Okay, I just changed my router to a Linksys N instead of the the old WRT54g that served me so well for years and I set up my 18' Acer laptop and my 15 inch laptop and noticed that after they were up and running and I rebooted the small Acer 5100 x86 it had a normal tray icon (step bars) but there was a blue dot with what appears to be an initial of some sort in the middle of the blue dot that is on top of the tray icon. I have wireless with WPA2 encryption, but I have never seen that icon once I was up and running. It usually rolls in windows 7 and stops and reverts to either normal if it's hooked up or it keeps spinning. Anyone have a clue??
