It reconnects on its own after some time, sometimes as soon as a minute and sometimes as long as 20 minutes. At first I thought something is wrong with the wifi adapter so I switched on my laptop and noticed that the same was happening to the laptop as well.
sounds like wireless interference OR a faulty adapter
how many devices are connected wirelessly ?
lets see an xirrus screen shot with the adapter and PC in normal position
------------------------------------------------------------------------
Run Xirrus Wi-Fi Inspector
Download and install
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and install the program.
You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.

{If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}
Then run and install the program - on a wireless enabled PC/Laptop
if you get an error - You need will need to have
NET Framework installed for the WiFi Inspector to function.
On windows 8 - (i do not have windows 8) but, it would appear that, When you first try to run, you may get a message that .net framework is needed, and included in that message is a link to download/install.
Run the program
A user guide is available here

Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".
note: the signal level is a negative number, so for example -88 is worst and -40 is better
If you are using the Mac OS then use

if you want to optimise base station position and signal strength / dead spots use
http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal
