XPS 13 9310 WiFi randomly shuts down (AX500-DBS)

@evolevol 

I had same issue, ran Dell update earlier today, it failed for whatever reason, post restart, got same wrong driver number error.  Called support and Nandini helped me out and now its fine.  The steps we took, which in end were to reset BIOS defaults were:

- Reboot, hit F12 while Dell logo, to get to EPS Safe Screen for Hardware scan.  This was to check for device/hardware issues.
- Ran diagnostics, all my tests past, click exit.
- Do a full restart, meaning go back to Windows.  Once logged into windows, restart again.
- On Dell logo, now hit F2 to go to BIOS setup (NOT F12 as done earlier).  
- She noted wrong location, but for my new XPS13, the 'load defaults' was on bottom, slightly to the left, click it.
- Click BIOS defaults (NOT factory defaults), click ok.
- Say ya we good, hit ok again. 
- Then one more OK for good measure to exit/restart.

And viola.  Now my newly reset BIOS worked fine, as my network adaptor shows up, its finding networks, I re-added my network password and now online fine.

She indicated drivers were ok, rather it was BIOS settings causing the issue (and she knew answer immediately and was laughing as I told her, she acknowledged they most definitely knew about this, so I must not be first to call).

Anyway, hope it works out. To be clear I am posting this from my XPS 13 now after fixing it.

Thanks for the update, @pettyr!

I just loaded the BIOS defaults (there was no option for factory defaults for me). After the reboot the WiFi started working again, but previously it was pretty random when it worked and when not.

I'll watch it for a few days and if it keeps working, I'll be very happy.

evolevol,

I see in the case notes that you were offered an exchange through emails.

I didn't use the laptop for a few days and today I noticed that the WiFi was down again with same symptoms.

This means restoring to BIOS defaults didn't work.

Yes, ultimately the support offered me to replace the laptop or return the money.

I opted for the money, because I think having many different issues for over a month, even on a replaced motherboard, was a bit too much for me.

Until I get information on how the return will work, I still have the laptop and can test some suggestions.

I've had the wifi disappear a couple of times in last few days.  Killer on 9310.

Dell support told me today to update to the latest BIOS.  I had 1.1.4.  Now 1.2.5.

I'm good about updating drivers and BIOS frequently myself.  But this one did not show up in updates.   I had to search for it individually.

Not sure if it solves the issue yet.

I had the same problem with my new XPS 13 9310, network randomly not available Code 10 error with the Killer adapter. Emberassing for a new and expensive device, isn't it, Dell?

Thanks @pettyr for your solution. I did reset to Bios default, it worked, network is back.

Before that, I had the Bios updated to 1.2.5, which did not help.

Maybe now the problem is fixed, maybe it is not. Really not a good thing to have a non-reliable device, Dell.

Exactly the same issue

each time, I need to restart, press F2, apply changes, then restart again, then Wifi works again...for one day !!

just amazing

Dell please find a quick solution and come back to me asap, otherwise...

I'm having this problem too. Wifi adapter stops working with the following error in the device manager:

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

Restarts do not work. Reinstalling drivers does not work. A complete shutdown, waiting a few seconds, then restarting gets the wifi working again. Initially, even a shutdown didn't work but I did the reset to BIOS defaults someone mentioned above which got it working again. 

It seems to stop working if the laptop hibernates or goes to sleep sometimes.

I have the Killer driver version 1.0.0.1428 and the latest BIOS 1.2.5 installed.

Incidentally but unrelated to this issue, I also had this random blacking of the screen mentioned here that installing the Intel-direct drivers fixed: Solved: Random Black Screen issue on XPS 13 9310 - Dell Community

Today I had a dell tech come replace my system board, as my laptop was presenting many Blue screens to freeze ups and Red blue green white screen on boot up, Wifi was an issue too and I would keep uninstalling via device manager and it will work later which was annoying, but speak of the weasel my wifi card stopped working again with this new system board and I had to use windows 10 trouble shoot feature and shut down the computer and turn it back on, now it is working and showing networks, I had to reenter my password though. I hope its doesn't continue as I already got the system board replaced today! 

Same problem here on a 3 day old computer.  I’m waiting for a solution or I will return the computer.

I love Dell laptops. Exquisit devices. Great technical support.

And here is my painful experience:

New XPS 13 9310, networks not found, Dell Support found no remedy and advised me to return the device, which I did.

I bought another, new XPS 13 9310, which showed the same problem (No Network, Code 10)
Dell Support send a technician who changed the mainboard (great service!).

One week later, the same problem. That makes three brandnew Dell devices, each of them with the same defect.

Do I just have really bad luck beyound laws of probability, or is this a serious Killer Wifi issue, which Dell does not address, thus selling deficient laptops?

I have a XPS13 9310 and have had all the wifi problems listed above 

Dell has replaced the laptop and since then I have had 2 motherboard replacements but the problems still persist

I have done a lot of very deep digging to try and sort this and may have come up with an answer - I changed the channel number on my BT smart router from channel 1 to channel 11 (This was chosen automatically from the router software) I have had no wifi fails and when doing a wlan report (netsh wlan show wlanreport) most of my problems have vanished . Complete working without any errors could probably be achieved by installing a 802.111ax router which would work better with the AX500  board than my 802.11ac unit
