Windows 7: Dell Inspiron 1545 Wireless Issue

Hello! basically I've got a Dell Inspiron 1545 laptop which is supposed to have vista home basic on it but have re-installed it to seven home basic instead, and in the past few weeks I've had issues with my wireless adapter in the laptop, if im playing an online game such as World of Warcraft my wireless card will automatically disable itself and wont come back on until i restart my laptop which is a major pain at times, I've tried re installing the laptop several times to see if that fixes the problem which it hasn't so if anyone could help with this issue i would be very grateful D:



Cheers!
