[Reece (reece)]

Same problem here on Ubuntu w/Dell 9310 and AX500 and 5.13.0-20 and -21.

Reverting to 5.13.0-19 resolved the issue. First reboot didn't fix the issue, but a full power cycle did.

I used a USB wifi dongle to install. Without that, you might need to grab the relevant dpkgs and put on a USB stick to update.

sudo apt install linux-headers-5.13.0-19 linux-headers-5.13.0-19-generic linux-image-5.13.0-19-generic linux-modules-5.13.0-19-generic linux-modules-extra-5.13.0-19-generic

[herrsaalfeld (herrsaalfeld)]

The 5.13.0-20 kernel works on this XPS 13 9310, but you may have to disable/ enable the device in BIOS (Connectivity -> WLAN and UEFI WiFi stack) before it appears again. Also possible that full power cycle does the job but haven't tried that yet. The exact sequence of steps required to reproduce this remains unknown to me but it looks like the failed attempt to load the device driver in the -21 kernel sends the system into a state that requires some BIOS activity.

I also have the same issue with Dell XPS 13 9310 when using the 5.13.0-21 kernel. I can confirm that 5.13.0-20 kernel works on this XPS 13 9310 with a full power cycle.

[Jeffrey Bolle (jeffreybolle)]

I have the same issue with a Dell XPS 17 9700 when using 5.13.0-21.

5.13.0-20 works with a full power cycle.

[Torsten Gilles (torsten-gilles)]

I have the same issue with XPS 9310 when upgrading from 5.13.0-19 or 5.13.0-20 to 5.13.0-21.
5.13.0-19 or 5.13.0-20 work both fine for me.

[prontospray (prontospray)]

I have the same issue, WiFi disabled when using the 5.13.0-21 kernel, regressing to the 5.13.0-20 kernel fixes the issue.

[Elia (zikoel)]

Hi, I have the same issue, Wifi disabled when updating to 5.13.0-21 kernel, I regress to my last version 5.11.0-34 (I will try with 5.13.0-20). To solve the issue I need to detach the battery from the motherboard.

[Rico Neubauer (ubuntu-etzenrot)]

@Elia, I have the same hardware and a full power-cycle (complete shutdown, then start) was enough for WIFI to show-up again in BIOS and OS.
Would try that first before touching the battery ;)

Revert to 5.13.0-20 was enogh for me as well.

[Elia (zikoel)]

@Rico thanks for the suggestion, I will try for sure! I tried to shutdown and restart after the kernel rollback but without lucky (for this reason I decided to remove the battery). Maybe I miss how to complete shutdown the laptop ?

[Rico Neubauer (ubuntu-etzenrot)]

"sudo poweroff" did it for me / alternatively press hardware-power-button for 5-10 sec until lights go out.
Disabling and again Enabling Wifi in BIOS might also help.

[Torsten Gilles (torsten-gilles)]

Wifi now works for me with my XPS 9310 when upgrading to new kernel 5.13.0-22.

[serinit (serinit)]

I can also confirm that 5.13.0-22 fixes the Wifi problem.

[herrsaalfeld (herrsaalfeld)]

Same here, works with kernel 5.13.0-22.

[Chad G (magicfish1)]

I still have no Wi-Fi nor Bluetooth with 5.13.0-22 on an XPS.

5.13.0-20 works OK.

Enable/disabling via BIOS, poweroff, power cycling, etc do not fix 5.13.0-22.
