Wireless is the biggest reason we see for lag and disconnects. When we have problems on our side, we make an announcement about it. In order to rule out any issues with your connection, we need to go through testing.
Can you test both of your connections for me? You'll need a PC for this though. I'd like you to run a UO Trace and screenshot the results. Instructions are here. This will show us the quality of both connections and point out any issues there might be. Also, when running the wireless test, make sure your computer is as close to your console as possible. That way, the connection is replicated as much as possible.
