Title:
Kernel drops connection with rtl8192cu fixed driver
Status in linux package in Ubuntu:
Expired
Bug description:
I have experienced a strange error a month ago when Ubuntu 14.10
upgraded the linux kernel. rtl8192cu fixed driver stopped working. The
error is mentioned here:
http://askubuntu.com/questions/546195/ubuntu-14-10-rtl8192cu-
bug/609057#609057
The kernel 3.16.0-33-generic (maybe also some older) had this error
and an update from 3.16.0-33-generic to 3.16.0-34-generic fixed the
issue.
Identical issue popped up again with a kernel update in Ubuntu 15.04
from 3.19.0-15 to 3.19.0-16. Obviously the patches applied in
3.16.0-34-generic shall be applied to 3.19.0-16-generic again.
The following lines appear in the syslog all the time and the wireless
connection is not working:
