Hi All, I have a 5 month old Dell Inspiron 1564 with a Dell WLAN 1397 Wireless card. I was having some trouble connecting to my wireless router, and as a last attempt to get it working, I uninstalled and reinstalled the driver for my wireless card, using a fresh download of the latest version from Dell's support site. The driver seems to install fine, and when I look at the wireless card in Device Manager, it's enabled, but in "Control Panel\Network and Internet\Network Connections" (which can be accessed through the Network and Sharing Center), it is greyed out and says Disabled. When I click enable in there, a small window pops us saying "Enabling", then after a few seconds, it says "Enabled" then dissapears. However, the adapter stays disabled in N/W & Sharing center, and isn't picked up by Windows. I've tried reinstalling the driver through Dell's driver installer, as well as through Windows' automated driver search, and neither works. I also tried to do a System Restore, but that is not working (can't complete on any of the restore points). I also spent 1.5 hours on the phone with Dell support and their final advice was format and reinstall Windows. The same issue is reported here and here, with no apparent resolution. Can anyone offer any advice that I haven't already tried? Thanks! More details: - I am running Win 7 Pro. - Wired networking and internet connection works fine - I have Zone Alarm and Avast Anti virus, and I've tried disabling both to no avail The same problem has been posted by others here, here, here, and here. It seems to happen with various NW card brands.
