my wireless connection is quite unstable.

Hi, are you still having this problem? My iwlwifi is not crashing but my connection is very unstable to my 5ghz access point. Curious if we're running into related problems and if you've found a solution.

May be I have the same problem as you, I post a thread here: https://bbs.archlinux.org/viewtopic.php … 2#p1375472
