Unstable wifi connection in Ubuntu 14.04 64-bit on Asus R510J

Question

I have recently upgraded to 14.04 64-bit and since then my connection to my home WiFi network has become unstable, the computer often randomly disconnects and the ping commands often indicates loss of packages.

This is a major issue for me especially because I use many webapps as replacements for programming and productivity desktop apps.

My computer is an Asus R510J, I have another computer that runs Windows 8 which has no problem with my home WiFi network, the same goes for my tablet and my smartphone. Also, I brought my Ubuntu 14.04 Asus computer at work and there it had no problem with the WiFi connection.

Here is my WiFi info:

another interesting fact is that when i bring my personal laptop to work, i have no wi-fi unstability issue, it works perfectly — OmekaPhive, Jun 24 '15 at 17:46
Did you move anything around at home (if so, put it back)? Did you have customized wireless hardware settings to boost power/range (these would need to be redone)? — Daniel, Jun 28 '15 at 23:48
@Daniel for both questions i did not do anything of that sort — OmekaPhive, Jun 29 '15 at 17:25
Try upgrading to 15.04. There may have been a bug fix for that. — Daniel, Jun 29 '15 at 19:22
Disregard the comment to upgrade to 15.04 as 15.04 is a STS and 14.04 is an LTS and provide more information on your Wireless set-up. Please [edit] your question to provide the contents of wireless-info.txt — Fabby, Jun 30 '15 at 07:53
