I've been given a Dell Latitude D420 (WinXP Pro SP3) laptop, and it had Intel PROSet/Wireless software installed. It worked, but I had difficulty connecting to some networks (probaly I just wasn't used to it). So, I uninstalled that Intel software (via Control Panel > Add or Remove Programs > ...).
I then tried to turn on Wireless Zero Configuration, (Run > Services.msc, etc), and WZC now has Status "Started" and Startup Type "Automatic", but even after a reboot, no wireless icon appears in the Sys Tray, so now I can't get any wireless connection. (I can still get a wired connection though.) No joy with Googling yet.
Any ideas how I can get this WZC to work?
