--> Recently I faced this problem where some client users were unable to get Cisco Wireless Lan Controller Web Authentication redirection page when they connected to wireless network.
--> You can get this problem due to so many reasons, such as
i) Wireless LAN Controller Fails to perform Domain Lookup.
ii) Internal DNS Server is not configured.
iii) Incorrect DNS domain under Virtual IP address in WLC.
iv) Check the DNS is mapping the same domain name that you set under the virtual interface configuration with the IP address 1.1.1.1.
v) Check if the client gets an IP address. If not, users can uncheck DHCP Required on the WLAN and give the wireless client a static IP address.
vi) Disable the Windows firewall before you try to access the login page. The firewall can be enabled again once the web authentication is completed.
vii) Check the user proxy settings.
viii) By default, Web authentication starts when the controller intercepts the first TCP HTTP (port 80) GET packet from the client. If you want the Web Authentication to start with HTTPS Packets as most of the websites( Google) are HTTPS then configure the following command by using WLC CLI.
(WLC)>config wlan security web-auth enable 10
(WLC)>config network web-auth https-redirect enable
