1) The release of Ubuntu you are using:
Description: Linux Mint 17.1 Rebecca
Release: 17.1

Ubuntu version:
Ubuntu 14.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
Maybe linux-image, linux-firmware or network-manager.

3) What you expected to happen
Permanent wifi connection.

4) What happened instead
Wireless is disconnecting randomly.

This wifi card was working for me with Ubuntu 12.04 for several years before flawlessly.
Now I installed Linux Mint based on Ubuntu 14.04 and it is now randomly disconnecting.
When it disconnects I disable wireless in the NM applet and enable it again and wifi reconnects.
Logs regarding the disconnect and the reconnect are attached to the report.

The disconnect happens 10 to 60 minutes after it was connected or reconnected.

The laptop I'm using is a Dell Inspiron N5110 which is officially supported by Ubuntu:

It seems that I'm not the only one with this issue:
