Security
The Security function protects your wireless network from invasion. We provide WEP
and WPA encryptions to secure your wireless network.
If you select “Disable” to close the Security function, any client can access the router
without password and any data will be transmitted without encryption. We strongly
recommend do not do that.
Before setting the encryption, please check the SSID (See the setting in Wireless >
Basic Settings) in the “Select SSID” drop-down list if you set multiple APs.
The Web interfaces will display differently in each working mode.
