How are you connecting the HR20s - with the ethernet ports or with SWM/DECA?

Thanks for the reply. I'm connecting them with the SWM/DECA adapters. What's odd is that when I connected each receiver, it let me do the entire setup without a problem. Since I have no phone lines attached to the receivers, wouldn't it have had to utilize the internet connection for certain parts of the setup, like the downloading of guide information or for verification of my receivers? If so, I'm not sure why they were able to access the internet when my computers couldn't. Are they somehow hijacking the router from everything else on the network?

So you're also using a DECA Broadband adapter?

They really don't need access to DTV for setup - they get authorization and other information from the satellite feed.

Yes, I have the DECA broadband adapter. I thought it might be the adapter conflicting with the router, but I have it connected now with both the ethernet and coax cables and it is not causing a problem. It's only when I try to add one of the HR20's to the network through the DECA adapter. Do I need to set some network settings in the setup menu of the receiver? Since neither of my HR20's is currently connected to the network, I'll try connecting the HR24 and see what happens. It might tell me if the problem lies with the HR20's and/or their DECA adapters since the HR24 doesn't use one.

I can't imagine what's going on, but are these HR20-100s possibly? You said they were HR20-700s, but the 100s have all kinds of weird issues and require different DECA parts.

No, they're definitely HR20-700's. However, the HR24 is actually a HR21-100. I hooked it up and, for the most part, it seems to be working fine. I say "for the most part" because it says my STB Services are working, but that the connection test failed. Not sure what that means.

As far as the HR20's, I'm still having the same problem. When I hook one up, it kills the internet for everything else; disconnect it and internet is back. I've tried entering the network settings manually and giving each receiver it's own reserved, static IP address, but still no success. When I try to connect the receiver to the internet, I get an error message that says the ethernet cable is not connected, even though it is and I have verified that it is working.

Not sure what to do next. It must be something specific to the receivers since it seems highly unlikely both DECA adapters would be bad. Any suggestions?

Thanks,
Tim

Do you have all green-label equipment (especially the SWM) or are you using Band Stop Filters?

As far as I know, all of it is green label. I can see the green labels on the SWM, the DECA broadband adapter, and the two DECA receiver adapters on the HR20's. I don't know if the splitter and the PI require green labels and, based on how they are currently mounted, I can't confirm they are, but I bought everything from Weaknees in a single order, so I'm guessing they're also green label (if green labels even apply to those two components.)

Also, now that I've discovered I have an HR21 instead of an HR24, do I need a DECA adapter for that as well? If so, why does the networking of that receiver seem to be working without it?

Do you have any units plugged into ethernet?

What can you do on the HR21 that shows it's networking?

When you say plugged into ethernet, do you mean connected to the network or actually plugged into the ethernet jack in the back of the receiver? The HR20's have one end of their ethernet cables connected to the ethernet jacks on the DECA adapters and the other ends of the cables currently disconnected because of the killing-my-internet problem they cause.

That's a good question. When I did network setup for the HR21 (connecting directly to it's ethernet port, no DECA adapter) it ended with a "congratulations, you successfully connected to the network" type message, gave me "OK" for my IP and DNS settings, and confirmed that I was connected to the network and the internet. I also manually set the ports for the STB & Audio functions and forwarded those ports on my router. It told me my STB/Audio functions were successfully started, but it also gave me that message that said the STB/Audio functions connection test failed. I'm not sure how it can be successful if the connection test failed, but that's what it said. Now, when I run a system test, the only error message I get is that I have no phone line connected, which I know and thought wasn't necessary.

As far as being able to do anything that shows it's networking, I'm not sure what I can do other than run the system test since, even though I've activated Whole Home, without the HR20's on the network, I can't really test it. There is one odd thing, though. When I manually set the IP and DNS settings on the HR21, it accepted the static IP I gave it, it is recognized by that IP on my router, but when I do the "Connect Now" thing and it successfully connects, the receiver changes the IP to something else (I believe it might be the IP assigned to me by my ISP.) The router still sees it as the static IP I gave it and network functions seem to be fine. If I want to change something in the network set up, I have to change the IP back to the static one I gave it, because if I leave the one it changes it to, when I go to "Connect Now" it flags the IP as being incompatible with the DNS setting, which is the IP of my router. Very strange. (Hopefully I explained that in a way that makes sense.)
