes interact with Easy Settings in a bad way that exacerbates the delay effect. But when it works right, it speeds everything up.

    Additional steps you can take are to disable the WLANStartup task (making sure that WiFi still comes on after reboot after you did) and defeating the Boot Optimization feature altogether. These are described as part of the extreme optimization steps in the latencies thread (WLANStartup in the opening post and Boot Optimization here).

    All of this assumes that you are using Win7 (ie Easy Settings).

    If you are using Win8 (ie Settings, which doesn't have these issues) I don't know what could cause this delay. You probably already re-installed (or rolled back) WiFi drivers. You could try and re-install the latest Settings, but that's all I can think of.

    For now I founded a good solution to pass from the DHCP to static IP. I used I static DNS too (in particolar the google one 8.8.8.8). My modem is set with DHCP but I setted my laptop with a static IP of the same class (192.168.1.xxx) and for now the disconnection problems seems to disappear.
    Can some one try it and confirm that is'n only a coincidence?

    Got it. In that case there is a good chance those fixes I mentioned will help.

    Thank you for posting this suggestion. It had not occurred to me that DHCP provided IP or DNS might be the cause of these connection problems. I currently don't have any problems myself, but many others still do. Hopefully we can get some feedback on that.

    Independent of the WiFi issues, using Google's DNS servers (Preferred=8.8.8.8 and Alternate=8.8.4.4) has been known to improve performance compared to using the automatic DNS servers provided by ISPs. It's is a common suggestion among users of Netflix streaming devices.

    Hi guys. I have Samsung Series 900X Notebook 13.3" I also suffered the same frustrating wifi drops until I went into my "wireless network properties". Right click on your wifi connection. Click " View connection properties". Click "CONNECTIONS" tab. Check boxes for both "Connect automatically" and "Connect even if the network is not broadcasting its name (SSID)". My problem was solved. I hope this will help you too. Good Luck!

    Thank you for the information. I have been having the typical connection loss problems. However, I have had another specific wifi issue that I haven't seen mentioned here.

    On one specific WPA2-Enterprise network, if my Series 7 Ultra goes to sleep mode, it will often be unable to reconnect to the network when it wakes up. Strangely, it is sometimes able to connect to other networks in this state, but not always. The issue goes away on reboot.

    This issue is present with both Win8 default and the PROset drivers.

    Hi JoeTaco,

    The two settings I am aware of that do most to help unintended disconnects are the Power Profile and Power Management Adapter settings, both described in the opening post.

    But since the problem you describe is one of re-connecting after resume, maybe it's something else. Definitely try deleting (Forgetting) that particular network and re-connecting to it -- if you haven't already.

    When trying different drivers, did you delete the device and "roll back" as described? I ask because I remember having connection problems that resolved after clearing out that connection in Registry and creating a new one. This was particularly a problem in Win7 with Easy Settings (as discussed in the original latencies thread). If you have installed Easy Settings (which is for Win7), you should get rid of it and install Settings instead (which is for Win8).

    If none of that applies to you or solves the problem, I'd say it's most likely one of those issues between certain routers (and their settings) and your WiFI adapter and/or drivers. Other than tweaking channels or settings on that router (which I understand is probably not an option in this case) I don't have any suggestions.

    This is the exact issue I have with my 6235 now. Did you ever fix it? Thanks.

    Intel has released driver version 16.6.0 dated 14th November 2013. There are Windows 7, Windows 8 and Windows 8.1 versions (that they need separate Win 8 and Win 8.1 versions highlights that 8.1 is more than a service pack).

    This might fix some more WiFi issues.

    John

    Update: Weak signal performance is much improved for my X4C which previously struggled on my standard test at the far end of the house from the router.

    Thanks a lot, John. It sounds like this could be an important one, particularly for those on Win 8.1 who no longer have the original Win8 driver.

    I added a brief update in the opening post, including a link to your post.

    Same here, updated to 16.6.0 using my Samsung 740u3e with builtin Centrino 6235 chip and I'm not having any issues so far.

    I've got 15.10.4.2 dated 23 September. That's about a month newer than my previous driver.

    I've noticed before that the version number of the driver is not the same as the version number of the installation package. I think this reflects the installer doing more than just load a driver. There's other background configuration and maybe Bluetooth and Intel's PROSet software depending on the installer type.

    I would add that SW Update lists a full set of Windows 7 drivers and software for that model.

    If SW Update is not installed then go to a Samsung support site. It is one of the few remaining downloadable programs (SW Update downloads the rest).

    So I followed the guide here to the letter. Uninstalled any proset driver rebooted then cleaned the various driver history from device manager intel advanced N 6235 until all was left was the windows driver.

    Downloaded the driver only package from intel download manager and tried to install that driver package. However once I double click the file nothing happens and just after 2-3 seconds this table pops up Capture.PNG and after I type OK nothing seems to happen anymore. I checked in the device manager and the driver these is still the one from windows 8.

    Any idea as to what is going on? or what I did wrong or what should I do ?

    Thanks

    What is the name of the installer program are you running?

    The driver only installer is called Wireless_16.6.0_De64.exe (see this Intel page).

    Hi fireregister,

    To follow up on your pm and John's post: Just run that EXE directly (don't extract it). It will spin an icon for a while, but but not display any other confirmation.

    I didn't extracted. I run it and nothing shows up on the screen, after a while a pop up comes out (the one in the screenshot I posted above). I tried leaving that pop up there and doesnt dissappear for a long of time, after I click OK nothing happens and when I check device manager no drivers have been installed. I also tried clicking OK as soon as that pop up comes out and still the result is the same. In all of the cases I've left either the pop up or laptop as it is for like 15-20mins. I dont get any spinning icon :confused:

    Hi John

    The installer is called wireless_16.6.0_De64.exe so basically the same you said and the same as the one recommended

    Something strange going on here. the Installer doesn't give much sign of activity apart from an animated icon but we've not had other reports of your problem.

    Did you try right-clinking and selecting Run As Administrator in case something is blocking part of the installation?

    Hi John,

    Thanks for your feedback. However I've done that as well, doesn't change a thing..

    Edit: Should I maybe disconnect the wifi while trying to install?

    Yes, something is definitely not right. This is not what I've seen, and not what others have reported either. Of course that's little help to you :eek:

    All I can think of is to try downloading again (if you haven'y already) in case the first download got corrupted. That happens more often than people realize.

    You could also try and delete the WiFi adapter in device manager (like you did when you rolled back), reboot and let it re-detect the device. It should install the basic Win8 driver anew. Then you can try installing wireless_16.6.0_De64.exe again.

    But since something is messed up there, who knows what will happen: If you have it working alright with the current driver, maybe you're better off leaving it at that.
