RTL8192CUS-based USB WiFi dongle
I have never had any connection issues. My other laptops have been able
to remain connected with open SSH sessions to remote systems for days at
a time without disconnecting. I should mention that I now make sure to
ping my router, not the Internet, to check if the WiFi interface is
working properly. Since my Internet is reliable, it doesn't make much of
a difference, but this way, I eliminate potential error sources.
The USB dongle listed last was purchased today and is plugged into the
Lenovo as a workaround for WiFi until it's fixed. It works perfectly
fine if I use the rtl8192cu-fixes driver. I unplug it whenever I test
the internal WiFi for this bug ticket.
(Is it just me, or are all the Realtek WiFi drivers in the kernel kind
of unreliable? This is not the first time Realtek chips have given me
trouble.)
