Have a setup which is using Guest Registration External Captive portal to ExtremeControl, with text based verification via XCC.
What happens is the client registers through the captive portal, which the process completes without issue, but the client never moves to the authenticated role.
In this case the client was asked to disconnect and reconnect, but took a forced disassociate from XCC to get the client to re-auth and get the correct role / VLAN / subnet (172.16.x.x) in order to connect. This issue seems to be more related to the desktop / laptop rather then when using a phone.
So the transition of registering isn't as fluid as might be expected
I believe COA is enabled by default, but in this situation it might need to be turned off based on the is article due to the VLAN change?
