Fresh Manjaro downloaded yesterday installed on a desktop without builtin wifi adapter. Two wifi dongles at hand.
Dongle 1: inxi gives me “Realtek 802.11ac NIC” with chip-ID=0bda:c811, but the wifi setting page remains “No Wi-Fi Adapter Found”. But this dongle works on Ubuntu out of the box, without rtl8821cu or any such random drivers.
Dongle 2: it works for like 30s, during which I could connect to a network and open Firefox, but suddenly the system halts and responds to absolutely nothing. Caplock/numlock indicator on the keyboard doesn’t respond. The magic REISUB no longer works either. Again, the dongle works on Ubuntu without problem.
Any help on either dongle is appreciated.
Developers might be interested in the second one, cuz it seems to me an indicator of a serious bug deep down, in which case I’d like to help the debugging.
Manjaro: 22.0, kernel=6.1.1-1
Ubuntu for comparison: 21.10, kernel=5.13.0-52
(I recommend installing the`dkms1one, as that will be rebuilt on kernel updates, where the other ones wouldn’t.
So you can install it with:
pamac buid rtl8821cu-dkms-git
And reboot. If everything worked according to plan, your wireless should now work.
If, however, it doesn’t reply to this thread and provide the info according to:
also, then provide the output of:
Hope this helps!
All I can say is
When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:
This will just cause it to be rendered like this:
eget nisl elit id
arcu erat varius
cursus sem quis eros.
Instead of like this:
Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.
Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.
Thereby increasing legibility thus making it easier for those trying to provide assistance.
For more information, please see:
Also, if your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:
This will just cause the terminal output to be in English, making it easier to understand and debug.
