I've personally been through 4-5 "gateways" with Comcast in about 6 months. Service into home has always tested fine. While they are either Arris or Cisco, they look identical and most now do have dual band Wi-Fi. But $11 a month and tomorrow replacing yet another one until I can purchase my own. Mass produced pieces of crap that obviously were chosen due to lowest bid. Renter of equipment from any cable company beware.
