Currently my setup, which works fine, is
I have
Sorry, I don't know much about this networking stuff ...
1. a modem/wireless router and
2. a wireless router connected to 1 as a wireless bridge and my laptop, etc. are plugged into its LAN ports.
I have
3. another wireless router that I am trying to connect to 2 via cable - LAN port to LAN port - to have wireless in the room with 2.
I haven't been able to figure out what the settings should be. I've disabled DHCP on 3 and set it's LAN IP number to be one greater than 2. I've included a screenshot of the WAN settings page for 3 below - the IP addresses that I thought should go in there are not accepted by the router software and it won't allow me to save them.Sorry, I don't know much about this networking stuff ...
