Windows 2003 domain and wireless network?

Hello,

I want to setup a Windows 2003 domain on my wireless network at home. A have at Windows 2003 (R 2) server that I promoted at the Domain controller and I’ve also installed DNS on it. I have 2 wireless laptop and one computer that will also connect. I also have a Netgear wireless gateway CG814WG v2 that was provided by comcast with a WEP 128 bit.

When I try to join the domain with my wireless laptop it get the message that the domain controller could not be contacted. What am I missing? My domain controller can get out to internet, I can ping it, but can’t join the domain.

Please help

Thanks
