The computer is easy to use when plugged into the main line, but it is not easy to use when plugged

The router is plugged in correctly.

1. The cable out of the cat is connected to the separate hole on the router (not the hole of the chain computer) 2. Plug the four holes in the row on the router into the network cable to connect to your computer - open the network neighbor - right-click the attribute - local connection is enabled.

3. Set the ADSL and password to you in the routing (go down step by step in the setup wizard, and then enter the password given to you by Telecom and click Finish).

4. Look at the running status of the router in this way, and see if the IP on it has been displayed, so that it can definitely be connected.

Are you asking about a router or a lack of broadband?

678 error, it is a broadband connection, the remote server does not respond, that is to say, dial with a cat, the telecom server does not respond, and the number cannot be dialed, so it is not connected to the Internet. In this case, generally if the line is fine, you can turn off the cat, turn it on again after 5 or 6 minutes, redial, and generally dial it.

As for the router, do you mean that the cat can dial up the number normally, the computer can access the Internet through the route, but it can't get on, and it can be connected directly to the cat? Is the router set up correctly?

If the settings are correct, the cat can also dial up the Internet normally, but several machines can't get on through the route, which is estimated to be a broken route.

The router is to be set up, set it up, read the manual, there is an introduction on it!

Check your router settings, there must be something wrong with the settings.

Setting up the problem is a trivial matter. But no matter how small you are, what if you can't do it at all? Let me introduce a method that solves 99% of the problems.

It turns out that the network cable that comes out of the wall can be plugged into the computer to access the Internet normally, now please unplug it from the computer and plug it into the router's lan1, and then find another network cable, one end plugged into the router lan2, and the other end plugged into the computer.

Well, give it a try, now the computer is available for Internet access!

Thank you for your question.

Connect the LAN port of the router and turn off DHCP on the router.

This means that the router is not set up properly, or there is a problem with the router itself, if there is no problem, restart the router and reset the IP.

You have to write your broadband account and password into the router, let the router automatically dial up the Internet, the router's DHCP function should be turned on, otherwise you may not be able to get the IP address when you connect, DHCP is used to allocate IP, DNS is best written,

To use the router, you need to configure and select the corresponding connection mode, such as configuring PPPOE dialing on TPLink WR886N

1. Open the browser, enter, enter;

2. Enter the router password and click OK. (Blank by default) 3. Automatically start the connection wizard and click Next;

4. Select the connection mode that conforms to the actual situation, in this case, the PPPOE dialing mode is selected;

5. Enter the account password provided by the broadband operator and click Next.

6. You can modify the wireless SSID name, it is recommended to select WPA-PSK WPA2-PSK encryption, set the password, and click Next;

7. Click Done.

You try to see if the router can access the Internet, or whether you want to dial up to access the Internet.

If the network cable is plugged into the computer, it can access the Internet normally, which means that the network is fine. And plugging in the router does not work, there are three situations:

1. The router is not set correctly. In the settings of the router, select the correct setting according to the broadband type: enter the settings interface and click "WAN port".

The connection type of home broadband is generally PPPOE, and the Internet account and Internet password are the numbers and passwords provided by the network provider. But there is not this type of broadband:

2. If the router fails, this can only be tried by replacing the router.

First check whether your router is connected correctly, whether it is set up, and some network cables are crossover lines, and the network port of the current router only has 4 reeds (the port of the network cable), so it is also not passable.

The router needs to set up dial-up, write your Internet account and password in the router, and the setup wizard will come step by step.

If you understand the above steps, you still can't get on the Internet if you set it up correctly.

Go to the router settings interface, "Network Parameters.""--"MAC address cloning"--"Clone MAC address" saved the reboot router.

Hello friends:

The network cable is plugged into the router, and because the router has set the account number and password, it will automatically dial up the Internet to surf the Internet. If you don't dial in the network cable, you can't get on the Internet, and you can only access the Internet if you dial up.

Hope it helps, happy to you!

The router is set up, and the network cable to connect to the computer requires dial-up, which is a broadband connection.

You don't have a broadband account logged in to your computer.

The network cable can be plugged into the router, and it can't be plugged into the computer

1. The router can be automatically dialed, and the network cable introduced by the operator can be automatically dialed up to the Internet, but after connecting to the computer, the computer also needs to dial through the dialing program.

2. The computer may have a problem with the network card driver, and the dialer cannot be dialed through the dialer program, so you can reset the dialing software or reinstall the network card driver, which can generally be solved.

The computer is directly plugged into the Internet cable, 1Need.

Dial-up Internet access. Then the router.

It needs to be set to:

PPPoE dialing.

To access the Internet, fill in the broadband account password.

2.No dial-up required, direct access to the Internet. That.

Router settings.

You can use the dynamic IP to access the Internet.

Is the router plugged into the network cable behind the modem or another router?

If the wireless network is used normally, the broadband network connection is normal.

The computer is connected to the router through the network cable, and the use is not normal, then the problem is generally on the wired network or the computer.

The first one may be that there is a problem with the connected network cable and it cannot be connected normally, it is recommended to replace a network cable, and the plugs at both ends of the network cable must be plugged in place.

The second possibility is a computer system problem, such as a DNS hijacking, or a wrong setting, and a problem with the network card driver. It is recommended to update the NIC driver, and if it does not work, reinstall the system, which can generally solve the problem.

If the plug-in route is good, it means that the network cable is good and the network is connected.

Looks like there's something wrong with your computer.

Find someone to help you take a look.

Definitely can't get on, your computer IP should be the same as the IP on the router, the IP on the router has been routed. If you use the main line to surf the Internet, you need to enter your broadband account and password in the broadband connection on the computer or some operators' specific client software, and the IP address is set to be automatically obtained. Your router's current WAN port address is now automatically obtained.

There are two general reasons:

1. Dial-up Internet access, the server side is bound to the MAC address of the network card of the computer you used when you first surf the Internet, and the computer you are using now is not the original one.

2. If your router is a second-level router, then in addition to the MAC address does not match, it means that the IP (DNS) of the local connection is not set correctly.

You can see if the MAC address bound to the router matches the MAC address of the computer. If it's different, it's normal to not be able to access the Internet with the main line.

When using the mainline, you set the IP to be obtained automatically. There is also the possibility of dial-up Internet access.
