SSID (Service Set Identifier) is a "business group identifier" is abbreviated, is no Routing Line network identifier used to identify a specific wireless network to the wireless devices were found on the identity. All the workstations and access points must use the same SSID can communicate with each other. SSID is a 32 bit data, the value is case sensitive. It can identify the physical location of wireless LAN, your name, company name or company name and department, a slogan and other preferences you like the characters.
2. Channel
channel is also called "band (Channel)", the wireless signal as the transmission medium is the data signal transmission channel. Wireless Broadband Router can run on many channels. Located in the vicinity of a variety of wireless network equipment to be located in different channels, or will cause signal interference. If you have only one device, then the default channel is 6 may be the most appropriate. Unless there are special reasons to change the channel (for example: interference from within the region, Bluetooth, microwave ovens, mobile phone towers, or other access point), otherwise use the factory default values. If you have more than one wireless network routers and wireless access points, it is recommended to use the channel for each device to be staggered, such as the 802.11g, 802.11b wireless standard has 11 channels, but only three non-overlapping channels (channel 1, channel 6, channel 11).
Relative to the wired networks, wireless local area network to send and receive data more vulnerable to eavesdropping. Design a complete wireless LAN system, encryption and authentication is required to consider the safety factor. Application of wireless LAN encryption technology of the most fundamental purpose is to make wireless and wired services to achieve the same level of security. For this goal, IEEE802.11 standard used WEP (Wired Equivalent Privacy: Wired Equivalent Privacy) protocol to set up a special security mechanism for traffic encryption and node authentication. It is mainly used for wireless local area network data link layer information confidential. WEP uses symmetric encryption mechanisms, data encryption and decryption use the same key and encryption algorithm. WEP encryption key (also known as WEP key) encryption for the exchange of 802.11 network, the data portion of each packet. Encryption enabled, the two 802.11 devices to communicate, you must enable encryption and have the same encryption key. WEP encryption is disabled by default, that is not encrypted. Parameter is optional wireless security settings, generally there are three parameters were as follows: (1) WEP key format: hexadecimal digital; ASCII characters. (2) WEP encryption level: disable encryption; 40 (64)-bit encryption; 128-bit encryption. The default value is Disable Encryption (encryption disabled). (3) WEP key value: set by the user. Wireless router and wireless card support encryption with each other, can be encrypted transmission of data, so that others will steal your information very difficult way. Level of WEP encryption, 40 (64) two-bit and 128-bit, 128-bit encryption is more secure. WEP key can be randomly generated a set of hexadecimal digits, or by the user to choose the ASCII characters. Normally we use the latter, by the manual input. Each wireless broadband router and wireless stations must use the same key to communication. But encryption is optional, most wireless routers default is to disable encryption. Encryption may bring the impact on transmission efficiency. To enable encryption, select the "ASCII characters" of the WEP key format, the WEP encryption method (mode), select 40 (64)-bit or 128-bit WEP key. In the use of 40 (64)-bit encryption, you can enter the four "to" different WEP key, but at the same time can only choose one to use. Each of the secret key of 10 hexadecimal characters. Stored in the wireless broadband router. In the default, select one of four key one to use. Parties in the use of 128 bit encryption, enter 26 hexadecimal characters as the WEP key. This situation can only enter a key. Some wireless network cards can only use 40 (64)-bit encryption, so you may want to choose a lower level of encryption. If all of your client be able to support 128-bit encrypted communication, select 128-bit; if the client can only support 40 (64)-bit encrypted communication, select 40 (64) bits. To enable encryption, all wireless on the network routers, access points and workstations choose encryption type and WEP key. In order to increase network security, you can always change the key. In a wireless device used to change the key, please remember to also change all the radio equipment on the network and the access point key. These are all basically the wireless router security settings, and surely we should have a comprehensive understanding of the.
