Description Stephen Berman 2020-04-30 15:16:07 UTC
On booting Tumbleweed after updating to snapshot 20200425 the Network Manager shows no connection. When I open the Connection Systems Settings Module and click on my configured wifi access point, a PolicyKit dialog pops up requesting authorization with the root password. I enter the password and nothing happens, and the wifi remains unconnected. This is with kernel 5.6.6-1-default. When I reboot and choose kernel 5.6.4 from the Grub menu, on logging on the wifi connection is there and active, as usual. So this seems to be a regression in 5.6.6. This is with a Realtek RTL8821CE 802.11ac PCIe Wireless Network Adapter.

Could you give hwinfo output? Also give dmesg output after the boot on both working and non-working kernels, too. Thanks.
Comment 2 Takashi Iwai 2020-04-30 15:43:56 UTC
Also try the kernel in OBS Kernel:stable repo, if you don't use Secure Boot. http://download.opensuse.org/repositories/Kernel:/stable/standard/

Comment 7 Takashi Iwai 2020-04-30 16:17:45 UTC
Which kernel module are you using? It looks like the downstream driver, judging from hwinfo output.
Comment 8 Takashi Iwai 2020-04-30 16:19:32 UTC
One more favor: could you take hwinfo output from the working, 5.6.4 kernel, too?

(In reply to Takashi Iwai from comment #7) > Which kernel module are you using? It looks like the downstream driver, > judging from hwinfo output. I've attached the sorted output of lsmod. I believe the module for the wifi is from the rtl8821ce-kmp-default package from obs://build.opensuse.org/home:Sauerland

OK, then you'd need the KMP built to the corresponding target (Kernel_stable), I suppose.

Hm, so far every time I've done zypper dup and there was a new kernel, that module has also been updated. Maybe this time it wasn't or it was buggy.... Ah, just checked and there's a new module available, now running zypper dup... it's removing the 5.6.6_1-2.17 version of the module and installing 1-2.18... Update finished... rebooting with 5.6.6... and the wifi connection is back! So I guess the previous module was buggy but it's now fixed. So you can close this bug. Thanks for the feedback.
Comment 14 Takashi Iwai 2020-04-30 20:17:49 UTC
Good to hear that you managed to work. Let's close now.
