Some people .. including myself have gone through such experiences. It generally lasts from a few days to a week. If any longer then perhaps need to look at some kind of change. Such changes I refer to are a couple possibilities I can think of. (1) going to connections window, remove longest connects Ultrapeer, choose remove. Wait a few mins depending on how long it takes to get a replacement ultrapeer & a stable connection. Try search again, if still no good then repeat process.
