For the last ten years my wife and I have been using a Linksys wireless cable gateway. We have Comcast cable internet and the old modem is getting tired as well as not being optimal for the fastest speeds. We are running more stuff on it now than we did then. Two laptops, a desktop ItalkBB, Netflix, Dish world, an Airave that gives me WiFi calling for my cellphone as well as our two cell phones WiFi. I use up all four of the Ethernet plugs. So what do all you technophiles recommend I get to replace my old one. I like the convenience of a modem router combo but is it the best for my needs? Carl
