I'm having DHCP issues with my ReplayTV5500, which I've had for years. I used to use 10.1.1.1 as my router address. I was working on some VPN stuff and changed the router address (and thus dhcp scope) to 10.1.2.1. This caused my ReplayTV to no longer connect, since it was holding onto 10.1.1.15. I did a release/renew on the ReplayTV, but it can't hit the gateway of 10.1.2.1. So, I changed the router and all back to 10.1.1.1, but still no luck. What I'm seeing on the router is the ReplayTV pops into the DHCP client list, but the address expires in 60 seconds. What's causes this? After 60 seconds, the ReplayTV is dropped. No physical changes have been made. No firmware upgrades. I just switched the IP, and then switched it back on the router. Is this a router issue or a ReplayTV issue? I can't believe that the ReplayTV is having hardware issues, since it worked fine until I changed the network and released its dhcp info.
