I have 2 networked HR 21-200's. At least they were working fine until yesterday. I had a Belkin N1 vision router which worked ok but kept having to be rebooted lately. I decided to get an Apple airport extreme since it was dual band and had some other features i liked. Well it works fine with my 2 blu ray players and all my computers but my dvrs wont connect. It finds the network and I enter the network key but still wont connect. The dvr's are hooked up wirelessly. One using the WET610N and the other using and the other using the older linksys gaming bridge. Both had worked fine. The DVR say they are connected to the network just not the internet. Yet i cant use multi room viewing. My security is wpa2. I tried resetting both dvrs but still wont connect. i am wondering if the appple router is compatiable for this set up. I still have my old router. I think it can be used just as an access point thru the web set up just not familiar with how to hook that up. Any ideas? I am paying for the multi room set up its just not supported by DTV the way i have it.
