Because of the continuous advancement of social informatization, people's demand for data communication is increasing. Since the launch of TCP/IP protocol cluster in the 70 's, it has developed into the fact standard of Network layer communication protocol, and the Internet based on TCP/IP has become the largest and most important network. As the core equipment of IP network, routers have been widely used. As the core equipment of IP network, the technology of

Many junior network administrators ignore security settings when using Cisco routers, and the following three are ideal for novice users to configure network security when using Cisco routers. One, the security configuration of the router "access control" 1, the administrator who can access the router is strictly controlled. Any maintenance needs to be documented. 2, the

The network bridge can connect two different physical local area networks, it is a kind of storage and forwarding device that realizes LAN interconnection in the link layer. The Network Bridge receives the MAC frame from a local area network, after unpacking, proofreading, verifies, presses another LAN's format to reassemble, sends to its physical layer. With the development of wireless network, more and more companies and enterprises have already started to layout wireless LAN, today we mainly

With the growing sophistication of wireless technology and the continuous enrichment of wireless products, the need for people to use wireless networks is increasing. Because of its simple network and convenient use, the wireless router has become the main mode of the network, so it has been paid more and more attention to the methods and techniques of the fault handling of wireless networks. This article will introduce the common but very easy to ign

Router tplink845 Wireless bridge unsuccessful solution: For older products, in the Admin interface click Run Status > Wireless status, WDS status continues to display scanning, initialization, correlation, etc., as shown below: The above phenomenon indicates that the WDS bridge did not succeed. Use the following methods to troubleshoot problems. 1, confirm the bridge is the correct signal When you set up a wireless bridge,

tplink885n setup steps as follows A new purchase (Restore factory settings) of the tl-wr885n router, to achieve the Internet function, need to carry out the following 3 steps: 1, tl-wr885n router installation, 2, set the computer IP address, 3, tl-wr885n router Internet settings. Step one, tl-wr885n router installati

Broadband routers are the necessary devices for sharing the Internet, and multiple computers are connected to receive distributed signals from the broadband router. Therefore, this aspect of maintenance and troubleshooting work can not be ignored. Therefore, this paper selects the most common fault phenomenon in the daily use of the broadband router, and puts forward the solution. Hope that through this art

When information needs to be transferred between two networks, the interconnection device of common routers is responsible for the transmission of data. The main work of the router is: The decision of the path and the forwarding of the packet (from the router an interface input, and then select the appropriate interface output); Maintenance path by the table.The way the

Tp-link routers cannot connect to the Internet a workaround Tp-link wireless router, model "tl-wr841n", can be used yesterday, whether it is wireless or local connection.

No line by automatic dialing failure When using a wireless router for broadband dial-up access, we may often encounter the device can not automatically dial the strange phenomenon, when we encounter this phenomenon, we can from the following aspects to check: first of all to confirm the use of their own wireless router is the local telecommunications Department of the network license, If the device does

Original article: Grassroots Maintenance-Router network 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 th

If a Cisco Wireless Router is improperly configured, problems such as disconnection and disconnection may occur. It is very important for us to have a deep understanding of the details in Cisco wireless router configuration. Next we will introduce the relevant knowledge in detail. As we all know, wireless signals are the carriers of data transmission, which means that the stability of wireless networks has

A home broadband router is a broadband router with a smaller number of users, such as a 4LAN-port router, which allows 4 computers to surf the internet at the same time. If a home/dormitory/small office has multiple computers that need to be connected to the Internet at the same time, using a router to form a small loc
