Is it a Cablevision you have?

Well, all telco providers here give Internet (up to 1G), phone, TV, wifi, router etc. in 1 box. The router works fine, for the wifi, I use an Airport Extreme which is far better.

They mention 4K cable box, but it is mainly HD TV (1080p) there are so few 4K programs or channels that is is only marketing.
