For ordinary users, it is not necessary to understand the concept of SSID and security key to achieve a secure connection, and the user's security key can not be cracked by outsiders, because it is randomly generated, and most importantly, users do not have to memorize lengthy wireless encryption password, avoid the trouble of forgetting passwords.

As a result, simple packet-filtering firewalls are sufficient for small offices, such as those that are randomly brought by many DSL or cable routers. These include broadband routers from companies such as D-link, 3Com, Netgear and Linksys. In addition, WatchGuard Firebox Soho, Symantec Firewall 100, global technology company Gnat, NetScreen and Sonic

The M bandwidth enables the user not only to transmit the ordinary data packet, also may transmit the video and the audio and so on multimedia file, provides the foundation for the wi

Suppose an identification process takes 1.5 seconds. With a maximum of 11,000 identification, the hacker may gain access for approximately 4.5 hours or less (perhaps nearly 2 hours). In the coffee shop or on many other occasions, two hours will certainly not attract the attention of others. As its name implies

The complete security features include IEEE802.1x port-based authentication and access control list, ensuring that only authenticated users can access your network. You can use SecureSocketsLayer (SSLv3) and SecuredShell (SSH) suitable for command line configuration on the GUI for WEBGUI security management ). Additionally, multi-layer switches can be manage

Create an experiment environmentBefore we begin, our first step was to build an experimental environment where you could not use others' networks to crack your work. This would violate the law and be an immoral act. To build a wireless network platform in an experimental environment, Wireless AP is indispensable. In addition, three laptops with wirel

This includes about 30 Linksys devices, 10 Netgear devices, and many other devices.

The price is an issue that needs to be considered when purchasing any product. For ordinary domestic users, the price of a wireless router may not be higher or better. You should choose the price based on your actual situation. Recommended Purchase: compared with the same period last year, the price of wireless routers has dropped a lot. Currently, the price of ordinary household wireless routers is acceptable. When purchasing a home wireless router, we recommend that you selec
We have introduced three encryption methods: WEP encryption for conventional wireless security measures, restriction of MAC addresses for wireless NICs to make the network more secure, and prohibition of wireless SSID broadcast to protect network security, the WPA-PSK wireless encryption introduced in this article is a special encryption method, because some NICs do not support this encryption method.

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.
