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. Today is suddenly unavailable, wireless and local are dead, the display cannot connect to the Internet. Reset key pressed over, reboot, and even restore factory reset. Not yet. Angry half to death. What the hell is going on here? (Also, the wireless
1. 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

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.

Complete data frame) forwarding, the main purpose is to provide transparent communication between Connected Networks. Bridge Forwarding is based on the source address and destination address in the data frame to determine whet
One, the internal components of the Cisco routerIn order to configure, Cisco Internetwork and troubleshoot, we must first understand the major components of the Cisco routers and understand these componentsThe respective function.Table 7-1 gives a description of the major components of the Cisco router.
The micro-code that the bootstrapper stores in ROM, the main function is to start it when the router

This article takes the di-740p model of broadband router D-link, the default management address is 192.168.0.1, and the management port is 8080.Set the IP address and router management address of a computer to the same network segment, such as 192.168.0.2, open the browser of 192.168.0.2 computer, enter "http://192.168.0.1:8080"
Generally speaking, the router is establishes the LAN and the WAN Connection bridge, but at present the backup router's application is very widespread, simultaneously its function also more prominent. Cisco routers have a variety of backup technologies, today I will introduce the router's own backup technology and line backup technology.
First, the router backup technology
The router's own backup technolo
update from an adjacent site within 9 0 seconds, it does not consider the neighboring site unreachable. Every 30 seconds, the distance vector routing protocol will send the entire routing table to the neighboring site, so that the routing table of the neighboring site is updated. In this way, it can collect a list of networks from other sites (directly connected or otherwise) to make routing choices. The distance vector routing protocol uses the hop count as a measure to calculate the number of
The OSPF protocol is very important for the use of Cisco routers. But how do I perform specific operations? The following article will give a detailed explanation.
OSPF protocol operation:
1. the ROUTER that declares OSPF sends a HELLO message from all interfaces that start the OSPF protocol. The two routers share a Public Data Link and can negotiate with each other the parameters specified in their HELLO packets. Then they become neighbors Neighbor)2

Early domestic ADSL line access are bridge mode, by ADSL modem and computer, in the computer to allocate fixed IP address, boot can access to the local terminal equipment into the Internet. However, when the user does not boot on the Internet, IP is not to be exploited, will cause the current increasingly scarce public network IP resources waste, so there has been a PPPoE dial-up ADSL access.
PPPoE dial-up can enable the user on the power-on dial-up access to the local equipment, by the local e
In the network, the use of various hardware will cause a high temperature environment. So we can use the hot backup routing protocol HSRP) for configuration. So what is the hot backup routing protocol HSRP )? The Hot backup routing Protocol HSRP, Hot Standby Router Protocol) is a routing Protocol that allows hosts on the Internet to use multiple routers as a single virtual Router) to maintain the connection
What if the router interface doesn't open? Don't worry, here are your illustrations.

While cyber security experts are focused on developing devices that block Dos attacks, they have little effect because Dos attacks exploit the weaknesses of the TCP protocol itself. Properly configured routers can effectively prevent Dos attacks. In Cisco routers, for example, the iOS software in Cisco routers has many features that prevent Dos attacks, securing the rout
The wireless router is the transmission media, this article from the author's own TP-LINKWR641G as an example, describes the specific operation steps of the wireless router configuration, and describes the WAN port settings and other issues.
As we all know in the tutorial on setting wireless routers, wireless signals are the carrier of data transmission, which means that the stability of wireless networks i
There is no fixed standard for understanding the Wireless Router Protocol. Generally, the standard is IEEE 802.11g. Other content of the wireless router is described in detail later. In our contact, these standards have little impact on us.

Currently, wireless routers support the IEEE 802.11g Wireless
When we use the Router device for networking, once encountered similar router device panic, the network is frequently dropped phenomenon, we can consider the router upgrade in order to timely fix the router system itself bugs, to ensure that the efficiency of the router more

With the development of China's routing industry, it has also promoted the continuous improvement of router protocols. Here we mainly introduce the knowledge of router protocols that network engineers should have mastered. Distance Vector router protocols are designed for small network environments.
