[Launchpad Bug Tracker <1444766@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

1) Ubuntu Version: 15.04 (Vivid Vervet)
2) Kernel Version: 3.19.0-12-generic

Wireless: Intel Wireless 7265 (on Thinkpad X250)

3) I expect Wifi to work as expected without connection drops.

4) I am experiencing sudden connection drops, which means I am not able
to connect to anything after a certain time and it seems that it only
happens after certain amount of data has be downloaded. Although the
Wifi still appears as connected, it behaves like it isn't.

Other:
When I am booting with Kernel 3.16.0-23-generic I do not experience any Wifi connection problems at all.

(I am not sure if this bugreport is fine, as this is the first time I am reporting a bug here, I will be happy to do improvements to the report if I did anything wrong or provide as much data as possible upon request.)
