I have been using a Belkin fsd7630 for two years with no probs but recently the LED indicating data line active keeps going out. A simple repower always puts it back on and it seems to stay on as long as I am connected to the net. The major inconvenience is having to run up and down stairs to switch the router off and on. Scoured Belkins web site and found no clues. Any advice on where to start looking for a cause and remedy would be helped.
