Several Methods for configuring wireless routers are network security upgrades.

Are you always worried about your network security? Is it always a headache for tedious encryption? This article will introduce several wireless router setup steps to help you improve your network security level. I believe that this article will help you solve the problem of wireless network security.

Wireless router settings 1 disable DHCP

DHCP is the abbreviation of Dynamic Host Configuration Protocol (Dynamic Host Allocation Protocol). Its main function is to help users randomly allocate IP addresses, this saves the trouble of manually setting IP addresses, subnet masks, and other required TCP/IP parameters. This is a user-friendly feature, but it is used by many people with ulterior motives. Generally, the DHCP function is enabled by default, so that all wireless devices in the signal range can be automatically allocated to the IP address, which leaves a great security risk. Attackers can easily obtain a lot of information about your vro through the assigned IP address, so it is necessary to disable the DHCP function.

Wireless Router setting 2 wireless encryption

Nowadays, many wireless routers have the wireless encryption function, which is an important protection measure for wireless routers. Data Encryption in radio waves ensures the security of transmitted data information. Generally, wireless routers and APs have the WEP encryption and WPA encryption functions. WEP generally includes 64-bit and 128-bit encryption types, you only need to enter 10 or 26 hexadecimal strings as the encryption password to protect the wireless network. The WEP protocol encrypts data transmitted wirelessly between two devices to prevent illegal user eavesdropping or intrusion into the wireless network. However, the WEP Key is generally stored in Flash, therefore, some hackers can use vulnerabilities in your network to easily access your network.

WEP encryption appeared earlier and has now been upgraded to WPA encryption. WPA is a standard-based and interoperable WLAN Security Enhancement solution, the data protection and access control level of existing wireless LAN systems can be greatly enhanced; WPA enhances the algorithm for generating encryption keys, even if hackers collect and parse group information, it is almost impossible to calculate a general key. The emergence of WPA makes network transmission more secure and reliable.

It should be noted that the wireless encryption function is usually disabled when a wireless router leaves the factory, but if you give up this function, your network is an extremely insecure network, therefore, we recommend that you enable this function after setting it.

Wireless router settings 3 Disable SSID Broadcast

In short, the SSID is the name you give your wireless network. When searching for a wireless network, your network name is displayed in the search results. Once attackers use a common initialization string to connect to the wireless network, it is very easy to intrude into your wireless network. Therefore, I strongly recommend that you Disable SSID broadcast.

Note that the access point of a specific model or the default SSID of the router can be easily searched on the Internet, such as "netgear, linksys, etc.", so you must replace it as soon as possible. For general families, select a name that is quite different.

If you disable the SSID and then search for the wireless network, you will find that the wireless network is ignored by the wireless network adapter because no SSID broadcast is performed, especially when you use Windows XP to manage the wireless network, the goal is to keep wireless networks invisible. However, disabling the SSID will slightly reduce the network efficiency, but greatly improve the security. Therefore, disabling the SSID broadcast is very worthwhile.

Wireless router settings 4 set IP filtering and MAC address list

Because the MAC address of each Nic is unique, you can set the MAC address list to improve security. After the IP address filtering function is enabled, only users of the IP address in the MAC list can access the wireless network normally. Other users that are not in the list cannot connect to the network. In addition, You must select the "allow only valid MAC addresses in the configured MAC address list to access the wireless network" option in the "filter rule, otherwise, the wireless router will prevent all users from connecting to the network. This method is very practical for home users. Just add several computers in the home to the list, which can avoid the "network" of neighbors and the intrusion of attackers.

Wireless router settings 5 active updates

Search for and install the latest firmware or driver updates for the used wireless router or wireless network card to eliminate previous vulnerabilities. In addition, you can download and install the wireless function updates of the operating system, such as Windows XP SP3 or Vista SP1, to better support the use and security of wireless networks, enable your device to have the latest functions.

If you forget your password, you can restore the device to the factory status, that is, press and hold the reset key, but remember to reset it.

Wireless Networks are getting faster and faster, and wireless networks should be more and more secure. In fact, you only need to perform the preceding simple settings to increase your security level a lot. The wireless network environment is not as simple as connecting, so that security work can be done at home to make use more comfortable. The methods described above are simple but practical. If your wireless router has not applied the above methods, I strongly recommend that you perform these settings now.
