How To Protect Your Network

As the title, there may be many friends have this problem. Well, follows are 7 ways that tell you how to protect your wireless network.
1. Modify the SSID information, and prohibit the broadcast .
Turn off SSID broadcast, can be greatly reduced chance of found, specific closed method see the router configuration interface.
2. Using WPA2-PSK encrypted wireless network
Use AES of WPA2-PSK to encrypt, passwording setting as long as possible. Use uppercase and lowercase letters plus numbers plus symbol combinations, increase the difficulty of other’s crack. And set the group key update cycle in 12 to 24 hours (too short can cause the wireless connection exception), this can increase the difficulty of deciphering the password. Note that WEP WPA encryption algorithms have been solved now, if the older network card does not support WPA2 , should try to use WPA encryption and password with uppercase and lowercase letters plus numbers plus the combination of symbols can also play the purpose of encryption.
3. Reduce the signal transmission power
Reduce the signal transmission power, wireless devices(such as wireless gateway router) can be reduced the discovery chance, through the antenna surrounded by cans, etc., this can transmit signals to directional emission, reducing the other direction signal, also can use the router comes with power regulation for Regulation (DD-WRT, TOMATO firmware also have this feature).

4. Open the MAC address filtering
Add all of your own computers to the white list MAC, and prohibit other customers to access. Also, note that the filter can not prevent 100% of net rub, MAC sent in plain text, data transmission may result in MAC intercepted, others can modify the MAC, also access.
5. Setting Channel
General routers default to channel 6, if multiple routers are made in a limited space channel 6, the signal will be very poor, users may be unable to connect to the router, so set the channel away from 6, but there are also some use 1,13,14 Channel, so these channels should be avoided, use the middle of the channel, such as :3-4,8-11. Reduce the chance of being found.
6. turn off DHCP function
Turn off DHCP function reduces the chance of being found.
7. Upgrade router firmware at regular intervals
Due to the different router brands, you can use your router manufacturer's official website to see if there is a firmware upgrade, the upgrade can fix some router security issues.
