There should be a way to change WiFi channel, or at least the system should change it by itself, choosing the least saturated one. For 2.4GHz it is clear that it will be almost impossible to select a free channel, but on the 5GHz I only see other 2 networks and we are all in the same channel! For at least one the reason may be that our neighboor is using a TP-Link product as well.

I think this is a very basic configuration in any WiFi device, which I would have never though was not going to be possible before buying it.
