Q: I would like to use my own WiFi router instead of the repeater, and use the repeater to give Internet to my router. Can I do this?
A: Yes, you can definitely do that! It’s as simple as plugging the WAN (Internet) port of your router into one of the LAN ports of the repeater. You would connect all of your devices to the WiFi signal associated with your router (not the one associated with the repeater). Aside from that, configuration of the repeater will work exactly the same as if you were directly connected.
