Let me try and explain this properly. I'm trying to set up a few computers in an office that currently do not have internet through their LAN connections. They are office sharing with, and the folks they are sharing with have a WIFI guest account, so they are piggy backing off of that using WIFI adapter dongles. Everything was working fine yesterday, and now Windows is throwing a fit about having multiple networks connected, even if only one is connected to the net. I've searched and searched the net and haven't quite found the answer I'm looking for.

You could try configuring the cabled network's DHCP server so that it doesn't give the clients a default gateway. That way, they should use the default gateway from the WiFi while routing LAN traffic on IP addresses belonging to the cabled network via the cable.

Also, what IP address ranges are in use on the two networks? They will need to be in different subnets (for example, 192.168.0.x/24 for the cable and 192.168.1.x/24 for the wireless) otherwise the clients won't be able to resolve routes.
