How to Connect a PC to the Internet Without Wi-Fi or Ethernet

Not having access to Wi-Fi or an Ethernet cable doesn’t mean your PC has to stay offline. Whether your network adapter is broken, you’re traveling, or your router is temporarily unavailable, Windows PCs can still connect to the internet using alternative methods.

In this guide, we’ll walk you through all the practical ways to connect a PC to the internet without using Wi-Fi or Ethernet, along with step-by-step instructions for each method.

Ways to Connect a PC to the Internet Without Wi-Fi or Ethernet

Below are the most reliable options. The best method depends on the devices and connections you have available.

1. Use Mobile Hotspot via USB Tethering (Most Reliable)

If you have a smartphone with mobile data, USB tethering is one of the fastest and most stable alternatives.

What you need:

  • A smartphone with mobile data
  • A USB cable (phone → PC)

(Android):

  1. Connect your phone to the PC using a USB cable
  2. Open Settings on your phone
  3. Go to Network & Internet > Hotspot & tethering
  4. Enable USB tethering
  5. Windows will automatically detect the connection

(iPhone):

  1. Connect the iPhone to the PC using a USB cable
  2. Open Settings > Personal Hotspot
  3. Enable Allow Others to Join
  4. If prompted, trust the computer on your iPhone

Your PC will now use your phone’s mobile data as an internet connection.

2. Use Mobile Hotspot via Bluetooth

If you don’t have a USB cable, Bluetooth tethering can work—though it’s slower than USB.

  1. Turn on Bluetooth on both your phone and PC
  2. Pair the phone with your PC
  3. On your phone, enable Bluetooth tethering
  4. On Windows, connect to the phone via Bluetooth network

This method is suitable for light browsing and messaging.

3. Use a USB Mobile Broadband Dongle (4G/5G)

A USB internet dongle (also called a data card) provides direct cellular internet access.

  • A USB 4G/5G dongle
  • An active SIM card with data
  1. Insert the SIM card into the dongle
  2. Plug the dongle into your PC
  3. Install drivers if prompted
  4. Connect using the software provided by the dongle

This is a good long-term solution if you frequently lack Wi-Fi access.

4. Use Another PC’s Internet via USB or Ethernet Sharing

If another PC nearby has internet access, you can share its connection.

Internet Sharing via Ethernet

  • Connect both PCs using an Ethernet cable
  • Enable Internet Connection Sharing on the connected PC
  • Your PC will use the shared connection

Internet Sharing via USB (Advanced)

  • Requires driver support and configuration
  • Mostly used in IT or testing environments

This is useful in offices or labs.

5. Use Public Internet via Captive Portal Devices

Some environments (hotels, offices, campuses) offer internet access through:

  • USB-based network adapters
  • Docking stations with internet passthrough
  • Enterprise authentication tools

If available, connect using the provided hardware or credentials.

6. Use Offline-to-Online Transfer (Temporary Solution)

If you only need updates or files temporarily:

  • Download files on another device with internet
  • Transfer them using:
    • USB flash drive
    • External hard drive
    • Phone storage

This doesn’t provide live internet but helps in emergencies.

7. Fix Missing Network Drivers (Important Check)

Sometimes it appears you have no Wi-Fi or Ethernet, but the real issue is missing drivers.

  1. Open Device Manager
  2. Expand Network adapters
  3. Look for:
    • Unknown devices
    • Yellow warning icons
  4. Install drivers using:
    • USB transfer from another PC
    • Manufacturer’s website

After installing drivers, Wi-Fi or Ethernet may start working again.

Wrapping Up

With that, we wrap up our complete guide on how to connect a PC to the internet without Wi-Fi or Ethernet. While wireless and wired connections are the most common options, alternatives like USB tethering, mobile data dongles, and shared connections can keep you online when standard methods aren’t available.
