just gotta figure out how to put it in bridged mode lol because the interface on this router is weird.
Disable wifi under Wireless. Disable gateway and UPnP under Status > Capability. Make a note of router IP address under Status > CM Status. Change the password and make a note of it. Reboot.
I use an Asus RT-AC66U internet router. It can be used as a router and it's really easy to set up as an access point or repeater. (As are their other RT routers since they use the same firmware.) Asus firmware support is really good as well.
