I singnet, just recontracted 3 mths ago with no problems at
all... If its not your modem's fault, then its either your wire,
your com or the land line's fault...
x2
My Singnet used to go off too and we got the technician over
because it just goes off for no reason
In the end the problem was found to be caused by my modem
wire
After changing wires there were no longer any problems
