Solve the problem of enterprise wireless network stability and security (II.)

Key elements of enterprise wireless network stability

Although the Enterprise wireless network eliminates the wiring trouble and the line problem brings the network not to pass the problem, but because of various external factors interference wireless local Area network stability question also became the enterprise attention goal. Enterprise wireless local network in the operation of the biggest problem is to drop the line problem, the following for you to summarize the experience of business Management Lao Zhang:

At present, the biggest cause of the enterprise wireless network drop is: Air-conditioning, Bluetooth, electronic remote control and other devices caused by interference, its electronic frequency and wireless network WiFi frequency is very easy to conflict. So first pay attention to the surrounding environment of the Enterprise wireless network. As far as possible the wireless equipment placed in the open area, which is conducive to reducing signal transmission barriers to improve network reception sensitivity. For wireless channel selection, be careful not to conflict with each other. (Here, in order to avoid trouble, it can be set to a less common wireless channel.) ）

For the network drop instability problem that excludes the above reasons, you need to look up the device's driver problem. If the enterprise overall wireless network operation is good, but the individual machine appears the network instability phenomenon to enter, then the problem must appear on the single machine. First, using the replacement method to detect the performance of wireless network card, in the normal case, only need to check the wireless network card driver (can be directly reload drive).

Finally, we should pay attention to the IP static and dynamic allocation of the device, which is randomly allocated, while the static security is higher. It is usually set up as follows: Enter the Web Administration page of the wireless router and set the address pool parameter in the DHCP service Settings area to a section of IP address other than the static address, thus excluding the wireless network conflict between static and dynamic IP.

Safety attention problem of Enterprise Wireless LAN

As a qualified manager, although the security strategy is in place, but also pay attention to the security issues after the inspection, in order to immediately detect security problems. Here is a summary of a few:

Always check the AP username and password as well as the MAC address, and check the encryption method to prevent people from being maliciously modified.

Detect the firewall settings of each host and the performance of antivirus software. To prevent the machine from poisoning and dismounted, which leads to the data through the wireless LAN leak problem occurred.

And for the management of enterprises, the higher departments for enterprises connected to the network of computer users should establish a set of security mechanisms, the requirements of wireless network considerations, to ensure that all employees must be aware of the provisions, and strict implementation. Only in this way can the enterprise's wireless network be carried out in the end through the mutual interaction between the management and the employees.
