[sudo-discuss] omni wifi going up and down constantly

Fri Feb 9 16:07:23 PST 2018

Just another data point. Using wifi in the basement on the triple core
Debian box I was getting disconnected from the internet every 5-10
minutes, though the network manager claimed I was still connected. I had
to disconnect and reconnect to ping the world. I thought it was just me
and Linux's partial support for proprietary wireless chipsets, and spent
a couple of hours trying various newer kernels, firmware, compiling
drivers, etc., to no avail.

Last night I was on line for 7 hours or so and I don't think I was
disconnected at all, though a large file I was downloading seemed to
drop at one point (Kali Linux 2018.1 iso file, 2.9 GB).  So the problem
seems to be mostly resolved for me, thanks Yar and others.
