Okay, now that I'm up and running I thought I'd share my install experience. I came home at lunch to see if there was an early delivery. Sure was! I brought it in and started to unhook my HR20 in the living room. The first thing I noticed was I needed to unclip my zip-ties so I could remove my antenna cable. Aside from that, looking at the back of the HR21 the coax connectors seem to be a little longer than the HR20s. I got everything hooked up and I was ready to go. Sure enough once it fired up all of the channels with the exception of the locals were active. I logged into the DIRECTV site to shoot a refresh and life was good. I also went into the dish setup and changed it from 3 LNB to 5 LNB. A few more minor tweaks (resolution, pillar box color, etc.) and I was in business. Initial reaction was very pleasing. Time for the networking.... I pulled the MAC from the HR21 and added it to my filter list on my router. I set the IP on the HR21 and tested. No joy. I had network but no internet. I rebooted my router and replaced my wireless adapter with a known good. Still nothing. I was on my lunch break so I had to run for a while. I came back from work early *cough* and got back to setting up. I tried to set the network defaults and the box froze. I rebooted and tried again. It looked as it worked but when I went into advanced there was still some residue of an old static address. It's a new box so I ran a C&D (much faster than the TiVos!). The yellow record light was stuck on and still no joy with the networking. Another reboot. I finally decided to troubleshoot from the router out. First thing I did was kill MAC filtering and the darn thing lit up like a Christmas tree. I'm not sure if I have the wrong MAC address being shown to me from the receiver or not. I just know when I turn on "Enable the following" it goes away. Other than that it was pretty straight forward and I'm up and running. I need to still filter my channels and let the guide data populate so I can set up my Series Links but other than that I think we're in business. How did everybody else's installs go?
