In August 13, millet new product launch, Millet again launched a "Millet Router Youth Edition" version, the price is only 79 yuan, is a very affordable smart router. However, a lot of careful friends will find that the millet router in the appearance of the youth version of the previous introduction of the Millet router

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

Lei Branch Router is more well-known routers, Word-of-mouth is also quite good, in fact, the LEI branch router set method and other general home router Setup method almost. However, there are still some novice friends will not get, want to small write a section on Lei ke Netcore wireless router setup steps and tutorial
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 introduces Tengda (Tenda) FH903 wireless router connection, Internet settings, a new purchase (after the factory set up) Tengda FH903 wireless router, to achieve Internet connection, need to go through the following 4 steps: 1, set up computer IP address; 2, Connection Tengda FH903 router, 3, Tengda FH903 router
At present, China's wireless routers are developing rapidly, and there are also many problems. The following describes the problems that wireless routers often encounter during the connection process and gives you a detailed analysis. With the popularity of wireless networks, wireless routers gradually enter our lives. However, if you purchase a wireless router, in addition, you must also use the original wired wireless
The communications department allows each broadband user to use two computers to share the Internet, and the user needs to install a broadband router. So, what kind of router should be purchased more appropriate?
Today's broadband router many features for the average home user is really very practical, can improve the performance of many Web applications. The fo
A, the classification of routers
According to the performance grade: the back plate exchange capacity of more than 40Gbps routers called high-end routers, less than 25Gbps called low-grade routers.
By structure: Routers can be divided into modular structure and non modular structure.
The modular scene structure can flexibly configure the router to meet the increasing business requirements of the enterprise, and the modularization can only provide a
are multiple network interconnection methods, among which the most commonly used are bridge interconnection and router interconnection.1.1 network connected by bridges The second layer in the OSI model, that is, the link layer. 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
Why bridge the wireless router? The benefits of wireless bridging, bridging can be two different physical locations, inconvenient wiring of users to connect to the same LAN. Wireless bridging can also play a role in signal amplification. We can bridge multiple wireless routers together to achieve the signal coverage. At least one router supports the WDS feature, but the two routers don't have to be the same
In the days when wired network is ubiquitous, the "figure" of WLAN is moving closer and nearer to us, which is very much in step with the wired network. Considering the current wireless LAN is through the wireless router to network, wireless LAN can be efficient Internet and wireless router status closely related; Unfortunately, wireless routers in the long hours, often appear a variety of "strike" phenomen
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
How do I set up a wireless router? will be discussed in this section, the main of this series of courses the purpose is to popularize the basic knowledge of wireless router, introduce the basic function of no line, show more uses of wireless router. There is no inscrutable technology, no jerky nouns, no messy settings, just telling you How to set up a wireless
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
