Problem description

When we use a router to access the Internet, we sometimes encounter the following situation: the router appears to be working normally, but cannot access the Internet. This kind of problem is very disturbing because we cannot use the Internet normally. This article will introduce some methods to solve this problem.

Check the connection

First, we need to check whether the connection to the router is normal. Please ensure the following:

1. Check whether the power adapter is plugged in and whether the power supply is powered on.

2. Check whether the network cable connection of the router is firm, and make sure that the network cable is not loose when plugged into the port of the router and computer (or other device) .

3. Check whether the connection between the broadband modem (if any) and the router is normal. Make sure the network cable is plugged into the correct port.

Restart the router and device

If there is no problem with the connection, we can try to restart the router and device. Follow these steps:

1. Turn off the network connection on your computer (or other device).

2. Unplug the router's power adapter, wait about 30 seconds, and then plug it back in.

3. Wait for the router to fully boot, then open a network connection on your computer (or other device).

Check the IP address

If the problem persists after restarting the router and device, we can check whether the IP address is set correctly. Please follow the steps below:

1. Open a command prompt window on your computer (press Win key + R, enter "cmd" and press Enter).

2. Enter "ipconfig" in the command prompt window and press Enter.

3. Find the network adapter connected to the router and check whether its IP address is a private IP address (usually starting with 192.168).

4. If the IP address is incorrect, you can try to refresh the IP address by using the following command: Enter "ipconfig /release" in the command prompt window, and then enter "ipconfig /renew".

Check DNS settings

If the IP address is set correctly, but you still cannot access the Internet, we can check whether the DNS settings are correct. Please follow these steps:

1. Open Control Panel on your computer and select "Network and Internet".

2. Select "Network and Sharing Center" and then click "Change Adapter Settings" on the left.

3. Right-click the network adapter connected to the router and select "Properties".

4. In the pop-up window, double-click "InternetProtocol Version 4 (TCP/IPv4)".

5. Make sure the "Obtain IP address automatically" and "Obtain DNS server address automatically" options are checked.

Check the firewall and Security Software

Sometimes, firewalls and security software may block your router's connection to the Internet. Please follow these steps:

1. Temporarily turn off the firewall and security software on your computer .

2. Try to reconnect to the Internet.

Contact the network service provider

If the problem still persists after the above steps, it may be caused by the network service provider problem. You can try to contact the network service provider, report your problem to them, and seek their help and support.
