I just got a Genie from Directv, upgrading from my previous HD DVR. After several mishaps (my fault), I finally got it all set up and connected to my ISP, which is Comcast. And then I couldn't connect to the net with anything else: laptop, kindle, wireless DVD player that lets me access Netflix. Nothing. Except my ipad. Unless I unplugged the Genie--turning it off wasn't enough. Weird. I spent a very long time on the phone with Directv and stumped them.
The next day, I used directions from Comcast to set up Windows connection and now I can get online with the laptop, but the Genie won't connect to the internet. This is stupid. With the older DVR, I could be online with everything.
Yesterday I picked up a wireless gateway from Comcast because I think the problem could be my Motorola surfboard. I'm not sure it was even made this century. Later today I'm going to install it and hope for the best.
ETA: So far, everything is working! I'm afraid to try the DVD or printer...Let's save some excitement for midweek.
