device manufacturers have set the factory configuration of their products to disable WEP mode. The biggest drawback is that data can be directly read from the wireless network, as a result, hackers can immediately scan all kinds of information on your wireless network from the beginning. Change the Service Set Identifier and Disable SSID Broadcast Service Set Identifier SSID) is the identity identifier of the wireless access network technology, which is used by the user to establish a connecti

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 select the wireless suite provided by the corresponding manufacturer, so that you can get more benefits. Household wireless router purchase keywords: Brand Most of the time, brands influence consumers' purchasing orientation. W

common HUB, that is, a HUB, lags behind a switched HUB (vswitch) in its working mode. Therefore, when funds are sufficient, the speed of using a switch is much faster. But it is better to use some of the miscellaneous vswitches, rather than buy a 3COM or D-LINK with more money. If the funds are insufficient, it is best to make good use of the HUB. 3. network cable Don't underestimate the network cable. The network cable of miscellaneous brands and so

world, such as Nokia, 3COM, CISCO, Siemens, Alcatel, Paradyne, have successively launched ADSL products and are committed to the development of ADSL; many telecom companies and ISPs around the world have also promoted their respective ADSL Services. North America and Singapore are the first to officially open their business. Japan, South Korea, and other countries have entered the trial phase, china Telecom has carried out relevant network tests in B

optimizing transmission and realizing data traffic distribution. The current situation of networks under multi-line applications is the most prominent manifestation of the interconnection between different line operators. Under normal circumstances, the communication between operators of different lines needs to be transferred through a specific gateway, with a latency of more than 420 milliseconds. However, VPN devices integrated with multi-line smart technology are switched, the latency can b

Wireless Access Node. The client uses the SSID to initialize the connection. This checker is set by the manufacturer. The same default value is used for the same manufacturer's products. For example, 3Com devices use the "101" string. If the hacker understands the corresponding initialization string, the unauthorized link can be easily established. Therefore, I suggest you change the SSID initialization string When configuring your wireless network s

know what tag should be added to the sent packet so that the vlan of the packet is the voice vlan configured for the interface connected to it? This is achieved through the LLDP protocol. The ip Phone Number communicates with the switch through LLDP. The switch sends the voice vlan of the interface to the ip phone number through LLDP protocol. 2. The voice device that does not support tags, for example, Huawei's EchoLife ET65 ip phone sends/receives packets without tags. In this case, the OUI f

focus of competition for Internet cafes, the speed is faster and more important. The performance of the optical fiber access network is constantly improved, and the price of copper cables is continuously increasing. This is a potential advantage of the optical fiber access method. Although the cost of optical fiber access is still a sensitive topic, the access cost has been continuously reduced as the optical fiber access network becomes more and more widely used, in addition, optical fiber acc

different. IP phones can be used independently without connecting to individual phones .) Hardware phone number) A hardware phone is an independent network phone device that does not need an external computer. It looks like a traditional phone, but uses the Ethernet to connect to the router. It can communicate directly with the VoIP server or gate device without using a personal computer. Therefore, the user does not need to install any software during use. Hardware phones are much more expens

Bluetooth interface. Access Point settings for wireless routing clients In this section, we will explain the configuration of Wireless Access point. Other options will appear on the Access point configuration screen to help you configure the device. The initial configuration of Access Point varies with the vendor. The Access point of 3Com uses a crossover cable and a terminal. Proxim HomeRF wireless gateway uses the preferred wireless client for conf

vulnerabilities, it is quite effective to prevent common hackers. Many vendors of Wireless Access Node products set WEP to disable for easy installation. Therefore, once the node antenna starts to send and receive signals, hackers can use the sniffer to access wireless data in plaintext. Wireless Network Application configuration 3. Change the SSID settings and cancel broadcasting The service set identifier (SSID) is used to identify the initialization string used by the Wireless Access Node. T

The more users, especially administrators, learn about malicious hacker activities, the easier they will find coping strategies. Network administrators should collect logs about scanning and access attempts, and use a large number of existing statistical generation tools to make these logs more useful. You also need to se

above tests, we recommend that you consider the test items listed below during the test. 1) Functional testing: It mainly verifies whether the product has every function designed. 2) stability and reliability test: Generally, the method of increasing the load is adopted to evaluate and analyze the running capability of the equipment under long and high load conditions. 3) interoperability test: different network products must be able to communicate with each other. Test the interoperability rou

cables and network adapters, to form a wireless Route Test Scheme for data transmission modes in different network segments in a campus network. In addition, we have also selected a site in Beijing that can be used for long-term unlimited download and a FTP site in Wuhan for remote transmission and wireless routing testing. Actual wireless route test: After debugging the three networks, we tested the wireless route for data transmission during the peak hours of the network. 1) in the same CIDR

In fact, the configuration methods for different vrouters are very similar. Next we will explain some common vro setting methods. With the rapid development of network technology, Internet is widely used, the requirements for communication media are getting higher and higher. Frame-relay) is rapidly popularized because of its stable communication, fast speed, and favorable price. The key to making good use of Frame relay is CISCO router settings. The following describes the frame relay configura

the identifier of a 3Com device. If hackers know this phrase, they can easily use your wireless service without authorization. For each Wireless Access Point deployed, You must select the unique and difficult to guess the SSID. If possible, do not broadcast the identifier outward through an antenna. In this way, the network is still available, but it does not appear on the list of available networks. Disable DHCP This makes sense for wireless network
