WN3000RP WiFi Extender issues (another!)

Thanks for your response. I think you might have misunderstood me about the Static IP address, or perhaps I am using the incorrect terminology. The computers accessing the Repeater or Router are not using static IP addresses, they are using DHCP. The WNDR3700 router is set to issue the same IP address to the WN3000RP repeater based on its MAC address. Anyway I did a factory reset of the repeater, and re-set it up and ended up with the same issue. After some more playing around I have now eventually gotten it working. What was not clear from the instructions is how to properly set up the ACL (Access Control Lists) for Wireless. As well as adding the MAC address of each device that you want to allow connection to on both the WNDR3700 and the WN3000RP. You also have to add the virtual MAC address as shown on the WN3000RP attached devices list to the WNDR3700 router. It's a bit of a pain to have to add 3 MAC addresses every time you get another wireless device, but it seems to work.
