Our internet was getting slower and slower. It got to the point where if I was on my laptop via wireless router, and hubby got on the desk top, it knocked me off, then we could not get on at all. Ran test, talked to Internet tech support team, it would come and go, hubby suddenly got an idea, he unhooked all the TV's from the main cable coming in and the internet flew like Super man, He then called the cable company and they agreed with him the splitter must have a short in it, they told him to come by and they gave him a new one, its been fine since. :heartlove
