See my comments in post #5.
The 72.xxx.xxx.xxx address is probably the address assigned by your ISP to your connection. This will also show up as the WAN address in your router's status page. The 192.168.xxx.xxx addresses are assigned by your router (via DHCP or a static setup) to devices in your local network and Network Address translation is used to allow the devices to contact the internet.
If your receiver cannot receive an address via DHCP, it will self-assign a 169.xxx.xxx.xxx address. This will allow DECA to be used for MRV between DVRs and receivers even if you don't have a router or internet connection, but On Demand, Media Share, Directv2PC, etc., won't work that way.
Does the router show that is is connected to any devices other than your receiver?
I hope you can help.....DTV and ATT were useless after 1.5 hours and an endless loop of CSR's.
I checked my ethernet cable again and it connects to my laptop fine.
I tried the top and bottom ports on my DTV receiver and no acknowldegement from the 2WIRE via light. I also did factory resets.
I am still getting the IP 169.xxx.xxx.xx on DTV set up and showing NETWORK ok and no INTERNET connection (13).
ATT was no help determining if ports 80 and 8080 were open or not as asked by DTV. DTV basically said I was on my own to call GEEK squad that it was intended for plug and play.
I can get into user definded settings on my router firewall where I tell it ports, ranges, etc. basically to identify my DVR but dont know if that is necessary or what to put even.
Any more ideas?
