I sure lose the icon a lot these days

With 3.21.329 and Vista SP1 it vanishes on ~ daily basis. When I go to look at something in CFP, need to restart the GUI from the shortcut. Was never a problem previously. Also notice more connection problems. Lose internet connection (wired) and need to restart the router to get it back, even though router has a proper WAN IP and computer has a proper LAN IP. Again not a problem previously. Anyone else having similar problems? ???
