[Q&A].

The main reason: the laptop has been connected to the router, but it can't get through to the Internet, there are roughly three reasons: first, your wireless router is not set up; The second is that your router has been set up, but your main line is not plugged into the WAN port of the router (some routers also have Internet written on it); The third is that you have plugged the main line into the WAN port, but the light does not turn on, which means that there is a problem with your main line.

For wireless networks, the connected wireless network is only a local area network, and there is no permission to access the Internet, and the unrecognized network may usually be due to the poor signal of the wireless network near you, a problem with the wireless network settings (such as the IP address configuration is incorrect, and you need to reset it), or a wireless network card driver problem, or a wireless routing problem (reboot to try).

Solution: Right-click on the computer - Properties - Device Manager - find the network adapter - right-click to uninstall it - click on the "Scan for hardware changes" icon in the toolbar above, and restart. Boot.

If you use routing, it is best to reset the router, there is an "advanced option" in the save settings, and the value must be adjusted to 1300-1400 to stabilize! The default seems to be 1480.

I wish you all the best and all the best!

Check and determine if the 'wireless connection' is an automatic IP or fixation, or if you need to bind your Mac. Click on the network icon in the bottom right corner; Open the Network & Sharing Center --- click Change adapter settings; Double-click the 'Wi-Fi' connection icon >> Click Properties >> Double-click Internet Protocol version 4; See if you need to add an IP address or change your IP address here.

If you need to bind a MAC to this wireless environment, you need to go to the routing settings to set it. Different routes have different paths, but the operation principle is the same, and the settings are based on the actual situation.

It is recommended that the router be set dynamic.
