I did an install of latest LTS on one small vivobook by plugging the AC600 wireless dongle in before the start and then going through the install. I was prompted for wireless password early in the process and everything worked. Wireless worked on the installed system, and dmesg shows rtw_8821ce "enabling device" line.

I then tried on a different vivobook, but was never prompted for the wireless password and the wireless device doesn't show up either from live image or after install.

I went back and tried the live image again on the first vivobook, but the dongle didn't work there either and starting the installation process didn't prompt for wireless passwords.

So between these two systems it worked exactly once for reasons I can't guess. The drivers are clearly in the LTS somewhere, but the installer mostly just never loads them. What I wonder is if the USB dongle usually isn't even powered up when the probes are run, but I don't know how to check for sure if that's what's going on.

I also tried the newer version (non-LTS 23.10).

On the live image for 23.10, the output of lspci -nnk | grep -iA3 net; lsusb; uname -r is:

This makes it look like the USB dongle is at least powered on?

Note that the MEDIATEK device is the internal wireless card that I've read doesn't work on linux.

Any ideas?

    Does this answer your question? My wireless/WiFi connection does not work. What information is needed to diagnose the issue? – waltinator Oct 22 '23 at 23:52

    Please edit to include results from terminal for lspci -nnk|grep -iA3 net; lsusb; uname -r – Jeremy31 Oct 22 '23 at 23:57
  • It may help if you're specific as to what exact system you're install; you mention latest LTS but this means what exactly? Ubuntu 22.04 LTS I assume, which has had three kernel stacks provided on its ISO's (5.15 or the GA, 5.19 & 6.2 being HWE kernels) but you didn't provide provide more than latest LTS. Further, hardware varies on machines, even when the same make/model (particularly for popular models that are manufactured more than 3 months as newer/cheaper chips replace older chips) so its possible your machines have different chips in them. – guiverc Oct 23 '23 at 01:11

8821ce is most likely an internal Wi-Fi module of your second laptop. It worked once and then failed to initialize for some reason. For your AC600 dongle you need to install an additional driver. Check this page out for more links:

  • By golly you're right, I was led astray because last time I tried with that laptop the wireless didn't function at all land the internet seemed to be saying MEDIATEK just don't work. It works every time from the installed OS, I wonder what's changed that the installer doesn't seem to bring it up successfully now – Britton Kerin Oct 23 '23 at 09:30
