JRulz,   Did you install the drivers in the correct order? How to Download and Install Drivers in the Correct Order     Rick
I have a Inspiron 1520 which came with windows Vista and I recently did a Windows 7 clean installation. There were no drivers specified for Windows 7 in Dell Driver Download so I installed Vista drivers, connected to internet via LAN Cable and upgraded most of the drivers. WiFI networks could be detected when installed for the first time but after a shutdown it never detects again. Sometimes it randomly detects, I tried using the laptop for 2 weeks now and only 2 times the WiFI automatically came up. There is a switch to pull after turning on WiFI radio, which will display the list of WiFi networks in a window, that Switch is not responding now. I installed Windows 7 Ultimate x86. Please let me know your suggestions. Thank you. JRulz
