Ii. Common wireless network security measures
Based on the above security threats to wireless networks, it is not difficult to find that "Access Control" is the most direct measure to ensure the security of wireless networks. At present, the wireless network security measures are basically used to defend intruders at the access level. Commo
are only 1-3 dB. (In the future, we can take some time to talk about the antenna gain, at present, it is easy to understand that the larger the number of dB, the stronger the antenna's sending and receiving capabilities) the wireless router is 2-5 dB. To transmit signals to some closed corners, many people usually choose to replace larger-gain antennas on wireless NICs or routers, or choose enterprise-level wireless routers with higher output power, in this way, the intensity of the radio wave
for WPA authentication:
1: PMK (PSK)
2: PTK (PMK, "pairwise key expansion", AA, SA, anonce, snonce)
Brief description of the four handshakes:
1: The Wireless Access Point AP sends a random number anonce to the client Sta.
2: STA receives anonceThen, select a random number snonce, calculate the PMK (PSK) using the WPA password (passphrase) and the ap ssid, and useThe PRF-X function is used to calculate the PTK, and the first 16 bytes of the PTK a

H3C has always been committed to high-end network products, and its self-developed WA1208E is widely applied in wireless city networks. Its stability, practicability and security have been well received by everyone. Today, we will take WPA/WPA2 encryption as an example to explain how to set the WA1208E wireless encryption mode.1. First, create the SSID name [H3C] ssid wa1208New
are using a 11g product, the three encryption methods are compatible. However, we do not recommend that you choose WEP, an old and easier-to-crack encryption method.
Step 2: Modify the default user name and password
After setting wireless encryption, we need to modify the Default Login username and password of the wireless router. Why? The reason is very simple, because the default user name and password set by the wireless router of the same model or even the same manufacturer are almost the s
functionality required for configuration is the same.
The first step is to modify the SSID
After landing router configuration interface, click on "Wireless Installation"? "Manual Wireless Internet Installation"
The following figure shows that the SSID in the default state of the router is DLink, while the SSID is broadcast state.

On the Internet to see how to prevent the problem of hijacked routers is very good, it is true that we use the router at the same time should be prevented from being hijacked to protect our privacy and property security. Today, I share my personal experience of preventing routers from being hijacked.
A, hidden wireless signal name (SSID number) so that people do not search. After being hidden,
Telephone adapter and Broadband RouterNot long ago, Linksys launched two new Internet phone products. One is a analog phone adapter, which has two phone jacks that provide VoIP services, and can be used by any common home phone. Most users want to share Internet connections with their computers at the same time. If a user already has a vro, the analog telephone adapter can connect their phone to VoIP to provide services; otherwise, they will need a Br
aerial backup.
If you hate this slow Wi-Fi speed, but don't want to go back to Ethernet, we offer you some tricks to improve speed.
1. Check your router's ecological settings
Some routers are set to "save Power" mode by default, with the goal of saving a few watts of electricity. However, this commendable approach will reduce bandwidth accordingly. Although I trust the Linksys WRT610N router is not set up for this unnecessary power-saving mode, I
been found.② just found the device status is a question mark, option an AP, click "Permit", allow the use;When ③ is granted, their status is green; The connection can be seen by the AP from the firewall to the DHCP assigned to the address, by accessing this address, you can also log in to the Web interface of the AP. Establish SSIDAfter activating the FORTIAP on the firewall, you can set the SSID, use the wireless to know that the notebook or mobile
.
Network = {
Ssid = "simple"
Psk = "very secret passphrase"
# The higher the priority, the earlier the match can be made.
Priority = 5
}
# It is the same as the previous setting, but requires scanning of the specific SSID (for those APS that refuse to broadcast the SSID)

difficult to diagnose.
To avoid this situation, after each wireless access point is inserted into the installation location, ensure that it is powered on, the status indicator is operating properly, and each wireless access point is installed to obtain network and Internet connections. Check the signal level of the wireless access point to ensure that it is connected to the correct wireless access point.
2. Check the VLAN of each SSID
