WiFi problems with M3800, any solution?
Hello, all. I have purchased a DELL M3800 running Ubuntu 14.04 preinstalled and while I love the form factor, I do not love that the wireless seems to drop off and I constantly have to run "sudo iwconfig wlan0 power off" to get the Intel chip out of power saving mode which seems to work most of the time.
From Googling the Intel AC7260 that comes with this laptop, it looks like others have serious problems with it too. :(
It doesn't matter which AP I'm using or what security. Networks where Android, iOS and Windows devices have zero problems are problematic for this laptop.
Is there any fix out there that anyone can point me to? Please let me know!

Are you sure you have an Intel chip? My wireless info is:
$ lspci
...
06:00.0 Network controller: Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter (rev 03)

Quite sure... for example:
$ lspci | grep Intel | grep 7260
06:00.0 Network controller: Intel Corporation Wireless 7260 (rev bb)

'sudo lshw -C network' will let us see a bunch of info, including what driver you are using.
