Hi,
We should first check if the vlan used for the CP network is routable.
For that, please try the following steps:
1. Connect the client to the guest network.
2. Run the following command to put the client in to authenticated role.
Aruba# aaa user add <ip-address of client> role authenticated
The role authenticated has a allow-all ACL inside it. So, the client device should be able to browse out to internet .
If the client device is unable to browse to internet , then there is an issue with the DNS or routability of the vlan which needs to be corrected which is in turn causing the CP page not to show up automatically.
Along with that, please paste the output for the ACL's mapped to the actual role that gets assigned to the client
when it initially connected to the guest network.
Aruba# show rights <name of role>
