Ubuntu 18.04 => 20.04 no connection after upgrade

Open 9Lukas5 opened this issue 4 years ago • 6 comments

Hey, I assume it's most likely not a driver problem, but I've no idea where to start looking for the fault:

It worked fine under 18.04, did the upgrade to 20.04. First compilation for the new kernel (5.4) failed with the state I had locally, so I removed the driver, pulled latest code and rerun the installation script without errors.

The wifi comes up and sees the networks just fine, but it doesn't connect. Neither 5Ghz nor 2,4Ghz networks. Checking dmesg output before and after a connection attempt looks exactly the same.

I noticed, that since the upgrade the service NetworkManager-wait-online fails to start. restarting this service doesn't change anything. The usb-lan card I've attached works just fine.

Any ideas, where to look / what to try?

Any NetworkManager logs while trying to connect to a Wi-Fi network?

Hey I have checked the logs for a working connection attempt on 18.04 and the failing one on 20.04

18.04 working connection:

Last logs presented show a problem with WiFi authentication. So either the supplicant has wrong credentials or they're not even present. Is there no authentication screen present to input a password at the time? Try removing the WiFi connection information and re-adding it.

tomaspinho avatar Jun 13 '20 12:06 tomaspinho

It is, but the password is definitely the right one. I can connect to a hotspot from my phone, but with my normal APs it's not working

9Lukas5 avatar Jun 13 '20 13:06 9Lukas5

I just checked it with a different hardware as the 20.04 install is on a usb stick.

On the other laptop the wifi immediateley connects without changing the password, on the rtl8821ce it fails 🤔

9Lukas5 avatar Jun 13 '20 14:06 9Lukas5

I have stable this module on Kubuntu 20.04. In 18.04 I had issues with compliling module (gcc version). But after compile module works well. In Kubuntu 20.04 it works fine with all kernels whuch I used. Only newest 5.8 can not be compiled now. Waiting for patch.

Additional info: I had Installed 20.04 from scratch, compile module by dkms, etc. May be on upgrade stage was some mistake and it still kept. Try to reinstall(not upgrade) Ubuntu 20.04.
