Actually, it turns out I can hardwire the nameservers into the DHCP
settings instead of using the router as the nameserver.

It also turns out that the router has some issues with nameserver
lookups that the developers are aware of, but haven't fixed yet.

Having hardwired the nameservers (so I'm no longer using the router as a
nameserver) everything is working peachy now.

Thanks John for all your assistance.
