A:Answer Well, my TV and WiFi and connected directly to the two Ethernet ports on the Modem. The Linksys WRT WiFi router can support 4 more somethings plugged in the Ethernet ports, and then multiple WiFi enabled devices at the same time with no loss in speed. When my sister and the kids show up there are 6 twenty and thirty-something’s on phones and tablets, two 10 year olds gaming, and usually a few of us old folks on laptops and tablets and it all works fine. Supposed to be 5 GHz , I can’t measure that but nothing has ever been slow.
