I have recently bought a new laptop and it has an Intel 7260AC wireless card in it. I am getting regular wireless dropouts occurring at no specific interval. AFAIK this only occurs at my house.
Things I have tried
- Update to the newest mainline kernel (3.15)
- Update to the new drivers on the intel website (copied the iwlwifi-7260-8.ucode into /lib/firmware and rebooted).
- Turned off power management
- Switched home wireless to WEP
I'm at a loss for things to do. This is absolutely crippling at home.
Here's some outputs of various logs
dmesg

Is it possible "iwlwifi-7260-7.ucode" is conflicting with "iwlwifi-7260-8.ucode"? Should I remove it? What else could be wrong? I just cant believe that its my router if my brand new laptop is the only device in the house affected by this.
wlan0: deauthenticated from 00:14:bf:eb:1e:8a (Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA)
is the important part ofdmesg
. Have you checked the rest of the logs?sudo egrep 'wlan0|cfg80211' /var/log/*
