Bug Description
Similar to bug : https:/
Saw the following in the logs :
Aug 13 17:22:52 Galois kernel: [32696.796323] iwlwifi 0000:02:00.0: restoring config space at offset 0x1 (was 0x100006, writing 0x100406)

When I first wake the computer, or boot the computer, wireless attempts to connect about 15-20 times before finally connecting.
Once connected, speed and latency vary randomly, but mostly on the slow/high side respectively.
When I test my connection speed with a site like speedtest.net, I'll usually get full speed for about 1/2 a sec , then it goes to zero for awhile, then comes back on at full speed a second later or so.
With windows, connected to the same router, none of these problems occur.
