radius doesn't send second request with login by mac

Hi,

I am trying to use a mikrotik 4.16 hotspot mode, sending a request to a free radius server with the computers/router mac address ( by doing Login by mac). It works fine if the computer’s mac address is in the radius database. But if it is not, and Windows 7 and its constant checking for network availability it never times out. I can put the new mac address in the radius database, but the Mikrotik Hotspot doesn’t ever send another request to the radius server, because it hasn’t timed out. I have to unplug the computer for the network for 10 minutes, or reboot the Mikrotik, and then and only then will it ask the radius server if this computer is good again. I don’t want to set the hotspot’s time out timer to 1 second, or all the computer on the network, will constantly will have to be authorized. Is there a way for setting the mikrotik to test unauthorized mac addresses, when they open a new browser window on there computer.

Thanks

When you add new MAC-address to the RADIUS server, you need to login to the HotSpot and remove the user from /ip hotspot host table, then user will be authenticated after entry is added.
