We have a hotspot client that has dhcp+login-by-mac. The problem is that eventually they get hotspot asking for username and password.
The cause seems to be that IP changes too quick and it happens a “no more sessions allowed for this user” event.
After the old IP has been removed, the new IP doesn’t log in automatically when it should.
