My router started giving me problems with dropping signals for the last week, week and a half. Tried a direct plug and it would wipe out all of a sudden. knew TW was working up the street. Called them. Someone had done something to our line in installing cable to the apartments next door...they rewired on it on Sunday morning for me, and on the ping test said something was still irregular with our feed into the house. Tech came today, and we discovered part of the problem was the cord going from my splitter to the modem was failing. I needed a shorter one anyway because a long cord will cause "bleeding" of your speed, etc. On a long line. He made me a short cable because you can't buy them that short and checked my feed and gave me an updated splitter....it was just one little cable causing some of my problems. So maybe you should check that. I have a TV tuner on my CPU so I can watch TV there should I want. You have to split the cable, one side for TV tuner, the other to the router. No more drops and speed is back up to what it should be. AND didn't charge me.
