Part of the problem, as far as I've been able to nail it,
are my two Sennheiser wifi headsets which compete
for frequency. My RTL8188EUS usb-fingernail transceivers
(of which it so happens I also have two) always show up
with lsusb but have not worked with Leap-15.3 for some
time now, not even with new installs! How can this be?????
They kinda 'went' gradually, could it be that they are
'losing it' although for some reason they still work
better with Tumbleweed (and I have never heard of
such a process anyway)?
Nor do I know to what extent they can work on varying
frequencies as those are set out by the wifi router,
but which AGAIN should be identical on Leap & TW.
And then there is THIS:
https://en-us.sennheiser.com/what-do-i-do-when-there-is-wireless-signal-or-wifi-interference After doing the frequency hogging ritual referenced above, and plugging both the 81188 and the 88x2bu in under Tumbleweed (and 'connecting' to the 5g mode afforded by the 88x2bu) I got faultless operation on both usb wifi and the headset.
https://github.com/RinCat/RTL88x2BU-Linux-Driver/issues/94
which ALSO mentions the 81188gu's under Suse AND the
date is about right for when they started acting up on my Leap-15.3
"This driver should works through every official kernels, but
most users will use distribution modified kernels which I
cannot do much about that."
& THIS is no longer available:
https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Leap_15.3/x86_64/rtl8188eu-kmp-default-git20210519_k5.3.18_57-lp153.7.1.x86_64.rpm
So the problem is mostly on Leap-15.3 in that my 8188EUS's
just DON'T WORK ANYMORE while the 88x2BU drivers DON'T
EXIST.
Anyone know a chipset WITHOUT ANY such problems?
