My main router IP address is 192.168.100.1. And secondary router address is 192.168.1.1. what should be the IP address of the secondary router so that it can be configured as a wifi extender. I have changed it to 192.168.1.2 but it didn't work. Any suggestions. Main router is Huwaei HG 8245H and the secondary router (Extender ) is Digicom DG-ZA204M.
