keep calm!!!
Installed in a village-hotel with around 180 rooms.
Main settings that I recommend:
1) Powers tx at 10/16 dBm,
2) Access-list reject range -120..-85
3) All powered by 48volt Poe
4) Every 4 Access points (rooms) are configured 2x 5Ghz and 2x 2.4 Ghz on different channels with Provisioning > identity regexp. Example Room1/1 "AP1", Room1/2 "AP2", Room1/3 "AP3", Room1/4 "AP4".... Room2/1 "AP1", Room2/2 "AP2", etc.
5) Importantly, before installing I reset the APs to Caps Mode, recorded all the mac addresses and softwareIDs, and assigned them by room and installed position, in excel file.
