First, Thanks for the reply and info.
I'm using these in 4 desktop machines that don't have wifi
at all.
Found a number of drivers that failed to compile at all,
but found RTL88x2BU-Linux-Driver-master.zip at
https://github.com/RinCat/RTL88x2BU-Linux-Driver/branches
and it compiles with no real issues (some warnings pop
up, but no errors).
Do the make and then make install then devices are seen.
Did find have to make the device available for all users,
or it wouldn't activate automatically or have other than
root be able to connect it. Seems to work fine so far.
Haven't had a kernel upgrade since installing, but would
be under the impression that a kernel upgrade would
require a rebuild and reinstall in the new kernel
directory??
Just got a new router that had 5G, but has a different
public IP than my 2.4G one.
Thanks again.
