I’m trying to identify if any two devices at the time are connected to same wifi connection (router)? For this I’m trying to leverage three parameters - BSSID, SSID and public IP Address but there can be many cases in which all three informations can be different but still the WiFi connection is same.
e.g.
- Both the devices are connected to different bandwidth connections from same router and thus this will provide us different SSID and BSSID with same IP.
- Now over the above case consider first device connected to VPN connection thus the IP will also change for that device.
I went through a similar question and here it is suggested to use the first 4 Bytes of the BSSIDs from each connection and that will be same for each connection but I'm not sure how feasible is that as later in the comments it is mentioned that there can be cases where different routers can too have those same 4 starting bytes.
Let me know if there is any other method/way which can be helpful?
