Model : Hardware Version : Firmware Version : ISP : Hi there, i'm actually in testing AC50 with some CAP1750. There are some SSIDs which are connected to some VLAN (one VLAN per SSID) - this works fine. Now I've set up an voucher-authentication with splash screen for one SSID/VLAN and created some vouchers (valid 24 hours, single user), also I've activated non-sense-authentication. The problem: When a client logs in with voucher, everything is okay, log in works, validity is shown correct. But when the client leaves the network for some time (lets say 20 minutes or so), after reconnect the splash screen is shown again, the device is not logged in automaticly. Furthermore, the voucher is marked as expired and cannot be used anymore, even the time ist not expired at all. This means: A 24h-voucher can only be used that time when the Client is not disconnected. If so, the user Needs another voucher, even whe uing the same device and within the 24 hours. This seems to be not okay so?! Hopefully somone a help with his issue?! With kind regards, jcvmaster
