6-1

6 Configuring Frequently Used Functions

HUAWEI HG256

User Guide

When accessing a WLAN, the user of a wireless client needs to enter the correct name of the WLAN, that is, the service set identifier (SSID) of the WLAN. Generally, the

wireless signals transmitted from a wireless router carries the SSID. The wireless adapter of a PC can find and display the SSID for selection and confirmation. Thus, manual operations for selecting andconfiguring the WLAN can be simplified. The SSID, however, is not encrypted. Therefore, anyone can find theWLAN, and then view the SSID, and the security of the WLAN is reduced.

The HG256 provides the function of hiding the SSID. After this function is enabled, the wireless signals transmitted from the HG256 do not carry the SSID. Thus, it is not possible for unauthorized people to obtain the SSID from the wireless signals. In

addition, the user of a PC needs to enter the correct SSID manually to add the PC to the WLAN. Thus, the security of the WLAN is increased.

The HG256 also provides the multi-SSID function. You can configure multiple SSIDs, and then enable one or multiple of them.

Through the multi-SSID function, multiple virtual access points of a WLAN can be

established. For a wireless client, each virtual access point can be used as a physical access point. In addition, each virtual access point has its SSID.

You can disable the SSIDs that are not required. After an SSID is disabled, a wireless client cannot connect to the WLAN that is indicated by this SSID. Note that all the external connection channels of a WLAN are closed if all the SSIDs of the WLAN are disabled. To use the WLAN, you need to enable the WLAN function and at least one SSID. In addition, to use the WPS function, you should enable SSID1.

Configuration Example

To use and hide SSID1 and disable the other SSIDs (so that the WLAN cannot be found by others), do as follows:

Step 1 Log in to the Web-based configuration utility. Step 2 In the navigation tree, choose Basic > WLAN.

The WLAN configuration page is displayed.

Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Step 9

Step 1 Log in to the Web-based configuration utility. Step 2 In the navigation tree, choose Basic > WLAN.

The WLAN configuration page is displayed.

Step 3 Select SSID1 for SSID Index. Step 4 In SSID, enter MyNewSSID. Step 5 Click Submit.

----End

6.2.3 Using Secure Encryption

Function Overview

To ensure the security of a WLAN, an important solution is to select an optimum security mode for the WLAN. After this security mode is used, a wireless client should provide the corresponding password when connecting to the WLAN and data is being

transmitted after secure encryption. Thus, only authorized persons can use the WLAN and the data transmitted on the WLAN is protected against unauthorized access.

The HG256 supports WEP encryption and multiple security modes, such as WPA-PSK and WPA2-PSK, thus meeting security requirements in diversified network environments.

It is recommended that you set the security mode to WPA-PSK/WPA2-PSK and the encryption mode to AES. Thus, the WLAN works efficiently and the security of the
