There are frequent exclamation marks on the wireless network at home, or there is no exclamation mar

Call ** to the carrier, or check the router.

Restart the wifi. Then the steps are as follows:

1. Take OPPO K3 as an example, find the settings on the desktop, and click to open the settings page;

2. Find and turn on WLAN in the settings page (in order to ensure personal privacy, some areas are coded);

3. Find and click the WLAN details icon on the right side of the connected WiFi;

4. Find and click the "Remove this network" option;

5. Finally, re-enter the wifi password to connect to this wifi.

Turn off the router and the modem again and start it again, preferably after turning it off and waiting for about 15 minutes before starting it again.

If it still doesn't work, then you have to find a broadband service staff to solve it.

Unplug the router switch and reboot it, but don't reset it.

Since the landlord mentioned that only his mobile phone can't access the Internet,It can basically be ruled out that it's a problem with the setting of the router.,It should be a setting problem on the mobile phone.,Look at your interface should also be a Huawei mobile phone.,Provide a few ways for the landlord to try whether it works:

Go to the wifi settings page, click on the wifi you have linked, and select "Do not save". This disconnects, and then re-enter the password to connect to the wifi and see if you can surf the Internet normally.

If the above method doesn't work, restart the phone and try again, be careful not to directly select "Restart", point to shut down, then turn it on again, and try again.

Landlord, you try it according to the above method first, if it still doesn't work, you need to provide more information, including screenshots of the mobile phone wifi connection page (IP allocation, etc.) and router model, etc., to see how to further deal with it.

Above, I hope it will be helpful to you.

1. First unplug the power of the wireless router, wait for a minute, turn on the power again, restart the wireless router, and then see if the wireless network is available. And if the problem persists, keep reading. 2. Check whether the network cable is connected to the router; 3. Log in to the router management interface, check whether the internal dialing of the router is normal, usually we log in to the router management interface, and you can see the router running status at the bottom.

Let's take a look at the WAN port status of the router management interface and the WAN port traffic statistics, if it can be seen, the PPPoE dial-up connection has not been connected, and it can be seen in the acceptance column of the WAN port traffic statistics that the traffic accepted by the router is 0, so far it can be basically judged that it is a network problem, the author then contacted the network provider, and then was told that the network line was faulty, and it was being repaired, and it was estimated that it could be restored after half an hour, so far the problem was successfully found. 4. If you are judging that there is no problem with the router dialing, that is, the above WAN port status and WAN port traffic statistics are normal, and the wireless network cannot be connected, you may wish to connect the network cable directly to the computer and try whether the dialing is available.

1. First of all, if a yellow exclamation mark appears on the wireless network, don't smash the computer or router in a hurry. First use win7's built-in network diagnosis troubleshooting,Solve it to see what's going on,You can right-click on the wireless network first。

2. The problems raised cannot be solved with their own solutions. Let's see if it's a router problem. Restart the router, directly unplug the power supply, wait for more than ten seconds, turn on the power supply, and then connect to see if the wireless network can be used.

Sometimes it's just a small crash inside the router, and that's fine.

3. Check whether the connection between the cat and the router is intact, this is very important, the router is on, but this means that there is no network, so a small yellow exclamation mark appears. If there is, fix it.

4. A yellow exclamation mark appears, log in to the router management interface, and generally enter it in the address bar in the browser or. Then you will see the running state, if it appears: the traffic accepted by the router is 0, it is basically a problem with the network operator, call ** to the network operator, report for repair.

If the call is fixed on their side, try restarting the router.

If you see an exclamation point when you're connected to a wireless network, your device is connected to your wireless router but can't access the internet. Here are some of the possible causes and workarounds for the issue:1

Confirm that the wireless router is working properly: First check that the router is connected to the internet. You can try disconnecting the power supply and restarting the router and making sure that all connections are correct.

You can test whether the wireless network is available from other devices. 2.Check your network settings:

Check that your device's network settings are correct. Make sure the wireless network settings on your device are correct, including the SSID and password. If you're not sure, you can try forgetting the network and reconnecting.

In this case, confirm that your device's IP address is set correctly. You can try changing your network settings to get an IP address automatically. 4.

Check your firewall settings: Check if you have a firewall or security software enabled on your device. A firewall or security software may block a wireless network connection.

5.Untroubleshoot your network router throttling: If your wireless router has features like Mac address filtering or maximum connection limits enabled, you can try disabling those features in your router's settings.

If the above methods do not resolve the issue, we recommend that you contact your network administrator or contact the device manufacturer.
