How Windows determines the connection priority
Windows typically connects to the network in this order:
1. Ethernet
2.wi-fi
3. Mobile Broadband
When you connect to the new Wi? Fi network, the network is added to the list, and Windows will connect to it when the network enters the range. If you connect to a different Wi-Fi network within the scope of the first network, Windows will prioritize the second network between the first and second networks.
Mobile broadband networks are handled differently. When Wi is present in the range? Fi network, if you manually connect to a mobile broadband network, the mobile broadband network is preferred only during that session. The next time you enter the range of these two networks, will you prefer Wi? Fi network. This is because mobile broadband networks are typically metered.
If you want to force a PC on a mobile broadband network and Wi? Select a mobile broadband network between FI networks, tap or click Wi in the list of networks. Fi network, and then click Disconnect. In this way, Windows will not automatically connect to the Wi? Fi network.
