I'm reposting this question I asked on the Network Engineering SE, bacause I have been redirected to Super User.
I have successfully set up two Linksys routers running DD-WRTv24 to do WDS. They have the same SSID, but different static local IP addresses. There is no security: it's just for testing; no Internet connection.
When I open my notebook, I see the SSID shared by the routers in the list of WiFi access points, and I can connect to it. Once connected, I can ping both routers' local IP addresses, so I know that the WDS is working. But I can't find a way to find out which of them I have actually connected to.
I wouldn't like to have different SSIDs, because I plan to have the access points hand-off users to one another, and I want it to be transparent for the users. I configured one AP to distribute DHCP IP addresses in one range, and the other in another range, so I can discover which AP I connected to at first, but I want a way to discover which AP I'm connected to now, so that I can find out whether the hand-off actually occurred.

Check in your computer which MAC address your wifi is connected to. This is typically reported somewhere in the details about network connections. Exactly where depends on OS and version to an excessive extent for a concise answer.
Alternatively, look in the access point control software to see which one says you are attached to it.
