WiFi

You are welcome. Don't forget to ensure your new mesh router is set up and working before shutting down your TELMEX radios. In fact if your channels are not congested where you live, you actually can have both radios on along with your new mesh equipment, assuming there is channel selection option on your new equipment which should minimize any cross interfearance. You should also have the option to do channel selection on the TELMEX radios and you can set them to a channel not utilized on one side of the band and the new mesh router and satellite on a channel not utilized on the other side of the band. With this, you could also extend the Ethernet cable you plan to run from your TELMEX router to the main mesh network router to where the main mesh router is in another part of the home from the TELMEX if it was possible to locate the other satellite in a line of sight of the first it would be good, plus locate the satellite router even further where there are no obstructions between the two (glass is OK) routers other than distance if at all possible.

There are phone apps to do wifi network scans and you can normally scan and make notes at your location and thus check out the channels the neighbors are using. Most will probably be using channel 11 or 1 perhaps but it varies. So let's say you find multiples of signals on all the channels perhaps with the exception that channel 2 is open and channel 10 is open. You could change the TELMEX 2.4GHz radio specifying channel 10 (the unused one) and the 5GHz likely won't matter because few people are using this band but you can also be safe and tune that to an unused channel in the neighborhood as well seen by scanning the 5GHz band. Now getting back to the more utilized 2.4GHz band you can go into the mesh routers configuration and configure them to use channel 2, the other channel as far channel-wise from the TELMEX as you can find.

In most areas you do not have the serious contention for channels that we have in this fish bowl parabola of GTO and you will never see the types of channel contention going on here, adjusting channels in this environment can provide you a better chance of not having interference in your home if you can get away from the channels your neighbors are using. This is something that needs to be checked periodically and re-tuned as people come and go near you, adding and removing services, routers and doing their own channel tuning.

Note: Many routers supposedly do an initial scan to find an empty or underutilized channel but I have never seen one to date that was actually using a good low utilized one that is seen with actual network scans. So what you can do is leave both networks on the AUTO selection for channel, then follow up with a smartphone network scan and see if they are playing by the rules. If they are automatically switched to low utilization channels (as proven with your smartphone scan), then all is well and you can forget this aspect of configuration. However if you find them on the exact same or right next to each other channel-wise or on top of your neighbors channels, then you will gain by customizing the channels they are assigned, setting them manually.
