Four ways to ensure wireless network security

One of the methods: qualifying IP addresses

When your computer is connected to your network, your wireless router usually gives him an IP address to browse the Web or connect to the external Internet. Typically, a wireless router assigns an IP to each machine that is connected to a wireless network. But you can tell your wireless router to assign only a certain range of IP addresses, and your wireless router will not assign IP addresses to intruders if the computers in your network use all the IP addresses. For example, your home has two wireless internet access computers, you specify your wireless routing, only 192.168 1.1 to 192.168.1.2, so that when your two computers are on the Internet, others can no longer allocate IP, and if you find that your computer does not allocate IP, I knew your downstairs guard had killed the thief.

Method Two: Hide the wireless ID

When you buy a wireless router to set up a wireless network at home, your home has a Wi-Fi wireless network environment. When you open your notebook or other mobile device and look for a wireless network, you can see a lot of network names, which are the service settings identifier (SSID). The default SSID is typically associated with the router's brand. For example, if you buy Tp-link, your SSID must begin with Tp-link. A hacker can easily know your router brand through your SSID. You can change the SSID to a name you like in a line-free management interface, at least to some extent to conceal your wireless route. Modifying the SSID is the easiest way to do it, and we can do better by turning off the SSID broadcast. Take the Linksys management interface for example, in the Setup option, the SSID broadcast can select Disable, which turns off the SSID. So your wireless network, for the average person, is hidden.

Method Three: MAC address filtering

How do I check the ID of the MAC address of my computer's network card? Select Start menu in Windows System, then run, enter "CMD" in the pop-up dialog box, and the Command line window appears after the carriage return. Enter Ipconfig/all in the Command line window. Look for this line named "Physical Address", which is the MAC address of the device. Each network device has a unique ID called a MAC address, typically in this format: 00-d8-a1-40-9f-62. You can use him to come outside the door of the intruder. Many routers allow you to set a range of MAC addresses that can be plugged into the Internet. This way you can tell the wireless router which is the MAC address of your own PC, and not be excluded from this range.

Method Four: Encrypted wireless network

Generally no lines are provided with two encryption standards: Wireless Peer-to-peer Protocol (WEP) and Wi-Fi Protected Access (WPA). WEP is older than WPA, but not as safe as WPA. At present, online popular, "10 minutes to crack the wireless router password", means to crack the WEP password. So it would be safer to use WPA, at least to create more trouble for hackers. After you set up encryption, you need to view wireless network properties on a computer that requires wireless Internet access, and you can enter a password in the Network Key dialog box to connect your PC to your wireless network using WPA encryption.
