I've been using a Vigor 2766vac for a couple of years without issue.  However, last year I changed ISP which meant I lost my copper phone line & despite telling Sky (new ISP) that I would be using a Draytek for connectivity they didn't mention they don't support digital voice on 3rd party routers.

I've reconfigured my 2766vac as an access point on the same subnet as the Sky router (192.168.1.x address), disabled DHCP & connected them both via the LAN ports.  The problem is, the sky router is now allocating what appears to be internet IP addresses (DHCP range is configured for 192.168.1.x) to the devices on the network which are unroutable.  If I allocate static IP addresses, DNS resolution fails regardless of what I put as the DNS server.

Has anyone managed to reconfigure a 2766vac to an access point & connect it to a Sky router (FTTC) successfully pls?
