19.10 I have the 8812 realtek driver installed as well as dkms up to date

Sorry. I was trying to make it stand out for anyone else experiencing the same issue.

You can mark this thread solved by clicking on the thread tools drop down in the upper right. That would be the best way to show it off.

[johnbra]

Done. Thank you.

Well. The driver seems to work but connecting to my wifi is terrible. Not sure why but one out of 20 is bad.

I just bought one of these little jewels. It clearly states on the back of the box "Compatible with ubuntu Linux".

I followed the instructions at https://packages.ubuntu.com/eoan/all...-dkms/download . Then I did apt update and FONT=Courier New]apt upgrade[/FONT]. That was actually the wrong thing to do at this moment, but it needed doing anyway for other things.

root@jeffs-desktop:~# dpkg -i /home/jeffs/downloads/rtl8812au-dkms_4.3.8.12175.20140902+dfsg-0ubuntu12_all.deb

So then I want to install it:
[FONT]
root@jeffs-desktop:~# lsmod | fgrep 8812
8812au 1290240 0
cfg80211 712704 3 zd1211rw,8812au,mac80211
root@jeffs-desktop:~#
[/FONT]
I think it's there.

My next step is I am going to reboot and see what happens.

After rebooting, the module refuses to load:
[FONT]
root@jeffs-desktop:~# !1961
insmod /lib/modules/5.3.0-23-generic/updates/dkms/8812au.ko
insmod: ERROR: could not insert module /lib/modules/5.3.0-23-generic/updates/dkms/8812au.ko: Unknown symbol in module
root@jeffs-desktop:~# uname -r
5.3.0-23-generic
root@jeffs-desktop:~#
[/FONT]
At this point, I don't know enough about kernel internals to know how to proceed.

I am fond of telling my students to RTFM. There is a CD included in the box, and there is an install.sh file which invokes gcc (among other things). 2 of the programs do not compile. I am going to send a message to the manufacturer and see what they have to say.

I have an older adapter, so I am not down, but I am running slower than I would like.
