When the router has an exclamation mark on the connection icon, it usually means the router cannot connect to the internet or the connection quality is poor. This problem is usually caused by the following reasons:

• Network failure: Sometimes, the internet service provider may experience network failures, causing the router to be unable to connect to the internet.
• Router setting errors: If you recently changed the router settings, it may cause the router to be unable to connect to the internet.
• Signal interference: If you are using a wireless router and there are other wireless devices or interference sources nearby, it may cause the router to be unable to connect to the internet.
• Device issues: Sometimes, router hardware failures or firmware issues may cause the router to be unable to connect to the internet.

If the router cannot connect to the internet, you can try the following solutions:

1.Restart the router: You can unplug the router and wait a few seconds before plugging it back in or press the reset button on the router to restart it. This can solve many temporary network connection problems.（Click to view:How to properly reboot my router?）

2.Check the router settings: Log in to the router's admin interface to check the router's settings to ensure it is correctly configured, including IP addresses, DNS servers, and other network settings. Here, it is particularly important to note that the IP address segment should be set between 192.168.1.2-192.168.1.254 and you 'd better not allocate multiple computers the same IP, as this can cause IP conflicts and prevent internet access.（Click to view:How to set up a router to access the Internet）
