Title:
WiFi sometimes connects, sometimes doesn't, sometimes stops, Kernel
bug
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I am using an old Sony TR1MP 32bit laptop, ubuntu 12.04 (the system is
not supported by later ubuntu versions).
I use a Micronet wireless USB dongle since the inbuilt wifi is very
slow, and is disabled by blacklisting it. The dongle shows if it is
working since it flashes blue when it does.
Lately the wifi connection often fails at boot, with the system not
attempting to connect (the dongles does not light up). Sometimes it
works, and then drops out later. Sometimes it reconnects by itself,
sometimes not. Sometimes removing the dongle, waiting and then
reinserting it works, sometimes not.
Looking at syslog, I see the attached Kernel errors when the
connection fails. The problem seems to have got worse recently. The
wifi has always been a little unstable, but is now nearly unusable.
I will gladly supply more information if someone can tell me precisely what is needed. I'm not an expert at linux, but not totally useless at it either.
