Have a user with a Dell Vostro 2520. Restored Win7 32-bit due to failed hard disk. No issues with anything except the wireless.
Dell's downloads has several wifi drivers, found the applicable one in "modems/communication" category.
It also installs the Bluetooth driver immediately after unzipping. The DW WLAN Card Utility it installs only manages "peerNetworks". I cannot figure out how to get the utility to manage wireless networks nor can I get Windows to manage wireless networks.
When I go to Network and sharing, and click Manage Wireless Networks it brings me to the wireless profiles window.
The installer is filename: DW1704DW1704_W7_A00_Setup-F9WG9_ZPE.exe
Conents of the unzipped folder are:
Custom
Win32
Win64
WLAN
Autorun.inf
BTW
...Bluetooth install files
I need to get the wifi working on this one.
