Ok still cant get my unsupported MRV to work since i changed routers. I have an apple airport extreme. My dvrs are hooked to the network wirelessly thru cisco WGA600N and the WAP610n. i originally thought the WAP610n was defective because it kept dropping the wireless signal. I switched the adapters to different dvrs to see if that would make a difference and it did. So I have been able to connect to the internet using either adapter on either dvr but even though the network says connected the dvr do not see wach other. I have tried different IP addresses and dns servers. The sub net on both is the same. What do i need to do to get the dvrs to see each other. I did reset the dvrs too. I am thinking of going powerline at this time.
