Q: My Internet connection, which I get through my cable company, has been intermittently dying on me, but my television works fine. As in winding it too tightly and causing distortion. Help. He did the signal strength test before and after and it really helped. In fact, in most cable networks, Internet transmissions are sent over a single 6-MHz band--the same amount of spectrum allocated to an individual cable TV channel, and just one of the hundreds of similar-capacity bands on the wire. Coaxial cable carries radio frequency signals. Signal Problems when Coaxial Cable Shield is connected ? There are several possible causes of your Internet outages. If that distortion is severe enough, the center conductor will 'migrate' to the side and eventually short to the braid.

You may want to get a new modem, router, or network card to see if any of those devices are causing the problem. Today’s coaxial connectors have to be high-performance and provide nearly flawless signal transmission to accommodate the very large amounts of traffic … The term "coaxial" refers to the inner conductor and the outer shield sharing a geometric axis. Coaxial cable loss is normally specified in dB loss per 100 feet of cable. The longer the length of a piece of coaxial cable, the more signal is lost. A: It's fair to conclude that you don't have an overall connectivity problem, since your cable Internet runs over the same coaxial (and sometimes fiberoptic) network that your TV signals use. Remember to tighten the cables on both splitter and TVs by gently screwing in the caps to the connectors. So that takes out a lot of the overhead interference.
