Back before Mesh and Roaming between APs was a thing I used to adjust the transmit power on my three DDWRT APs so that they didnt overlap fully to force roaming between them. I did this mostly because I didnt want too many devices on the same AP as a lot of devices back then would be stubbonly sticky to the first AP they found and APs could handle a lot less loading that they do now so it was far more important to spread devices out across the APs.
Now I still have three APs but they all WiFi 6 as are the main devices that use it so I do not bother micro managing it as WiFi 6 is much better at congestion and Roaming. I would rather have more range than worry about it, I have good coverage from the back of my garden to the front of my drive, its not essential that I have that but it is very very useful at times.
5Ghz penetrates a lot less than 2.4Ghz so that does not cause as much problems if left at 100%. 2.4Ghz can be a pain for others but I cannot wait to turn that off at some point in the future anyway.
People like Wes Streeting want to import your health care system. It’s long been the dream of people like him to do so. It’s the most valuable thing we have on the table.
