While any ISP router you get these days is liable to support the most important security protocols, such as WPA3, some third-party routers may have additional software and capabilities.

There aren't a ton of details available on Cox's website, but it's some kind of combo modem/router that combines the DOCSIS 3.0 cable modem with a 3x3 MIMO, 802.11ac Wi-Fi access point.

Cox's Elite Gamer service costs $7 per month if you have your own router and $11 per month if you rent its "Panoramic Wi-Fi Gateway." What Cox is offering is a GPN -- Gamers Private Network.

My Internet light on my router has been blinking like mad for months. I have Cox cable in Las Vegas. I had cable internet elsewhere and the light would only flash once every 5 seconds.
