I was able to setup mine last night. Although I have a Buffalo router running a version of DD-WRT so I had to locate where the settings need to be since D*TV didn't have the screen shots for me. I'll post mine here so maybe would help anyone else running DD-WRT... took a router reboot and a few extra minutes for GenieGo app to start working properly. Going to test everything is workingn properly out of home later today.
I also have a Buffalo router--an older G version---and the Genie PC app found the router and opened the ports without problem.
It seems to be working on laptop, iPad and iPhone, although I had to delete and reinstall the app on the latter. It was stuck on loading content, and the problem repeated even after rebooting the phone. Reinstall fixed it.
Haven't had a chance to check it on wifi outside the house yet. I have a strange craving for Starbucks today.
