Setting up a Windows laptop to receive a signal
operating system Windows 10 and 11 has powerful tools for managing network connections. Typically, the laptop automatically detects available Wi-Fi networks. Click the network icon in the system tray, select the name of your access point, and click "Connect." The system will ask for the password you set on your smartphone.
If automatic connection does not occur, it is worth checking the network adapter settings. Click Win + R, enter the command ncpa.cpl and press Enter. In the window that opens, find the wireless connection, right-click it, and select "Properties." In the list of components, make sure the protocols are checked. Internet Protocol version 4 (TCP/IPv4).
Sometimes the problem lies with static IP addresses entered manually. In the IPv4 protocol properties, select "Obtain an IP address automatically" and "Obtain DNS server address automatically." This will allow the router (your phone) to automatically assign the correct parameters for local network.
| Parameter | Recommended value | Description |
|---|---|---|
| IP address | Automatic (DHCP) | The address is assigned by the access point |
| Subnet mask | Automatically | Determines the size of the local network |
| DNS server | Automatically | Converts domain names to IP addresses |
| Gateway | Automatically | Internet access address |
Troubleshooting connection issues on macOS
Users MacBook And iMac You may also need to configure it manually. In macOS, you can manage networks through System Preferences → Network. If the Wi-Fi icon is yellow or red, click the built-in "Diagnose" button, which will attempt to automatically find and fix the configuration error.
