How to connect China Mobile broadband to wireless router

The steps are as follows:

1. Please link the device as shown in the figure below. Power is the power supply, (1, 2, 3, 4) lan is the output port, and wan is the network cable insertion Port and reset are the reset keys (hold a sharp object for 5 seconds when resetting)

2. After the connection is completed, check the operating status of the indicator light: the sys system status indicator light should be flashing, 1 /2/3/4 The LAN status indicator light corresponding to the computer lan port should be steady on or flashing rapidly, and the wan Internet status indicator light should be steady on or flashing rapidly.

3. Set up the computer, right-click to open the local connection>Properties, double-click "Internet Protocol (TCP/IP)" and select to automatically obtain an IP and DNS address

4. Set up the router and open the web page (Browser), enter 192.168.1.1 in the URL bar, (the address of some routers may be 192.168.0.1, see the bottom of the router for details)

5. Click the setup wizard on the left, next step

6. For broadband dial-up settings without router, first double-click the broadband connection, and then enter the account number and password in the box

Wireless settings

1 ． SSID

SSID (Service Set Identifier) ??is the abbreviation of "Service Set Identifier". It is an identifier of a wireless network and is used to identify the identity of wireless devices discovered on a specific wireless network. All workstations and access points must use the same SSID to communicate with each other. SSID is a 32-bit data, and its value is case-sensitive. It can be the physical location identifier of the wireless LAN, your name, company name, or company name and department, preferred slogan, etc., but if the setting is not in English, garbled characters will be displayed on some devices, or connection failure will occur. on the problem.

2． Channel

Channel is also called "Channel", which is a data signal transmission channel that uses wireless signals as the transmission medium. Wireless broadband routers can operate on many channels. Various wireless network devices located in close proximity must be on different channels, otherwise signal interference will occur. If you only have one device, then the default channel value of 6 is probably best.

Unless there is a special reason to change the channel (such as interference from Bluetooth, microwave ovens, mobile phone towers, or other access points in the area), please use the factory default value. If you have multiple wireless routers and wireless access points on the network, it is recommended to stagger the channels used by each device. For example, the 802.11g and 802.11b wireless standards have 11 channels, but only 3 are non-overlapping channels (channel 1 , channel 6, channel 11).

Wireless Router Security Settings

Compared with wired networks, data sent and received through wireless LAN is more likely to be eavesdropped. When designing a complete wireless LAN system, encryption and authentication are security factors that need to be considered. The most fundamental purpose of applying encryption technology in wireless LAN is to enable wireless services to achieve the same security level as wired services. To achieve this goal, the IEEE802.11 standard adopts the WEP (Wired Equivalent Privacy) protocol to set up a special security mechanism to encrypt business flows and authenticate nodes.

It is mainly used to keep the link layer information data confidential in wireless LAN. WEP uses a symmetric encryption mechanism, and the same key and encryption algorithm are used for data encryption and decryption. WEP uses encryption keys (also called WEP keys) to encrypt the data portion of every packet exchanged on an 802.11 network. When encryption is enabled, for two 802.11 devices to communicate, they must have encryption enabled and have the same encryption key. WEP encryption is disabled by default, which means no encryption. Wireless security parameters are optional settings. There are generally three parameters, as follows:

⑴WEP key format: hexadecimal digits; ASCII characters.

⑵WEP encryption level: disable encryption function; 40 (64) bit encryption; 128 bit encryption. The default value is Disable Encryption.

⑶WEP key value: set by the user.

Wireless routers and wireless network cards that support encryption function work together to encrypt data

transmission, making it difficult for others to steal your information midway. There are two WEP encryption levels: 40 (64) bit and 128 bit. Using 128 bit encryption is more secure. The WEP key can be a randomly generated set of hexadecimal numbers, or a user-selected ASCII character. In general, we choose the latter and input it manually. Each wireless broadband router and wireless workstation must use the same key to communicate. But encryption is optional, and most wireless routers disable encryption by default. Encryption may have an impact on transmission efficiency.

To enable encryption, please select the WEP key format of "ASCII characters" and select 40 (64) bit or 128 bit WEP key under WEP encryption method (mode). When using the 40 (64)-bit encryption method, you can enter four "different" WEP keys, but you can only choose one to use at the same time. Each key consists of 10 hexadecimal characters. Saved in wireless broadband router. By default, one of the four keys is selected for use. When using the 128-bit encryption party, enter 26 hexadecimal characters as the WEP key.
