I don't know, Mike, I don't think they believe you. That was my first thought, too. I bet philhu could buy a HomePlug Ethernet adapter and leech off his neighbor for broadband...
wierd - 622 has ip address/dhcp and NOT PLUGGED IN!

WELCOME TO THE NEW SERVER!
If you are seeing this you are on our new server WELCOME HOME!
While the new server is online Scott is still working on the backend including the cachine. But the site is usable while the work is being completes!
Thank you for your patience and again WELCOME HOME!

In PC's some TCP/IP cards will show a generic IP when not connected. I've seen it on laptops I've gotten from work before.. I always found that to be odd..
They might have done the same so that via the power cord option they can have each box talk to each other..

Thanks VinceT3! This is exactly what I was going to post.
In my experience, many networking chipsets will use their own "ghost" IP address when there is no address being supplied.
As to why, ...that would be a great question and one I never bothered to look into researching as it would not change the outcome of what is happening, nor would it lower the price of fuel, healthcare or provide me with increased salary, but I digress.
Want to prove this? Unplug your newest computer from a network, bring up a command console (Start Button>Run> and type "CMD") and type "IPConfig /Release", which will release any IP address that it was using. Then type "IPConfig /Renew" and see that it will fail to obtain an address. After that, type "IPConfig /All" and it should show what I refer to as a ghost IP address.
Cheers,
Spence

No, it's not the chipset. Windows will assign an IP in the 169.254.x.x range whenever there's not one assigned and DHCP is not available. That range is reserved for automatic private IP addresses. The OS will use an ARP request to find a unique address in that range.
Since the 622 is Linux, and the OP said it also populated correct DNS information, I'm betting he has a HomePlug-compatible router or modem.
Thanks wonko!
I stand corrected, however could a network boot ROM do something similar?

TCP/IP stack never been a part of NIC chipset; PXE [boot ROM] is a program, short but with partial implementation of TCP/IP stack and some upper functions. OSes [Windows or *nix or MacOS or etc] have full stack support and more.
And after the boot ROM transfers control, the NIC becomes full reign for the OS's network stack to take over with its own [possibly different, but not usually] IP settings.
You are correct that there are two different approaches in play here.
The 622 has the homeplug chip built in, so it just uses its power cord to connect to the power line network. The adapter picture that you posted, would be what you would use to connect your router to the power line network. So the adapter would plug in to the power outlet and an ethernet cable would connect the adapter to the router. That adapter would bridge between the ethernet and power line networks. That in turn would allow the 622 to communicate through its power cord, to the adapter, and then to the router.
Yes, I do have a homeplug adapter in my house...
Never thought of that.....Interesting!
Sorry, but that's not correct;
there is no place in NIC chip to store IP/SM/GW data during PXE run before OS take control. Probably you mean DHCP server will keep the lease and then OS's request will fetch it while TCP/IP stack initializing .
The following document has good info:

Uh oh.
I have a 622 and a new purchased 722 on the way. 2 different accounts. One here and one "moved". No piracy going on here- only one receiver on each account. The plan was going to be to connect one to the home telephone line and one to the home DSL LAN. Are they going to talk to each other over homeplug and send back the same IP address to Dish even if I don't want them to?!
Should I get a VOIP adapter and VOIP account and have the new 722 use the VOIP phone to report its location instead of the LAN? (I wouldn't plug in the LAN cable to either receiver in that case.) Or how about a power line isolation transformer to keep the homeplug from working? Would a UPS work?
Some sort of power line filter that strips off the harmonics from the 120Hz sine wave should work.
I'm having a bad day. 60Hz, 120V.
Smith, I'm sure you're getting ready to say "110v", right?
