Hey all, every once and a while my iwlwifi crashes, I'm not sure if this
is the best place for this, but if not please just let me know.
The wifi will work again after a few minutes, but it can be pretty
annoying.. Sometimes its fine, other times wifi is useless..
Kernel is 3.10.25:
Here is the dmesg dump, and more information from iw below, hope that
helps...
This is a laptop with a Intel 6235 Wireless minipcie NIC
