Do answer one of the original questions, if your sling adapter is the red waffle looking one from Dish, it only has ONE red light and your tech was mistaken. In my home I use a IPTV Sling link for my 722Ks internet connection however that should work similarly to your device. I would, for experimentation's sake, run a long cat5 cable from your router to your 722. If it works better, consider finding a more attractive way to run said wire. I have a 12mb connection from Charter internet and I can watch TV over 3G (albeit choppy) on my phone and the Mrs uses it on her iPad via her work's wifi.
