i have recently reformat my dell inspiron n5010 laptop to windows 7 ultimate. my problem is that i can no longer detect and see available wireless connection. when i look at my device manager under Other Devices, i can see the "Network Controller" has a yellow mark with exclaimation point on it. but when i try to update it says, "Windows was unable to install your Network Controller".
Please advise me on how to do this properly. I have installed many drivers on dell.com drivers. my laptop is okay on wifi before i reformat it. I just reformat it due to virus concerns.
