Wireless encryption protocol (WEP) is a standard method to encrypt the data transmitted in wireless network. Now most of the wireless devices only have WEP encryption, more secure WPA encryption has not been widely used.

At present, there are two key types of wireless router or AP. For example, the use of wireless routers will have 64 and 128 of the encryption type, respectively, 10 or 26 to enter the string as a password.

Here to remind you that many wireless router or AP in the factory, the data encryption transmission functions is closed. If you bring with and without setting further, then your wireless network became the a defenseless furnishings. Therefore, it is extremely important to encrypt the settings for your wireless network.

Two, disable SSID broadcast

In layman's way, SSID is the name you give to your wireless network. Need to pay attention to is that the same manufacturer launched a wireless router or AP use the same SSID, once those illegally trying to connect the attackers use generic initialization string to connect to a wireless network, easily established a illegal connection to our non line network threat. Therefore, it is recommended that you are better able to name SSID some of the more personal names.

Wireless router will generally provide "allow SSID broadcast" function. If you don't want your wireless network to be SSID by someone else, it's better to "ban SSID radio". Your wireless network can still be used, but it does not appear in the list of available web sites that other people are searching for.

Tip: after the ban on SSID radio set, the efficiency of the wireless network will be a certain impact, but in exchange for the security of the increase, that is worth the.

Three, disable DHCP

DHCP function in the wireless LAN automatically for each computer to assign IP address, do not need to set the IP address, subnet mask and other TCP/IP parameters. If DHCP enabled, it is easy for others to use your wireless network. Therefore, it is necessary to disable the DHCP function for wireless networks.

In the "DHCP server" setting of the wireless router, the DHCP server is set to "not enabled".

Four, enable MAC address, IP address filtering

In the wireless router's settings, enable the MAC address filtering, should pay attention to is, in the filtering rules must select "allow only set MAC address MAC address in the list in the entry into force of the wireless access network" this kind of options.
