After reinstalling the computer, you can t use the router to access the Internet, I hope the master

What brand of router do you have?

Try to change the DNS, I encountered a situation before, just change the DNS to be consistent with the DNS obtained by the router.

Check if there is a problem with the port or cable, and generally the crystal head of the network cable without a holster is bad.

Under normal circumstances, after entering the router and setting it to pppoe, you can surf the Internet.

You first check whether your router is set to automatically obtain IP, if it is automatically obtained, the local connection of the computer hanging below does not need to set the IP

Depending on which province you are from, it should be no problem to choose the DNSIP of your province to see the preferred DNS!

For DNS around you can get to:

Learn to query.

After reinstalling the system, the settings will be deleted, and the router settings must be set up again! It is recommended that you reset both computers once!

It's you who set it up incorrectly... Use the 360 disconnected first aid kit to complete the repair with one click...

The computer is set to automatically obtain IP and DNS, check whether the local connection is disabled, whether there is an extra local connection, and just leave one.

I don't have a network card driver installed. Install the NIC driver.

Right-click on "Online Neighbors" - Properties" and "Right-click on "Local Connection" - fix "You go try!"

If you confirm that the network card cable is okay and the network card driver is normal, you can try to do this:

Take a look at the network configuration of a computer, including the IP gateway, subnet mask, DNS server. Then manually set the network of B according to this information, and set it to be the same as A except for the IP. If A's IP is yes, B's IP can be set so that the last digit cannot be repeated.

You try it.

Restricted connectivity is usually due to a problem with the network address or gateway settings. You go into the router and see how many IP addresses there are in the address pool in the DHCP service, and it takes at least 2 of your computers to assign to the other.

There are several reasons why your computer can't connect to a wireless router but can't access the Internet

1. The wifi itself is a problem, and the wifi may not be connected normally, resulting in the inability to access the Internet.

2. Router problems, the router may be overheated or damaged.

3. Broadband arrears may lead to inability to access the Internet.

4. The wifi name contains Chinese, which causes some computers to be unable to connect to the Internet.

5. Computer system problems, there may be problems with the system, resulting in connecting to wifi but unable to access the Internet.

Suggested workaround:

1. Use other mobile phones or devices to connect to wifi to try whether you can access the Internet, and rule out the wifi itself.

2. Restart the router to try, or restore the router to factory settings, then dial up the Internet again, and reset the wifi according to the setup wizard, or change to a new router and dial up to connect to the Internet.

3. Contact broadband customer service to confirm whether there is any abnormality in the broadband account, such as arrears, recharge the broadband, and then dial up to connect.

4. If the wifi name contains Chinese, it is recommended to modify it to English or a combination of English and numbers before connecting.

5. If the above reasons are ruled out, it is likely to be a computer system problem for a long time, and it is recommended to restore the factory settings. See if that solves the problem.

When you say good connection, you mean hardware, I don't know if your router is set up? To fill in your broadband account and password on the WAN in the router, and then see if the router's DNS settings are correct, the normal default setting is empty DNS, but sometimes I don't know who has modified it, fill in a DNS that does not belong to your area. See for yourself.

You can open the network connection properties - details to see if the computer has the exact IP and DNS.

As long as the router or switch is powered on, connected locally, and set an IP address, it will be displayed.

What do you use to access the Internet? Dial-up with a broadband connection, or some other dial-up software, or do you have a router set up?

TP-Link's router is not good, I used it in college and changed it twice because of insufficient power supply and frequent disconnections.

Let's change to ASUS.

To access the Internet, you must have a cat with routing function! Then set up a route on the router to automatically dial up the Internet.

Let's see if the router is set up.

For router settings, novices are prone to make mistakes in the following ways:

1. There is no choice of conjecture and PPPOE

2. If you accidentally set the IP address range, it is generally enough to default.

3. The MAC address is not copied and bound.

4. The connection between the cat and the router is abnormal, such as the network cable of the cat is connected to the WAN of the router, and the rest is connected to the computer.

5. The password for surfing the Internet is incorrect.

6. The IP address and DNS of the local connection are set incorrectly (generally you can choose automatic), I hope to give you inspiration and prompts.
