Wifi connection issue with Dell Inspiron 1420 laptop

Hello,

I have an issue with wifi connection on my Dell Inspiron 1420. The connection gets disconnected every 2min, again I have to disconnect and connect to the wifi. There is no issue with my wifi as I am using few different devices connected through the same wifi connection.

I do not know what is wrong may be something with the drivers not sure as I am not familiar with that area.
