I'm trying to use a spare router as a wireless access point on my network - I've given it a static address and disabled DHCP, however when I plug this into the network I end up with two ipv6 addresses!

Why do I end up with two IPv6 addresses? How can I monitor / prevent this?

Also even though there's a single IP address, there's only 1 (IPv6) DNS server address. It seems that windows is picking arbitrarily. Only one of the routers has DNS enabled so this is a problem.

One quick way should be to connect the second wifi-only router's wan port to a lan port on the main router. The wifi-only router will see the main router's network as "the internet", and have the wifi router just use it's default configuration.

Connecting to devices on the wifi router's network might be tricky, perhaps requiring port forwarding on both routers, but this setup should be fine for most general net & web access.
