Yes, recompile and reinstall, but every few kernel versions you will likely
need to find updated code. It makes any out of tree driver a no go unless
the code is being updated. Each time it broke finding new code required
checking to see it was fixed and if not hopefully finding one that is fixed. It
was a major hassle. An in kernel supported pci card would be much easier
and or a real network connection support wise.
Just had a kernel upgrade for Linux machines, so updated
the 4 machines with the USB devices.
1. No wifi after boot since kernel didn't have the driver.
2. changed to directory with build (checked and show it
was updated 12 days ago, so seems to be active update)
3. Ran
make -j 8; make install; modprobe 88x2bu
4. All build and install fine, and wifi went active again.
Some of the other links I found had failed to build with
terminal errors. On actually had a link to ipx.h file, which
a search found it in older kernel src directory, but was no
longer in the current one.
So, seems to require what I expected.
Recall long ago, had a Linux server at College running
Redhat 9 I believe. It had 9 ethernet ports. One connected
to the Colleges 100M backbone that was running 3 Class
C networks. The other 8 ports connected to 8 different
classrooms giving each a 100M link to server. Had squid
running and was getting 40% cache hit ratio. Rest of
campus had like 900 machines all running directly off
backbone?? Interesting in labs running windows,
machines on the different class Cs could see each other
with windows shares? Wasn't my job, and MIS would or
didn't care. Every other machine had public IPs. Had 2
Novell Servers with Public IPs, and Linux Box, and a
Unixware box. But everything else was private behind
firewalls. Long ago. Retired now..
So, upgrade only took few minutes to build and install.
Thanks.

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.
