Web authentication allows DNS tunnelling

I have noticed that with only web authentication, the guest client can send DNS requests through the wireless network and out to the internet via the controller prior to being authenticated.

Then, using DNS tunnelling techniques, could surf the web, albeitly slowly, without authenticating.

Is there anyway to stop this other than turning on WPA/WEP authentication on the WLAN ?

WPA authentication is a better method of authenticatiing the clients in the network.Wi-Fi Protected Access is a standards-based, interoperable security enhancement that strongly increases the level of data protection and access control for existing and future wireless LAN systems
