The laptop has been connected to the wireless network at home, but it still can t be connected to th

xx indicates that it is not connected to the wireless router before, if it can be connected before, please turn off the wireless router and turn it on again.

Got it set? The computer and the wireless router can also be connected when there is no external line, so whether you can access the Internet or not has little to do with the wireless router connection, if the external connection inside and outside the router is normal, then you have to see if your IP or DNS will not have any other problems except these two.

Generally, if you encounter such a problem, you can set the IP address to be obtained automatically, then check the account password and re-enter it.

This is because the broadband has not been dialed up yet. You can go into the router, reboot the router, and wait for a little more and you're done.

Are you connected to a wireless router? If you are connected but cannot access the Internet, it is possible that the router cannot connect to the external network, try to enter the router to see if the Wi-Fi is not connected.

Hello, the network is connected does not mean that it is OK, the network connection can only mean that your computer's wireless network card and your wireless router have established a connection, and the computer must automatically obtain the IP address or set the correct fixed IP address to access the Internet (generally you let it automatically obtain the IP address).

Now you don't automatically get the IP address, it is very likely that there is a problem with the settings of your wireless router, and you must turn on the DHCP function in the wireless router, otherwise the computer will not be able to automatically obtain the IP address.

You'll have to go into the router and have its DHCP function turned on, and you'll have to give it a pool of IP addresses (i.e., so that your computer can get the IP addresses in this range).

Finally, you need to make sure that the computer network card is set to automatically obtain the IP address.

The condition of the network is that the router must be able to access the Internet, that is, it is connected to the public network, and the computer is connected to the wireless router in order to access the Internet.

The wireless router cannot be connected to the public network for the following reasons:

1. The routing setting is incorrect, you can connect to the routing through the computer wired, and if you can access the Internet, the setting is correct.

2. The external line is plugged in incorrectly, and the outer line (the outgoing line of the cat) is connected to the WAN port of the router.

3. If there is a fault in the external line, the network company provides services.

Does it show a small yellow exclamation mark?

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

2. Broadband arrears may lead to inability to access the Internet;

3. The Internet Explorer has been maliciously modified;

4. The network cable interface is loose;

I've come across it too.

But I tested it with bt3, and the other party's date is 0, which means that he is not connected to the Internet.

In other words, he only opened the route but did not connect to the Internet, so even if the signal is good, it is impossible to access the Internet.

Restart the router, in the connection, confirm that the network connection is successful, if you can't connect to the network, open the control panel - check the network status and tasks - open the network settings - click on the properties, check all the options that are not checked - confirm; If that doesn't work, change the IP address and change it to auto-equip.

Are you sure the settings are right? You can set whether you want to choose static or dynamic or adsl virtual and real dialing.

My computer has also been unable to connect to the wireless network, and I can't access it even if I change the system. I don't know if you show that the wireless network is turned off, if so, you can try the fn key + on the computer plus that signal key. You may not recognize the signal key, mine is F2.

It's hard to say that it's just an antenna icon, you go and try it. Hopefully it does.

Reinstall the driver. and reconnect.

Check the firewall settings to see if the IP addresses it allows access to have been tampered with, and try the above methods to see if they can help you.

This router should not be connected to the outside, so your book shows that it has been connected (in fact, it is only connected to the router), it is recommended that you check the router and the external network connection to see if the cable is unplugged or loose.

If there is a problem with the IP, gateway, and DNS settings, it is OK if the general settings are fine.

Try reinstalling the wireless card driver, or the wireless password is wrong.

Your wireless settings aren't right.

If a small exclamation mark is displayed, it may be that your router is not connected to the network cable, and if it is confirmed that the connection is normal, it is a network configuration problem!

Open the Network and Sharing Center

Click on the properties in the lower-left corner (circled in the image).

Restart the laptop and wireless router at the same time. Because it is possible that your notebook has logged in multiple times and the route is not successful.

In the wireless connection properties of the laptop, the preset IP, gateway and DNS are incorrect.

Please select Auto-Acquisition.

Or fill in the correct IP, gateway, and DNS.

Change your computer's IP address to get it automatically.
