I know that there was a problem with the WiFi driver for this computer. To read about it google "inspiron n5010 wifi" and click on the first result. (i can't post url) At the second page someone says that dell updated Package R252544 for Dell Wireless WLAN 1520 Half MiniCard and now it will work. Is it true? I reinstalled Windows 7 and still don't know which driver i should install and i can really use help. Thank You!
