Overview: analyzes and solves some problems when accessing the internet at home.I. Wireless routers A wireless router is used for accessing the Internet and providing wireless coverage. A wireless router can be used as a forwarder to forward the broadband network signal received from the home wall to nearby wireless network devices (laptops, WiFi-enabled mobile p

Wireless routers are unable to access the reason and the solution, the use of wireless routers more and more people, there will be more and more problems. Along with the development of network technology, the use of wireless network is more and more common, the problem that wireless router can't access the Internet is more and more often encountered. Considering

ARP attack: the culprit that causes transient disconnection and large-scale network disconnection. In a LAN, IP addresses (Layer 3) and Layer 2 Physical addresses (MAC addresses) are converted through ARP. Some devices in Internet cafes, such as routers and computers with TCP/IP protocols, provide ARP cache tables to speed up communication. Currently, many attack software with ARP spoofing uses ARP to attac

Today, with the rapid development of the routing industry, it has become a very important device in networking, and each field is also suitable for its own vrouters. Below we mainly aim at Internet cafe routers, analyze in detail the Networking Solution of the Internet cafe router. In recent years, the new technological revolution represented by the

network can be normal access between the inside. How routers Restrict network speed: Settings that do not allow a computer to surf the internet 1. Set page--Security settings--firewall Settings--Choose to open the firewall, turn on the MAC address filter Two--"Prohibit the Set MAC address list enabled MAC address Internet access." 2. Set page--Security settin

The method for connecting two routers to the Internet at the same time is not just one. You can also use other routing configuration methods. Here we will introduce the fastest method, so that you can do it in a few minutes. I use ADSL to access the Internet. I have two soho routers connected to each other, both of whi

Lightbulb surfing the internet? Researchers use LEDs as Routers Now, WiFi is an essential thing in our life. We use it to read, entertain, work ......, The magic radio waves are carrying data that keeps moving between devices and wireless routers. However, wireless network signals are not ubiquitous. Sometimes users in complex environments, big-sized houses or v

Surfing the Internet makes it necessary for us to deal with broadband routers. However, during our use process, we seldom look at it. Even if the network is faulty, few believe that these faults are related to routers. In fact, a vro is the same as other network devices. When we set or maintain the router improperly, it may encounter various inexplicable faults.

At present, ADSL permeate every corner of our lives, whether it is enterprises, Internet cafes, or home users using ADSL to access the Internet, usually, an ADSL line can only support one computer to access the Internet, however, after using a networking device, you can implement an ADSL line to support Internet access

At present, China Telecom, China Unicom, and China tietong broadband operators in some regions will restrict the Internet sharing of routers to prevent a broadband line from being shared by several households. However, this approach will cause problems for a household with multiple computers or other internet devices. In fact, you can crack this restriction by cl

Using telephone lines, cats, and routers to access the Internet two days ago, I took my laptop to my uncle's house. I heard my uncle say that his router may be damaged by lightning strikes. He previously contacted the carrier China Unicom. After checking that the router is broken, he could use a cat to access the Internet. After a few days, only one computer at h

Routers can connect on the Internet is not the reason why: Router Setup problem; The problem of the network itself; Connect a hardware failure problem such as a device or router. Cause the router can connect, but not on the above three kinds of situations, for users, if encountered this situation, the most important thing is to learn how to troubleshoot problems, to be good at using the elimination meth

This section describes how to set up stable Internet access for D-Link wireless routers. Before giving you a detailed introduction to D-Link wireless router settings, first let everyone know the corresponding parameters in the configuration mode, then we will give a full introduction to Internet sharing and select the most simple solution of using a Broadband Rou

H3C's ER3000 series routers enable small and medium-sized enterprises to access the Internet I. Networking requirements: An enterprise needs to meet the following requirements: 1) China Telecom and China Netcom each access m optical fiber, and achieve the "China Telecom, China Netcom, China Netcom" requirement only ER3260/ER3200 ). 2) Prevent ARP attacks in the LAN. 3) prevent some computers from occu

Question: I use an ADSL Internet, existing two routers, there are 1-way WAN and 4-way LAN port, but there are 5 computers to share the Internet, that is, the first route out after a line into the second route after another point two, to find the route wiring and settings.Answer: This is a more common situation, first of all, to explain the principle:Router 1, lik

Many users reflect their own millet mobile phone can not connect to the router's WiFi network, for everyone encountered problems, sorted out without wiring by the set up methods to share to everyone. This article takes Tp-link tl-wr941n as an example, other routers are basically similar. It is recommended that you initialize the router once before you start the setup. You can restore the default settings in the options, or hold down the reset on the r

Internet Café router with the number of machines, as the name implies, is the number of computer routers can load. The average manufacturer will be in the performance parameter table nominal own router can carry 200 PCs, 300 PCs, but many times the performance of the router and nominal value are very big discrepancy. This is because the number of Internet café

correctly fill in the router's management user name and password to enter the Administration page. If the router is the default setting, its administrative address is: 192.168.1.1; user name and password are: admin 2. Select "Network parameters" → "wan port settings" in the left box, and then select "PPPoE" in the "WAN connection type" in the right box. "Internet account" and "Internet password" to fill

China Unicom broadband I changed the world to the configuration of using routers to access the Internet on multiple computersYou cannot directly enter the account and password provided by China Unicom in the vro. Why do you understand it.First, use "Broadband my world" to access the network, right-click "computer", and select "manage" to go to computer management. There is a Window log under the system tool

In the normal course of Internet access, when the router's WAN can not automatically obtain the IP address, it is often possible to shut down the DNCP service or IP address conflict caused. The following are the main agile fw54r routers to illustrate this problem and the solution: First, talk about the failure of the network situation: The newly bought fast Fast fw54r wireless router, after the WAN line i
