This thing was driving me nuts, constantly dropping connections for no obvious reason. Would work fine for a day, then would be complete crap the next. Had fun with this thing for an entire week. Would only get 3 bars and the Router was right down the hall, in direct line of sight!! Swapped out the Antenna with one WIFI adapter that came with a Zotec Motherboard. The Antenna is barely an inch long. Screwed it on to the Blue Port. Wasn't sure if it's just a Dual Band antenna or the red is some sort of power connection? Get all five bars and it hasn't dropped connection yet. Still not sure what the difference is between the Red and Blue. Can't find anything online to tell me. Any technical baggers know?
