So the guest get the portal page and select to accept the use policy but then it took a while to get the success - there is this loading animation.
Anyone know a trick to make it faster ?
That is actually a very good speed. During the transition to the policy or vlan that is assigned after the registration occurs, you must remember that there is a re-auth that takes place, and hence another IP Resolution process that also occurs, prior to NAC redirecting the page to whatever URL. That is a good time; some take upwards of 30 seconds. Everyone’s networks is different and if they are changing vlans that can exacerbate the delay.
