The master comes in, and the computer can t access the Internet.

In your narrative, there are two rooms and two computers. I don't know, what is the relationship between these two rooms you call it? Is it a neighbor? Are they two places? Is it the same route? Is it two cats?

First, see if the network settings of your computer and laptop are the same. After everything is set to the same, see if the computer can connect to the network.

Second, if the two rooms use the same route, it is likely that the IP address is bound. You can restart the router or set it up again according to the router manual.

Third. If you don't have a separate router, there may be a problem with the IP location. See if your cat has a routing function, and reset the cat according to the manual. Pay attention to the setting of your local IP and do not exceed the scope of the gateway.

Fourth, there is a problem with your computer's gateway settings.

Is the router set up MAC address binding?

Suggestions: 1. Restart the router.

2. Change the position of the network cable plug to see if the LAN port is connected incorrectly;

3. Open the online neighbor, and change the IP address to automatic;

4. Disable the online neighbor and then turn it on.

A toss should be fine!

whether the addresses are conflicting, and if there is a conflict, reassign the address;

2.Whether the network cable plug is in bad contact with your computer, it is good to be in contact with other computers, and it is not in good contact with your computer. I've had this problem before.

I'm going to say they've already said it, follow their steps step by step to test the handle.

The IP address is set to be obtained automatically.

The IP is incorrect, you go into the router and look at the IP

There are many reasons why you can't get online, so check them one by one:

1.From the source, there is an indicator light on the "cat", which is generally marked as ADSL or DSL, to observe whether the light is always on, and it is normal if it is always on;

If it is flashing, it means that there is no signal;

If the indicator light is not on, it means that there is a problem with the external line or the cat itself, and let the broadband management office send someone to check or replace the cat.

2.Damaged or broken network cables, rusty or wrong connections on the crystal head will cause abnormal or simply unable to access the Internet. Solution: Replace the network cable or redo the crystal header.

3.Check whether the NIC driver is normal, if there is a question mark or exclamation mark on the NIC icon on the page, you need to reinstall the NIC driver.

4.If the router is not set to automatically obtain the IP, the Internet Protocol must fill in all the information, especially the DNS server.

First, it can be repaired through the computer manager network repair function.

1.Open PC Manager and click Toolbox.

2.Locate the Network Repair Tool.

3.Click "Fix Now".

2. You can also use commands to reset the network.

1.Find "Run" in the Start menu2Then type cmd3 into it

In the command prompt that appears, type "netsh winsock reset.""Press the "Enter" key.

It takes effect after restarting the computer.
