It wasn't missing driver, the new driver rtw88 is now responsible of driven RTL8822BE, not the staging driver rtl8822be that existed for some time (v4.14 ~ v5.1)[1]. In the old age, rtl8822be has a parameter "aspm" and users may disable it to work-around this issue, and that is not possible so far with the new rtw88 driver.
Can you have a try on https://launchpad.net/~vicamo/+archive/ubuntu/ppa-1879575? Let's proof that's the root cause first. You should run following commands to install kernel packages: $ sudo add-apt-repository ppa:vicamo/ppa-1879575 $ sudo apt install \ linux-modules-extra-5.4.0-33-generic=5.4.0-33.37+lp1879575 \ linux-modules-5.4.0-33-generic=5.4.0-33.37+lp1879575 \ linux-image-unsigned-5.4.0-33-generic=5.4.0-33.37+lp1879575 Note this ppa build may take several hours from now to finish. Reboot into the new kernel and attach system journal either it works or not: $ journalctl -b > journal.log Please attach that journal.log file as attachment here. By the way, I have also one RTL8822BE chip, but it works just fine in Focal.
