For everyone in the process of using the router encountered problems, small series I think it is necessary to popularize some of the router's small knowledge, I believe that as long as you carefully read, you will suddenly see the internet is no longer difficult!! One, WAN Port no connection Two, the WAN Port has the connection, but the connection failed. Third, broadband normal, you can ping, but unable to open the Web page Wireless c

router routing and network delay caused by the increase in packet forwarding efficiency.Routers: Traditionally, routers work on the third layer of the OSI layer Seven Protocol, whose main task is to receive packets from a network interface, and decide to forward to the next destination address based on the destination address contained therein. Therefore, the router first has to find its destination addres

The deployment of wireless networks in an enterprise environment facilitates the mobile office within the enterprise. The wireless router is the core component of the wireless network, and its running state determines the transmission capability of the wireless network. Because of this, it is the administrator's first concern to maintain the wireless router so that it runs safely and efficiently. Below a

Now basically everyone a smartphone, and many users also have laptops, tablets and other digital products, many family members of the wireless network requirements are generally high, and the traditional telephone line network due to low broadband, it has been difficult to meet the family members of many internet users need, So today many friends pull broadband will choose the network performance better fiber optic network. However, the computer Pepsi Network found that many friends do not know

This article describes the basic working principles of routers in TCP/IP networks, introduces several functions of IP routers, and provides Static Routing and dynamic routing protocols, as well as the concept of the internal gateway protocol and the external gateway protocol, and briefly introduces the most common RIP, OSPF, BGP and BGP-4 routing protocols, then, it describes the design objectives and types of routing algorithms, and focuses on the link state method and distance vector method. A

This article uses a specific example to illustrate how to configure the access to ADSL through the vro. What problems should we pay attention to during access? The following articles will benefit you a lot. Note: In this case, a common adsl modem and a cisco 25001841) router (dual Ethernet port) and IOS 12.2 (15) T need to be used to connect to the China Telecom adsl PPPoE, able to achieve LAN Internet sharing. The configuration of this case is divide

. Every 30 seconds, the distance vector routing protocol sends the entire route selection table to the adjacent site to update the route selection table of the adjacent site. In this way, it can be directly connected from other sites or other methods) to collect a list of networks for route selection. Distance Vector Routing uses the number of hops as the metric value to calculate the number of routers that need to pass to the destination.For example, r I p uses the B e l m a n-F o r d algorithm

In-depth analysis on the disconnection of A Broadband Router, there are many things involved in the disconnection of a broadband router. There are also a variety of solutions, so there will be a bit of confusion in the selection of methods, the following shows you a way. Q: in-depth analysis on the disconnection Problem of A Broadband Router. A: I often see many

The slow speed of wireless networks and unstable signals are widely recognized as drawbacks. In fact, the actual situation may not be a problem with the network itself. Have you checked whether the parameter settings of your hardware device are correct? Follow this article to see the correct process of configuring a wireless router. I believe that after reading this article, you must be able to configure a wireless

Perhaps because many administrators are unfamiliar with the router or understand the reasons for not in-depth, a large number of router hardware failures appear on the software, the following we mainly analyze several common router hardware failures. Router hardware failure is the problem we often encounter, here we

Shortly before the introduction of a new Fibonacci news HGE1208 Wireless router, set up compared to the previous generation of products more concise, easier to start. Sanlian Small Series today will bring the detailed Fibonacci HGE1208 wireless Router Setup tutorial, together to see the new Fibonacci Router installation and setup steps bar. First, th

Not long ago for everyone to bring a "router how to set up security," the theoretical article, a lot of friends read may feel more abstract, today small set for everyone to bring a combat article, to the Fibonacci wireless router for example, to teach you how to set the security of the Fibonacci router. Through the router
