Title:
[Inter 7260] Very slow and unstable WIFI
Status in linux package in Ubuntu:
Expired
Bug description:
Using an Asus Zenbook UX303L, with the last kernel, wifi is almost
unusable. The connection is VERY slow and keeps dropping.
There was absolutely no problem with the linux-image-3.13.0-40-generic
kernel.
Tried turning off the power management of wlan0 without any changes.
