WiFi Remedies for Samsung Laptops

So basically downloaded again (have trying that a few times) and also tried uninstalling the wifi adapter and rebooting still having the same results and the same thing as before. So basically gonna give up now

 

Are you running the installer from a command prompt? Not that is should make a difference, but just run it directly from a file explorer window.

Beyond that, I am afraid I don't know what could be causing this. Some Samsung models have non-Intel WiFi adapters (such as Broadcom) but you already confirmed that you have Intel 6235, so that's not the reason. Something is wrong in that installation.

The built-in Windows 8 driver is not a bad place to end up, though. In fact I still use that one because it had better performance and stability than the Intel drivers. I haven't tried Intel 16.6 though, which John and others found to work great.

 

I'd have to say that having this laptop for 6 or so months, I am almost completely dissapointed with it.



^^^ This is absurd!

I have a 105Mbps home Internet connection and I have a 5 year old laptop right next to this one that gets about 40Mbps.

Is there no fix or is there anyway to replace the existing nic?

Currently I have the Intel Centrino Advanced-N 6235 nic with 15.10.3.2 Driver.

Edit, just upgraded to 15.10.4.2 driver:

Still worthless.

 

@Steven,

Did you make the tweaks described in the first post of this thread? In addition to selecting the right driver, the power settings tweaks are critical for performance.

Otherwise, if you already tried all that, I would personally contact Samsung to have it fixed. What you're seeing is not normal - even for Samsung laptops with 6235 adapter.

 

Which model Samsung and what signal strength are you getting when near the router? Use InSSIDer to see the strength and channel. -40dB would be a reasonable value close to the router. If you are getting a lot weaker (eg -70dB) then this would suggest that either the antennae are defective or one / both are not properly plugged in to the WiFi card (they are fiddly littel plugs).

@John

2 feet from my router my signal is at -30dB about 30 feet away where I normally sit the signal is about -60dB (with almost direct LOS).

My router is a DIR 655 and is only 2.4Ghz, I wonder if that plays a part? I tried all of the drivers and methods, I have my settings tweaked but not so much as a dent in performance. The quality of connection seems to come and go, some times I will get 10Mbps, sometimes as low as <1Mbps. But still makes no since when all the other laptops we have in my house are consistent with at least >30Mbps.

I really don't want to deal with support and I can't afford the time away from my laptop to send it in. Is there no way to change out the nic by myself? I suppose I could open it up and look but instead I'd rather just ask those that have.

Thanks for your responses guys.

 

That signal strength is fine so it's likely to be a driver / configuration problem.

Did you try a complete uninstall of the current driver / Intel ProSet software before installing the newest version which might then do a better job of configuring the settings? If not, that's the next step.

I can't remember if I did the uninstallation first but the latest driver package made a noticeable difference in the longer-range performance of my 6235. You should try a few more software fixes before spending on new hardware (and you might want to consider this type of adaptor - I have one as backup). There are a few other WiFi + Bluetooth cards around. Killer is a name that comes to mind.

So I'm wondering if anyone has any ideas on this. I replaced the 6200 card in my X3B with a 7260. The wifi strength appears to be stronger, but I'm having trouble getting the bluetooth working. This seems to be related to easy settings. If I uninstall easy settings I can get the laptop to recognize the bluetooth adapter and connect a mouse. But with easy settings installed it is as if there is no bluetooth as seen by the system (in device manager). The bluetooth toggle that I had in easy settings with the 6200 has also disappeared. I kind of need both easy settings (for the hotkeys) and bluetooth, maybe I should install another version of "settings"?

 

Which version of Easy Settings are you on?

If you are on V1.something, the installer for Settings V2.0.0.38 includes a Win7 folder which has a V2 Easy Settings. That version of settings is listed in SW Update for NP900X3C-A06UK > Windows 8 (and probably many other places). V2 Easy Settings is probably also in Settings V2.0.0.30 listed for the NP900X3B-A01UK > Win 8.

John

 

Thanks John, I tried the new Settings and the issue remains. With it installed bluetooth on the 7260 is no longer functional (and disappears from the wireless menu). I think it is disabling the (bluetooth) adapter, which is probably the default to save power, but since it is a different card does not recognize and allow me to turn it back on. I can't remember for sure, but there is no way to get the keyboard functionality provided by settings without the application in W7/8, correct? I probably also need it for lid operation as I now see there's a toggle which may have been messing me up in W8. Why does Samsung think they know how to design software? Just a bunch of bloat and kludges.

 

What a true statement!

