I used a microwave link to get my internet service, I have for about 4 years. As many of you have read in posts in this forum I have been having pixelation problems ever since I upgraded to a 722 from my 622 about three weeks ago. The problem was very apparent with the 2nd 722 as the first one only lasted about 3 hours till the hard drive died. Dish has been out to address this pixelation problem without very much success. They have replaced my two dishes (one with a dual lnb for 110 & 119 and a 24" dish for 129) with a new DISH 1000. A few day later they moved the new dish west about five feet and they replaced the coax from the dish to the receiver. I am still having the same amount of pixelation. The lead tech tells me that the microwave signal that I receive my internet on is intersecting with the dish signal, now they want to move the dish again, this time about 60 feet east. (all locations used have complete clear sky with no obstructions what so ever. I have spoken to my internet provider and have been told that the Dish signal and the microwave signal are so far apart on the spectrum there is no way one could/should interfere with the other. The majority of my problems are on tuner 2, tuner 1 seems to have very little or no pixelation at all. Does anybody have the facts on the possibility of microwave interference in a installation like this?
