When I use this tool, wifiinfoview - by nirsoft.net, I can see alot of information about the wifi access point cAP ac.
Shows company, router model, router indentify.
(dont get me wrong, I like to promote mikrotik, but not this way 
)
How can I hide this information from other people scanning the network neighborhood.
Disable (if active) SNMP, use random MAC address on wireless interface and all other CPE interfaces, disable neigbor discovery on that interface,
block forever on firewall raw, and on wireless access list, all MAC than try to scan the network…
All wifi AP’s distribute this information 10 times per second in their AP beacon.
WifiinfoView even only is able to express some fields in a readable form. There is much more.
WifiinfoView is one of those “free” monitoring tools, and I’m using Netspot and inSSIDer. (They come and go, once free, later with license … https://www.pcwdld.com/wifi-tools)
If you would use inSIDDer and export the summary (of all received beacons) it then can be fully analysed with Wireshark to the latest bit.
Besides hidding the SSID, there is no parameter to suppress that information.
