Dell Xps 13 2015 wifi problems?

Hey guys is there anything I have to do before I connect to my wifi Network?

Works perfectly fine on my other laptop and cell phone but I keep getting "can't connect to network" on the xps?

Any help would be appreciated thanks.

 

I did everything I could on my end to troubleshoot the problem. It is not related to my network, it won't connect to any other.

I spoke to Dell for a while and they're sending a technician out to replace the network card.

Just my luck.

 

Not great, I have the Intel Wifi and it's given me no trouble at all both at home and work using different routers and setup's. Hope you get yours sorted.

 

Fingers crossed a replacement card will sort you out, I haven't had those problems with my XPS 13 which has connected fine to few different wireless network types. I did find Windows 8 was sometimes a bit iffy with wireless networking but it would usually connect fine first but then randomly drop the connection for no reason.

 

On my machine (I7 5500 QHD, Intel 7265AC) WiFi won't work 1 out of 3 times after waking from sleep. 2 / 3 times switching into flight mode and back solves the problem. Sometimes I even have to disable/reenable the network adapter in the device manager (the toggle in the network charms bar won't work).

Anybody else experiencing this behaviour?

 

I experienced a similar issue where once the machine had gone to sleep (for a decent period of time), on reawakening it didn't show any wireless connections to connect to. Meant I had to restart my machine each time which was annoying.

Spoke to Dell support who suggested deselecting the option to allow the power to the wifi device to be turned off when sleeping which fixed the issue. Obviously I think this will affect how long the battery will last in sleep mode but Dell claimed otherwise.

 

I have the DW1560 card in mine and noticed that when I first booted up (Dell image) it would not see my 5ghz network. I did a clean install and during setup it saw and connected to my 5ghz network with the Win8 drivers. However, when I installed the DW1560 Wifi+BT drivers, it no longer sees my 5ghz network. Otherwise, my WiFi works just fine. I'm going to see if I can uninstall just the WiFi device and then try to use the Windows drivers w/o effecting the BT.

 

Ok, so when I look at the Device Manager with the Dell driver installed the device shows as a Dell Wireless 1560ac and 5ghz networks are NOT detected.

When I uninstalled just the WiFi device (check box to uninstall driver software), the bluetooth device remains and Windows installs the drivers it has for the device. It now shows as a Broadcom Wireless 1560ac and it now shows 5ghz networks.

 

Yes - from what I could tell the Dell DW 1560 is actually a Broadcom manufactured device

 

I knew that going in, but was letting people know an easy way to identify the Dell driver vs. the Windows one.

 

Neither the Windows driver (6.30.223.102), nor the DELL driver (6.30.223.227) will work without issues.

You will need the Broadcom driver 6.30.223.245.

You can get it from the HP website (sp70360.exe) on:

http://h20564.www2.hp.com/hpsc/swd/public/detail?swItemId=ob_143095_1#tab5


Once you extract it, you will need to point windows to manually install the Broadcom driver for the “BCM4352Z 802.11ac 2x2 WiFi Adapter” and this will resolve the problem.

 

Dell should provide an option for Intel 7265...

 

There are 2 manufacturers for the WLAN modules for the DELL XPS13 9343 model.
One is Intel, while the other is Broadcom (DW1560).
My reply was based on the Broadcom (DW1560). For the 7265, if the DELL driver is outdated, you can always use the latest driver directly from the Intel website.

 

I went from the SSID not even showing to 866Mbps. Very grateful for the solution

 

I've got the Broadcom "Dell 1560" AC Wireless adapter and the Dell driver wasn't always picking up my 5ghz network. I ended up uninstalling the driver and using the Windows 8.1-provided driver. I'm also not really happy with the performance. I'm tempted to buy an Intel 7265 to replace it...

 

Has anyone figured out how to solve it on Windows 10? It seems to happen even with the 7.35.295.0 Broadcom Windows 10 driver on Dell's site. I found the 7.35.308.0 driver in a few places, including from Windows Update though which I might try on the computer in question (it doesn't belong to me).

EDIT: I saw a mention on reddit that simply downgrading to the older driver might fix the issue on Windows 10 as well. Now I have two things to try which gives me some hope.

 

I'd try the driver link above, posted by Panos, from HP. That worked for me, as shown in my screenshots in this thread. When I check the driver in Device Manager now, the current driver appears to be the 7.35.295.0 driver dated 2015-07-30:



So, as I can't remember doing any manual WLAN driver installs since the HP one, I'd suggest you download and install the one from HP (which definitely worked for me) and then you should be able to update it via Windows Update.

My Wi-Fi still picks up 802.11ac, and still has very fast throughput on my home network (e.g. 50+MB/s aka 400+ Mbps from my NAS under heavy use, and near 1GbE wire-speed when my NAS has light load)

 

So basically Windows Update updated you to a driver that in my case shows the same issues but for you suddenly works fine? You'd think then that using those drivers from Dell would work just as well as the only difference should be the a modified name in the inf file. I'd be a little weary of updating the drivers after I've downgraded if I notice that the old drivers fix the issue. I might just use that microsoft tool to hide the updated drivers.

Thanks for the updated information.

 

Just to clarify, since I installed the HP driver, my Wi-Fi has been perfect, with the HP one linked in this thread, and any automatically updated driver since. So the suddenly started working correctly behaviour started immediately after installing the HP driver.

 

I went over to my parent's house after work to try this out. I figured I'd uninstall the Dell driver from device manager (and also clearing it out of Windows driver cache with pnputil) and to my surprise it then it reinstalled it with a driver in the same generation as the driver sourced from HP (slightly newer but in the 6.30.2* range). It seems to act much better with that driver (similarly to the one you suggested I imagine) but we'll just have to wait and see. After all, the issue was sort of intermittent. I surely hope it works now though. If not, I'll try the exact driver you used.

EDIT: So far so good. I'm really curious what this driver does differently and even more curious why it would fix later drivers as well (but it would explain why Broadcom keeps pumping out "broken" Windows 10 drivers).

 

I just got a brand new Dell XPS 13 9350-4007SLV and it done the same thing to me. Seemed fine closing the lid and reopening short periods of time, but overnight required a reboot to gain WiFi again. It just showed no networks available.

• Intel Core i5-6200U
• 8GB memory/256GB SSD

 

I've only just started experiencing these wifi drop-out issues.
My CPU hits 100% at the same time as the drop-out.

My only success (apart from reboot) is to switch into Aeroplane mode for 10 seconds then switch it back off. Reconnect wifi.

I'm hooking up to 5GHz BTW (in case that matters)
