Some further info: I rolled back to 19.10 using the 5.3.0-51-generic and rtwpci and rtw88 work well. But as stated before, when going to 5.4.0-28-generic (and -26) I am suffering from what appears to be this bug.
My wireless adapter is an RTL8822BE which shows up in lspci and lshw -C network, although under 5.4.0-28 lshw shows it as disabled (it appears to work for a few seconds after startup). dsmeg shows some issues with changing the power mode of the device although I am too much of a noob to understand it. Interestingly, wireless seemed to work on the 20.04 live version (from USB). As I said, I rolled back from 20.04 so I no longer have access to a 20.04 machine, but can reinstall it if there is any useful debugging to be done. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838133 Title: realtek r8822be kernel module fails after update to linux kernel- headers 5.0.0-21 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838133/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
