Wifi – How to detect a WiFi Repeater on the network

If a satellite link is somewhere in the picture, even bad wifi links come no where near the 550-600ms due to the satelite hop. So what if you add 10-50ms with some repeaters.

I dont have much experience with low end "wifi" but stuff like mikrotik we can do 2-4 hops, each 8km and the latency stays 10-20ms with low load. But that is a good one. On our bad ones (alvarion old stuff) with several hops is can be 100ms over 16km when loaded. But i have seen people connect offices with wifi links and dont notice a difference browsing. You might have more jitter with VoIP.

equipment that uses frequency hopping as opposed to Direct Sequence has higher latency. I dont think FH is used much anymore.

If loads are high latency goes up.

Some DSL modems will work back to back, might be an option for you. wires are easier to troubleshoot in congested areas.

If your switch (or more accurately the client's switch) is capable of filtering the multicast packets by address (blocking the multicast prefix) that would be my first suggestion.

Barring that you can put a simple filter device (firewall) between the WAP and the main network that just drops any packets to/from the multicast address range...
