Yeah, very similar issues. We "upgraded" from 211Z to Wally and have had these issues.
We went through two Wallys, new cable, and two X2's. We could never go more than a few hours without signal loss issues. Sometimes we'd go through the acquisition process and end up with NO usable channels. This on both East and West sets of satellites. Sometimes the Wally would report no satellites found after about 30 seconds... without moving the antenna at all. Often we'd get SD but no HD. Once it lost signal it would never find it again without going through the whole acquisition process again. Very frustrating and time consuming.
We finally had to revert back to the 211 and have had no issues for the past two months... despite foul weather.
I really like the UI, remote etc for the Wally, but they simply do not work reliably, despite Dish selling them as a package.
Not happy with the Wally or with Dish for this... and I have been a loyal Dish customer for many, many years.
I have similar problems with the Wally. I have the Wally and the 211Z and the Dish Tailgater and the King Tailgater. The Wally fails to find satellites and the 211Z on a different dish finds them just find. I can switch the cables to change the receivers and swap the dish receiver connection. The Wally still fails to find satellites on the second dish and the 211Z finds them just fine on the first dish. In my opinion, the Wally is garbage.
