  7. Boot up and install drivers: Turn on the PC and install the necessary drivers if they do not install automatically.
  8. Join your Wi-Fi network: Select your network from the available list and enter the password.

7. Option 3: Dedicated Mobile Hotspot Devices

A dedicated mobile hotspot is a small, portable device that connects to a cellular network and broadcasts a Wi-Fi signal. Your desktop can then connect to this signal just like it would connect to a home router.

When a Mobile Hotspot Makes Sense

  • You do not have access to a traditional home internet connection.
  • You need a temporary or backup internet solution.
  • You frequently move your desktop between locations.

Limitations to Consider

Mobile hotspots depend on cellular coverage and data plans. Speeds may vary, data caps can be restrictive, and latency is often higher than with a fixed broadband connection. For this option to work, your desktop still needs a Wi-Fi adapter (USB or PCIe) to receive the hotspot signal.

8. Option 4: Using Your Smartphone as a Hotspot

If you need a quick, temporary answer to How to Give My Pc Wifi? and you already have a smartphone with a data plan, you can use your phone as a mobile hotspot. This method is convenient in a pinch but is not ideal as a long-term primary connection for most users.

  2. Set a network name and password: Choose a secure password to prevent unauthorized access.
  3. Connect your PC: On your desktop, select the phone’s hotspot name from the Wi-Fi list and enter the password.
  4. Monitor data usage: Streaming, downloads, and updates can consume mobile data quickly, so keep an eye on your plan’s limits.

USB Tethering Alternative

If your desktop does not yet have a Wi-Fi adapter, you can often connect your phone to the PC with a USB cable and enable USB tethering. This shares the phone’s internet connection over the cable and can be a useful stopgap until you install a dedicated Wi-Fi adapter.

9. Option 5: Wireless Bridge or Old Router as a Receiver

Another clever solution is to use a wireless bridge or repurpose an old router to receive Wi-Fi and pass the connection to your desktop through an Ethernet cable. This approach lets your PC stay wired while still benefiting from a wireless link to your main router.

How It Works

A wireless bridge connects to your existing Wi-Fi network and provides one or more Ethernet ports. You plug your desktop into the bridge with a standard Ethernet cable. From the PC’s perspective, it is using a wired connection, but the bridge handles the wireless communication behind the scenes.

Steps to Set Up a Wireless Bridge

  1. Obtain a compatible device: Use a dedicated wireless bridge or a router that supports bridge, client, or repeater mode.
  2. Configure the device: Follow the manufacturer’s instructions to connect the bridge to your main Wi-Fi network.
  3. Connect your PC: Run an Ethernet cable from the bridge to your desktop’s network port.
  4. Test the connection: Confirm that your PC can access the internet reliably.

This option is especially useful if you want to avoid installing internal hardware or if your desktop has trouble with USB Wi-Fi drivers.
