Public bug reported:
My wifi connection becomes practically unusable after some random time.
Reseting the connection helps for a while. Link speeds drop severely even
though the signal is strong. This problem doesn't occur with the same hardware
on windows. Tested with several different access points. No specific output in
logs. Previously I suffered from the following bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/736171 but now I don't get
any messages and the connection is much more stable than before so I guess this
might be a separate bug.
Screenshot attached with transfer speeds in my local network (after I reset the
connection every think becomes fine for a while).
