Hi,

I'm having major problems keeping my wireless connection up and running, 
together with bluetooth mouse on my Dell XPS13 (L322X, full-HD version).

I'm seeing regular firmware and hardware resets. I'm on kernel 3.12.7 and 
firmware loaded is 18.168.6.1. Hardware is Intel Corporation Centrino 
Advanced-N 6235 (rev 24). Wireless network is 802.11b/g, WPA2.

I've tried all possible combinations of module parameters without succes.

Last thing that comes to my mind is my legacy BIOS. Could anyone on this list 
either confirm or deny that instead booting the laptop in UEFI might help 
resolve the problems? Is anyone using this laptop with wifi and bluetooth 
mouse either using legacy or UEFI BIOS?

I'm asking because switching from legacy to UEFI seems to be a bit daunting, 
not in the least because the live CD's I tried have many problems recognising 
either the display adapter on recent kernels (ubuntu 13.10 boot CD black 
screen) or backlight seems to be broken (again) on 3.13.rc, using ubuntu 14.04 
boot CD).


Best regards,
