Well this is a kick in the gonads. My fourth attempt to find a good router has hit a roadblock barely a week since installation. I bought a Billion 6300wxl and it doesn't seem to support loopback. My laptop can be set to use the internal IP address but that's not going to help my mobile. I have to leave that set to access my servers using the domain name. The only solution there seems to be to leave wifi disabled.
I've also tried setting up a static IP address for my domain on the router pointing to my server but it seems to be ignored.
Does anyone have any other ideas?
