WEB INTERFACE PART 2
How many times have you tried logging into the WiFi of a cafeteria or a hotel only to be redirected to a website asking for your information? This is basically what the captive portal sub-tab does.
You can add access control list rules and associations from within the ACL sub-tab while the cluster feature (single control over all connected access points) can be adjusted from the cluster sub-tab.
As expected from the maintenance tab you can perform firmware updates, copy/save and backup/restore the current device configuration, reset all settings to their factory defaults, reboot the access point and perform diagnostics.
