For comrades whose pings hang and grow and the network completely falls down, this is dedicated! Well, firstly: so that pings do not grow, the network (in which your access points are located) is not hung up. Isolate wireless clients - this is the second time: be sure to include access points in a managed switch and isolate ports! Why this is needed, I briefly tell why and what happens, when a client connects to one access point, its mas address is automatically registered there, then suddenly this client jumps to the second access point, and leaves its mac address there, what happens, when he (more precisely, his device) sends packets, they arrive at some kind of switch, the so-called ARP table (table of mas-addresses by ports) is cached on the switch, and so, when the same mas-address is "lit" on your switch, and even more so on several ports, then when sending packets, this switch begins to misunderstand, but where to actually send them, and it turns out, then the client is at point-1 then at point-2, some especially advanced wi-fi cards generally know how and can connect to several points at the same time! And the mas-addresses of the connected clients on the point are not reset immediately! some time passes, because of this, the so-called arp-storm rises in your network, read about the OSI model. In general, you do not hang a point, but a SWITCH ! from that and the brakes and the growth of pings . and I'm 10000000% sure that all your points are plugged into an unmanaged switch, and besides, the whole network is configured incorrectly in general ! At my work, this is a large facility (hotel), several buildings and floors, these TP-Links hang every 15-20 meters (for perfect coverage everywhere and in all rooms). Everything is great and works great! uptimes since January 2022, now it's the middle of July, and NEVER ONE has hung or cut down! In addition, the entire network is seamless! . well, the good old 2022 server is responsible for the operation of the entire network and points in general (dhcp dns http and authorization in Wi-Fi (the law was invented after all . )