I think your best bet is the opposite: To go back to an early version 1.x of Easy Settings, then sideload just the Fn-keys module (EasyDisplayMgr=dmhkcore.exe), as described in the old Latencies thread. Unfortunately that hack is not possible in newer 2.x versions of Easy Settings. You will lose some other Easy Settings features (although some can be loaded individually similar to EasyDiplayMgr) but at least you will avoid it interfering with Windows' built-in support for your Bluetooth.

Are you using Win7 or Win8? As you know, Easy Settings is for Win7, whereas Settings is for Win8. But if you only sideload EasyDisplayMgr, I suppose that can work in Win8 as well.

Edit: If you lookup my model NP700Z3A-S03US in SW Update, it has Easy Settings 1.1.0.28 listed under Win7 software.

 

Thanks Dannemand, I did the sideload trick by adding a shortcut to dmhkcore in startup, could not get a scheduled task to work. Anyway, now I have function keys and wifi+bluetooth on the 7260! The connection appears to be much more stable as I'm able to dlna HDTV without interruption/breakup so far, the 6230 had a lot of trouble with it. Do you know if there is a module for the "Samsung Fast Start" (not Fast Boot) feature, this appears to contain the lid open action, that I really hate to lose. I can get it back temporarily, if I open the controlcenter module and toggle the setting, but it doesn't persist across restarts. I am on W7, back using the 1x Settings, since I couldn't tell whether the side load trick worked on 2x settings (I guess it doesn't).

 

Note: The rest of this discussion about Fn-keys, Fast Start and other [Easy] Settings related topics was moved to the Settings/Easy Settings thread, starting here.

 

Hey, does anyone know if the limited connection issue in Win8.1 has been fixed? Ive tried pretty much everything in this thread, including installing the newest 16.7 drivers from Intels website (which for some reason is still said to be 15.10.5.1, dated 31.10.2013 in the device manager), but nothing seems to solve this problem for me

I should add that my laptop did not face any of these issues before I went home for Christmas - i never had connectivity issues using my university wifi or the wifi in my flat. I did however install the Intel wifi hotspot thingy after I came home (dunno why it never prompted me to install it before, maybe it came with an update?) and that seemed to be the catalyst for the problems :/

 

I know there have been dozens of threads about the issues with wifi in the Series 7 notebooks, but I didn't want to resurrect one of them for my issue, especially since the biggest thread about replacing the wifi card is actually using the card that I HAVE in my Samsung. Let me explain a bit.

I have a Samsung Series 7 Chronos 700Z7C, which contains a Intel Centrino Advanced-N 6235 wifi card. This was supposed to be the card that fixed people's issues with Series 7 broadcom cards, but I can guarantee I still have as many issues as could possibly occur with one laptop's wifi. Right now, sitting a room away from the router, I am pulling the proper speeds I should be. Unfortunately for my sanity, I spend most of my time upstairs from the router, and I have had issues getting a decent speed up there since I bought this laptop. For a while, a USB wifi adapter fixed the issue, though it was just a temporary fix as I figured I would be replacing the wifi chip later on. However, I recently had changes made to my internet and now I can usually barely pull a 0.50 MBp/s upstairs at BEST, which means it's impossible for me to do anything I need to do. Pages won't load. Needless to say, it's frustrating.

I re-visited the threads on this forum and read up on how to replace the wifi chip, only to notice - as I was getting all ready to order a card and do the swap - that the card everyone was referring to was the card that I have inside of this machine. Clearly, it's not working. I didn't want to replace the card with the same kind just in case it doesn't solve the issue.

So my question is, knowing that the 6235 card is somewhat "old" at this point, what are my best options? Is there a new card that will solve the issue and doesn't have the intermittent errors that the 6235 has? Or should I assume that my existing 6235 card itself is faulty, and replace it with a new 6235 (that seems like a waste of time to me since I have seen other threads with many people having issues with the 6235 card, but I should ask anyway)?

I would honestly appreciate any help and any ideas on how to solve or improve this issue at this point. Getting a stronger USB wifi adapter isn't really an option for me, because I need the dinky two whole USB ports that I have, and having a huge adapter sticking out from the side at all times is really not a solution to me.

 

Hi delightfulday, welcome to the Samsung forum. And what a delight full username

I took the liberty of moving your post here, where we are trying to gather the most up-to-date WiFi remedies for Samsung laptops. I know you said that you have looked in other WiFi related threads already, but you didn't mention specifically what you had tried and which threads.

Please make sure you try the MULTIPLE remedies described in the opening post of this thread as well as the subsequent posts by other members. It's only a few pages to read.

The Intel 6235 is generally considered the most troublesome WiFi adapter in recent Samsung laptops (although I had a model with Broadcom which was truly terrible). Intel's latest driver updates have improved the situation for many. But as you will see in the opening post, getting the best driver for your laptop is only one of multiple remedies.

