I have 2 Draytek P700 repeaters positioned in the house with thick walls. I can connect to the first one OK but am unable to connect to the 2nd. Both repeaters have been configured identically apart from the IP address. Does anybody know if there is a fundamental setting that I have missed?

Are they configured as access points or universal repaeters or WDS?

They should be on different channels? (assuming left configured as access points)
