After upgrading to to 3.0RC9 my routerboard 532, which is running a hotspot on the wireless and also running the User Manager system, now refuses to authenticate hotspot users via radius. I keep getting a RADIUS server timeout message. It was working perfectly before the upgrade. I tried removing the Radius entry and re-adding it, but this did not solve anything.
please look in the debug logs in the radius client and in the user manager, what error message does it give?
Make the support output file right after you try to connect to the radius server and it fails, then email it to support@mikrotik.com
