You complain that I am using a 3rd party WiFi to extend my nework. But I already tried the Comcast in-network solutions to extending my WiFi netork to reach all the devices. The Comcast solutions to network extention simply DO NOT WORK.
The Comcast solutions to WiFi network extension have the following critical problems. So please do not complain that I am using 3rd party solutions that DO work well.
1. When I use Comcast WiFi network solutions, it reduces my WiFi nework speed by about 4-fold, from a gigibit speed to less to 200 MB speed. Since network speed is my primary concern, this was unacceptable.
2. Comcast WiFi newtwork solutions are unreliable. They force my devices to connect to the wrong access point consitently. When I was using Comcast XFi extenders I had to shut the extention down numerous times to correct rogue network connections.
Furthermore, the fact that Comcast cannot report on devices correctly has been occurring long before I added a 3rd party WiFi extension. I've had to replace my Comcast modem more than twice in the last year because not only reporting failures, but modem software failues where authorized devices were unable to connect.
I suggest that you stop blaming me for using 3rd party extensions and instead spend some money on improving Comcast systems.

Please note that this is not an issue that is connected to a single device. It can happen with any device which is capable of connecting in multiple ways.
There are three ways to connect to the internet in my configuration:
1. My computers connect via RJ45 wiring directly - ethernet proper
2. The Technicolor Modem has 5ghz and 2.4ghz (separate) bands (call them A and
3. I have, in addition, an additional add-on WiFi system which is plugged into an eithernet port; that system also has 5ghz and 2.4ghz bands and is capable ot the same speeds as those offered by the Technicolor modem. (call these two bands C and D)
So a device can connect to Ethernet, or any of the A, B , C or D WiFi bands. This configuration has some issues that i would like to solve, but it works for me. Since my house wired for Ethernet RJ45, the C and D bands are on the other side of the house from the A and B bands solving a problem I had with dropped connections from some smart devices.
Here are some of the complicating issues.
1. The C and D bands are not capable of the same level of security as the A and B bands. I only installed them after having serious issues with multiple Comcast solutions of extending WiFi coverage. Comcast solutions were difficutl to control, and reduced the internete speed by a factor of about 4.
2. The Technicolor modem from comcast does not recognize the C an D bands as WiFi nor can it see the bands. So a device that connects to C or D WiFi is reported as an "Ethernet" connection by XFi, the Comcast Online system, and the local cable modem menus. The device knows it's connected to C or D WiFi but your system records the connection as "Ethernet".

I have encountered the following persistent issues with multiple Comcast cable modems. Is it just me?
1. Some of my devices which connect over WiFi are reported as disconnected even when it can be demonstrated that they are connected.
2. Some advanced security features work after first setup for a while - but as soon as an unknown sufficient number of changes are made in the settings for those features, they stop working, refusing to allow authorized devices to connect, and the only way to fix those features appears to be to replace the Cable Modem.
3. XFi doesn't help, since it seems to agree with the false information on the Cable Modem on everything.
