Internet connection slows to a crawl when I turn the DTV receiver and TV on.

We recently had 2 Hr24's installed with the whole house connection. The installer connected the whole house black box (with the three blinking lights) to our router upstairs and then connected it between the two tv's with coax cable. The connection has worked fine for three weeks, but all of the sudden we get a message on the TV that the internet connection is lost and the computer internet upstairs slows to a crawl.

We were going to call DTV, but are wondering if there might be an obvious fix.

Our installer said to definitely never connect ethernet cables to the system. We were not certain why he admonished us so severely. So far we have heeded his warning and have not connnected any ethernet cables, but are still having problems.

BSparks,
He admonished you to not connect the HR24s directly to your internet connections because that kills the Whole Home DRV functionality. Something has whacked your local network between your SWM dish and your receivers and the "black box". Quickest thing to try is to unplug both your receivers and your "black box". Then plug in the "black box" and wait about 2 minutes. Then plug in one of the receivers and let it come up completely (about 4 minutes). Once that is complete plug in the other HR24 and let it come up. You may read elsewhere on this forum that this is an urban legend, but this is exactly how my installer's D* tech support had him bring up my system when we could not see the recordings on my DVRs. The reason this impacts your home internet is that it cripples the router when you have IP conflicts down the line. (Bear in mind that the whole SWM setup is a private network and all the pieces of that network have to be working right to interface correctly with your outside network.) Please post if this works for you.
Bob

Check the network activity lights on the DECA (black box) and your router. See if either are blinking rapidly when this happens. It is very possible you have a virus on the computer (a botnet in particular) that is chewing up your bandwidth. Botnet viruses make your computer a drone in what's called a DDoS (Distributed Denial of Service) attack on a particular website that the virus writer wants to take offline. It makes your computer (and thousands or millions of others) repeatedly send requests to this website in an attempt to overload it. It could also be used as a spambot to send thousands of 'cheap Viagra from Canadian pharmacy' ads to inboxes around the globe..

You need to figure out whether the problem is coming from the computer, the DECA connection, or the internet itself (could be slowing down due to neighborhood overload if you are on a congested cable node).

]I tried unplugging everything and then powering all items up, one at a time, but it did nothing.

We do have an error code showing up on the DVR downstairs: 71-73-705.

Now we have error code 72-697. Thanks
