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

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.
