The low price surge protectors like Furman I plug tvs into and router
if Anyone has a seperate modem to router get rid of it ,outdated technologies
I had a older spectrum setup wall warts Suck !
I bought a Motorola 8702 combo it has the newer docsis 3.1 much bigger processor bigger buffer wifi range and picture on tv better , I put a Good 12 volt Linear Power supply on the router it made a very nice improvement in streaming sonics , from Linear Tube Audio , by far the best LPS under $1200, for $750 a steal
I compared with 5 other well known brands inside everything is far better if you are serious look no further ,mine is good up to 8 amps, they can build up to 20 volt units ,maybe more.
