Wireless Access Point
User Guide
The AP supports various security modes for network encryption, including None, WEP,
WPA-PSK, WPA2-PSK, Mixed WPA/WPA2-PSK, WPA, and WPA2.
None
It indicates that any wireless device can connect to the WiFi network. This option is not
recommended because it leads to network insecurity.
WEP
It uses a static key to encrypt all exchanged data, and ensures that a WLAN has the same
level of security as a wired LAN. However, data encrypted based on WEP can be easily
cracked. In addition, WEP supports a maximum WiFi network throughput of only 54 Mbps.
Therefore, this security mode is not recommended.
WPA-PSK, WPA2-PSK, and Mixed WPA/WPA2-PSK
They belong to pre-shared key or personal key modes, where Mixed WPA/WPA2-PSK
supports both WPA-PSK and WPA2-PSK.
WPA-PSK, WPA2-PSK, and Mixed WPA/WPA2-PSK adopt a pre-shared key for authentication,
while the AP generates another key for data encryption. This prevents the vulnerability
caused by static WEP keys, and makes the three security modes suitable for ensuring
security of home WiFi networks. Nevertheless, because the initial pre-shared key for
authentication is manually set and all devices use the same key to connect to the same AP,
the key may be disclosed unexpectedly. This makes the security modes not suitable for
scenarios where high security is required.
WPA and WPA2
To address the key management weakness of WPA-PSK and WPA2-PSK, the WiFi Alliance
puts forward WPA and WPA2, which use 802.1x to authenticate devices and generate data
encryption–oriented root keys. WPA and WPA2 use the root keys to replace the pre-shared
keys that set manually, but adopt the same encryption process as WPA-PSK and WPA2-PSK.
WPA and WPA2 uses 802.1x to authenticate devices and the login information of a device is
managed by the device. This effectively reduces the probability of information leakage. In
addition, each time a device connects to an AP that adopts the WPA or WPA2 security mode,
the RADIUS server generates a data encryption key and assigns it to the device, which makes
it difficult for attackers to obtain the key. These features of WPA and WPA2 security modes
help increase network security significantly, making WPA and WPA2 the preferred security
modes of WiFi networks that require high security.
7.1.2 Changing the SSID settings
To change the SSID settings, perform the following procedure:
1. Choose Wireless Settings > SSID Settings.
2. Click a tag page as required, which is 2.4 GHz SSID Settings in this example.
3. Select the SSID from the SSID drop-down list box.
4. Change the parameters as required. Generally, you only need to set the SSID, and
Security Mode, Key parameters.
