I need some help as per subject line. Have an estate where +- 1500 Mikrotik units are deployed at each Apartment / Flat, 99% of these Mikrotiks are Hap Lites with the odd Hap AC2 here and there.
The problem is, some of these apartments/flats are very small, i.e. 1 bedroom units with only a single wall between the one units bedroom and the one next to it. They are also multi story buildings.
Now you getting interference from all these units around you, i.e. had a situation so bad the other day, that the person could not even connect to their own mikrotik wifi which was like 2 meters away from them. Had to reduce the WiFi channel to 20MHz, did a frequency scan and selected the least used frequency and set it to 2GHz G only and only then could the customer connect.
My question is, how can I set these routers wifi to not impact each other and is there a way to reduce the "noise / interference" from other units. My initial thinking is to run a script remotely and reduce all routers to only 20MHz channel width and only use 2GHz G only, or is there better ways for situations like these?