Let us know how it goes.

 

I would emphasise that the newest driver is direct from Intel, not the newest being offered by Samsung for your notebook.

Hi, I might be joining this thread too late. But I have a Samsung notebook with a Intel Wireless card (Centrino Wireless-N 130), and I've been experiencing troubles with WiFi almost since I have it.
I just want to share my solution for the wifi to work. This is not definitive, but it works really well in my notebook. I noted that just by turning off Bluethoot in the wireless settings, WiFi starts to work normally. I have to do this every time I reboot my computer, and, of course, I don´t use Bluetooth frequently. In that case, I only have to turn it on.
I haven´t read the full thread (and I'm not going to ), so my solution may have been already posted. I hope it can help anybody with the same trouble.

 

Hi mallama, welcome to NBR. And thank you for posting that.

It has been reported a few times that disabling Bluetooth can help, but I don't think as categorically as what you described here. And in any case is it worth mentioning again.

I am puzzled why you have to disable it after every reboot: In Win7, Easy Settings can actually save the Bluetooth on/off state and restore it after reboot. In Win8, one has to use the Charms-Settings-PC Settings menu to disable Bluetooth (and that toggle is only avaiable if the bloated Samsung Bluetooth driver is installed; it doesn't work with Windows' built-in Bluetooth driver, which I otherwise prefer). But that Win8 toggle merely disables/enables the Bluetooth adapter in Device Manager, which one can do manually. In any case does it persist after reboot.

Which model and Windows version do you use? And which Bluetooth driver (from Samsung or Windows or Intel)?

 

Problem with the Wireless Card 6235 I can see this guy in in the device manager but not in CMD.
My System W8.1, x64, Card Intel 6235N, Samsung 870Z
Last week i got an error with the Network Bridge from VMWare (Blue Screen in W8)
So I deinstalled the stuff.
-->Then I got problems with the graphic cards so reinstalled both ATI (8xxx) and HD4000 (now working)
-->Then I got Ethernet problems reinstalled (now working)

-->Then a big shock I see only the wireless sign with the white cross on a red circle background.

So I looked in the device manager (no problems, he says but windows problem solver says could be a driver problem) reinstalled 3 different versions off Wi-Fi.
Nothing, the sign is still there.
Now I deinstalled the whole drivers and push at "find hardware" in Windows, he found the card and reinstalled with the Windows drivers by itself. Problem still exists.
Then I checked this in the terminal CMD and next shock no hardware was found. I checked with a hardware software AIDA, it also doesn't find the card.

In the last days I bicycle a lot and the side back shocks with the notebook could be to hard, but something strange in my mind. I thought the N6235 supports the Bluetooth and wife on board am I right?
Because the Bluetooth works without any problems.
So would could this be?

Hope you can help me.

A workers notebook is rubbish if it has no access to the Wi-Fi internet.

Best regards,

Hello aewe304, welcome to NBR.

It sounds like this is much more than just a WiFi performance issues. If you had VMWare installed and uninstalled, it may have left some dirt behind. VMWare overloads a number of different drivers (network, graphics, mouse, keyboard etc) in order to serve the guest VM. I even think some VMWare versions install Apple Bonjour, which can cause an awful mess on a Windows system.

In your situation I would simply roll back to a known backup or restore point, instead of spending more time on it. Or perform a factory restore if you still have Recovery. Then move forward from there, making backups/restore points along the way.

 

Hi yes, but I cannot really reinstall the whole holy machine, so many programms run on it for the work.

Hope you can help me. I tried now.

-USB-Tethering over my Cellphone. Works perfekt.

- Wifi USB Stick. Same problem as with the internal Wifi Card, he gets to know in the device maanger that it is there and than I see it in the Networksettings as a Wifi Ntwork, but I cannot connect to anything and in CMD the device is also ot listed.

Best regard

 

All I can suggest is you try the thorough driver cleanout procedure (steps 1-6) described in the opening post (#1) of this thread: Uninstall any existing WiFi drivers using Programs and Features (PROset, Samsung, USB WiFi, USB tethering, everything) then keep deleting the corresponding devices in Device Manager and their drivers until you are back to scratch. You need to connect those USB WiFi devices you just tried in order to perform the cleanup. Then reboot and let Win8.1 install its own drivers. Accept any WiFi driver updates from Windows Update.

Please follow those steps 1-6 EXACTLY. That is a very thorough cleanout.

If you cannot get WiFi working this way, it is messed up beyond repair, and you have no choice but to factory restore. If you were still on Win8, I would say you can try Windows' Refresh feature, but not after updating to Win8.1.
