How to hide computer in wireless network
There are many ways to hide your computer in the wireless network, for example, click "Start / Run", then enter "cmd" to open a command prompt window, enter "net config server / hidden: yes" in the window, or In the properties window of the wireless network connection, cancel "Microsoft Network File and Printer Sharing", so that others cannot find their computers through My Network Places.
In order to prevent the computer's IP address from leaking, you can enable the firewall function of the wireless network connection and set ICMP in the "Advanced" tab of the firewall properties to prohibit all incoming and outgoing requests so that others cannot use ping.exe Determine whether your computer is online.
WinXP automatically manages the wireless network by default. In fact, it is only necessary to allow the system to automatically connect to the wireless network when it is necessary to access the wireless network resources, so you can cancel the "Configure my wireless network settings with Windows" option at ordinary times. This is not only safe, but also Save more resources. Or click the "Advanced" button to cancel "Automatically connect to a non-preferred network" so that the system will not easily connect to a wireless network that has not been previously detected.
Wireless router is invisible but accessible
The most direct way to hide the wireless router in the air is to stop it from broadcasting the SSID. The SSID broadcast function allows the wireless network created by the wireless router to be searched by the client. This is convenient for users to access the wireless network, but it is also convenient. Illegal access, so in situations where security is required, such as a company network, it is best to ban it.
As a result, the wireless network created by the wireless router cannot be found as usual with WinXP or the wireless network card's own program. To access it, you can only manually add the preferred network and specify the SSID name.
Hidden SSID broadcast can not deal with NetStumber, it can still detect the hidden wireless network, so you must reuse some functions of the wireless router itself, including stopping the DHCP service and modifying the default IP address of the LAN port. Because the SSID of the wireless network uses broadcast Even if the wireless network is detected, if the intruder does not obtain or configure the IP address of the same network segment as the wireless router, it still cannot connect to the wireless router. This is also a prerequisite for TCP / IP network communication, that is The IP addresses of devices in the same network must be on the same network segment.
The content of the wireless network and wireless router we introduced in the previous article is a lot, this article only introduces a trick, I hope everyone has mastered it.
