Just installed latest-greatest 22.04 Xubuntu, went rather smooth except ran into the same problem I had months ago with Xubuntu.
I do not recall dealing with this in the v20 of Ubuntu.
6.5.0-26-generic kernel does not have the right driver for my wifi module, which is rather common.
It's detected all right. The system sees it. Just lacking the driver, so that the settings menu doesn't even present the wifi menu.
I ended up tethering my mobile device, running apt-update, then rebooting and it was there, got it running.
One shouldn't have to do that however. I haven't had any issue with this in N other distros.. (I've had other issues but not with wifi).
