Niko Nieminen, did this problem not occur in a release prior to Trusty?

As well, could you please provide the missing information from
https://wiki.ubuntu.com/Kernel/LinuxWireless ?

Title:
  [Dell XPS 13 9333] Wifi drops on Intel Wireless 7260 when unplugged
  from charging cable.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I can't use wifi with my home router (Netwjork 150Mbps) while plugged off from charging cable.
  When I am not plugged into the charging cable wifi might work a while but soon the signal will drop into just one bar and network will become unusable. As soon as I plug back the charging cable the signal also comes back and network is usable again.

  I think I do not have this problem with ASUS RT-N53  which I have in
  the office.

  Syslog output when I plug in my charging cable:
