I've been all over the forum and have not found a solution which fixed my problem so I'm looking for some assistance - I'm sure my problem is fixable. What am I missing or doing wrong? PROBLEM STATEMENT; my HR21-700 DVR cannot connect to the internet. A "verbal" diagram of my network; COX isp SCIENTIFIC ATLANTIC cable modem connected by CAT5 to NETGEAR WGT 624 wireless router connected by CAT5 to SLINGBOX SlingLink powerline ethernet adapter (1-port) connected by home power wiring to SLINGBOX SlingLink powerline ethernet adapter (4-port) connected by CAT5 to HR21-700 AND Slingbox Solo. Most of you will know this but the Slingbox Solo is a device that streams live audio/video from the DVR to the internet. What is critical to understand is that when I disconnect the HR21 from the ethernet adapter, the Slingbox works perfectly - I can watch the DVR stream from any computer on my network, and by using my laptop on any outside network where it has an internet connection. So I think that validates that my network is set-up correctly, at least as far as what the Slingbox requires. When I connect the DVR to the ethernet adapter it can't get connected (even after rebooting all network components) and the Slingbox loses it's connection. The router is configured as a DHCP server; Gateway 192.168.0.1 SUBNET 255.255.255.0 DNS 192.168.0.1 IP address range is 192.168.0.2 ~ 192.168.0.237 The 3 computers on my network have no problems and display the above configuration values in their LAN properties. I originally had fixed IP addresses (per MAC address) for each computer and everything worked fine. When the DVR stopped working I removed all the fixed IP definitions and did the following more than once; Restore network defaults on the HR21 power off HR21, modem, router, both powerline adapters re-start modem, then router, then 1port adapter, then 4port adapter, then HR21. after the HR21 finishes booting, in Advanced setup, the IP address doesn't match the range specified by my router, the gateway and DNS fields are blank and the subnet address is incomplete (255.255.0.0). Thanks in advance for your suggestions.
