Sorry for x-posting but I wanted to get maximum coverage for this post as it's really annoying me.
I have a Dell laptop (Latitude D800) with built-in b/g wireless (Dell TrueMobile 1300) and a Linksys WAP11 Access Point.
On my AP I have WEP swtched on, MAC filtering enabled, and I have disabled SSID broadcast. I also use static IPs and have DHCP disabled for maximum security.
They have always worked great together.
Last weekend I formatted my laptop to clean it up and I wanted to install SP2 (it's Windows XP Pro by the way). Also installed the latest drivers for my hardware from Dell.
After the format I am unable to connect to the wireless LAN unless I enable SSID broadcast (which I obviously don't want to do).
If I turn on SSID broadcast, my connection works instantly. I can then disable SSID broadcast and it continues to work.
However, as soon as I reboot the laptop, my connection is lost and I can't get it back without re-enabling SSID broadcast.
I have tried it with Dell's software managing the wireless connection and with SP2 managing the connection. I have even uninstalled all the dell sofwtware except the driver needed for the hardware and still I get the same problem.
I don't think it's the Access Point, as I have another laptop with a Linksys PCMCIA card in and that works fine with the SSID broadcast disabled.
Has anyone got any advice please?
