We have a Dell Networking W-650 controller running ArubaOS 6.4.0.1 We reset the password for guest wireless access and then lost the Captive Portal. Now, you can connect to the guest network, but the connection remains at connected/no internet access because we can no longer authenticate to the guest wireless network due to the Captive Portal no longer showing up.
We have tried rebooting, changing the password back, but still cannot get the Captive Portal page to appear.
