I currently have a new Netgear 3.1 Modem and Netgear Nighthawk 7800 Router which are both powerful and expensive. I have tried 3 different modems and 4 routers over the last 20 years. My 5Gz is now 175 Mbps but has limited range about 40' so I use 2 Netgear Wifi Range Exteneders to use it for my 4 ROKU powered TV's. My 2.4Gz was 68 out to 75' but has dropped to 10 Mbps since Christmas and still there. The yearly massive influx of FL Snowbirds which starts around Labor Day is the reason for the 2.4Gz drop for the last 20 years. Comcast should do something abou the slow 2.4Gz speed problem instead of blaming users poor equipment. The equipment is not the problem. I was told Xfinity is supposed to switch to 3.1 Docs starting in about June of 2019. That should help I think. A comcast repairman told me that there is a AM radio station in Punta Gorda that can interfere with the 2.4Gz network, I am very disatisfied about Comcast 2.4Gz poor performance and should not have to add two Netgear Wifi Extenders to get 50 to 75' range with the modem and routetr I am using. User equipment is not the problem. Comcasts failure to use Firber Optic cables instead of outdated wired trunk lines to deliver our internet service are the problem along with the fact that the entire internet sytem is wired in series instead of parallel which means the more users on your trunk line or street the slower the interent speeds. I was told about this problem by a Comcast repairman 15 years ago. Comcast does use some firber optic cables but has to rewire the entire user internet system using them.. Until then we will have to live with this slow 2.4Gz poblem.
