WiFi with F22 bad performance

[Frank Elsner]

Hi Community,

after installation of Fedora 22 on a Lenovo C200 I have the problem that WiFi 
performance goes down from time to time.

I've already added "options iwl3945 11n_disable=1" for the module.

The normal performance is around 14 MB/s and suddenly it goes down 
to under 1 MB/s. Disconnect/connect sometimes helps.

When running the good old fedora 14 I've never seen a problem
with WiFi on the same laptop.

Any pointer to a solution is very welcome.


Kind regards, Frank Elsner
