Describes the main functions of a wireless router.

With the development of China's routing industry and the upgrade of the wireless router technology, I have studied the features of the wireless router and will share with you here, I hope it will be useful to you. DHCP can automatically assign IP addresses to each computer in the wireless LAN. You do not need to set IP addresses, subnet masks, and other required TCP/IP parameters. If DHCP is enabled, you can easily use your wireless network. Therefore, it is necessary to disable DHCP for wireless networks.

Set the DHCP server to "disabled" under the "DHCP server" setting of the wireless router. Test results: Because the IP address and DNB server information cannot be obtained, the network is still unavailable even if the wireless network signal can be found.

Enable MAC address and IP address filtering

When you enable the MAC address filtering function in the settings of a wireless router, note that, in the filter rule, you must select the option "only allow valid MAC addresses in the configured MAC address list to access the wireless network.

In addition, if DHCP is disabled in the wireless LAN, we recommend that you set a fixed IP address for each computer that uses the wireless service, then, enter the IP addresses in the IP address permitted list. After the IP address filtering function of the wireless router is enabled, only users of the IP address in the list can access the network normally, and others can only be stunned.

Test Results: After the MAC address filtering and IP address filtering settings are completed, even if some people barely intrude into the wireless network, the MAC address and IP address are disabled by the filtering function of the wireless router, therefore, the wireless network is still unavailable.

Summary

In fact, during the actual test, we found that any method mentioned above can protect your wireless network. Therefore, ordinary users do not have to worry about it and can use it with confidence.

In addition, if you use public wireless networks at airports, conference rooms, and other public places, remember to disable your own documents and print sharing functions, this type of shared documents can be easily accessed by another client in the same LAN.
