Connect PC to Internet Without WiFi Adapter: Easy Ways That Work

If you're stuck without a WiFi adapter and wondering "how to connect a PC to the internet without WiFi", you're in the right place. Many people face this issue when they build a desktop or use an older PC without built-in wireless support. In this post, we’ll explain some working solutions using mobile tethering, LAN sharing, and more. You don't need to buy any extra hardware—just follow these tricks.

📶 Why Your PC Can’t Detect WiFi

Before jumping to the solutions, let's understand why your PC can't connect wirelessly. Most desktop PCs don’t come with built-in WiFi cards. Unlike laptops, they need a USB WiFi adapter or an internal card. If you don’t have one, your PC won’t even show nearby networks. But don’t worry, here are ways around it.

🧰 Method 1: Use USB Tethering from Your Smartphone

This is the easiest and fastest way to get online without WiFi or LAN.

Steps to Use USB Tethering on Windows:

1. Connect your Android smartphone to the PC using a USB cable.
2. Enable Mobile Data on your phone.
3. Go to Settings > Network & Internet > Hotspot & tethering.
4. Turn on USB Tethering.
5. Your PC will detect the phone as a network adapter and connect to the internet.

"USB tethering for PC internet" is a very underrated but powerful trick. It is ideal for temporary access and works even on Windows 7, 8, 10, and 11.

🔌 Method 2: Share Internet Using Ethernet from Laptop

If you have a laptop that can connect to WiFi, you can share that connection with your PC using an Ethernet cable.

Here's how:

1. Connect your laptop to WiFi.
2. Plug one end of the LAN cable into your laptop, and the other end into your PC.
3. Go to Control Panel > Network and Sharing Center > Change adapter settings.
4. Right-click on your WiFi connection and select Properties.
5. Click the Sharing tab and enable “Allow other network users to connect”.

Your laptop now acts as a bridge, and your PC can go online using its internet.

📱 Method 3: Wireless Hotspot to Ethernet via Android OTG

Some advanced users can share Android mobile hotspot to PC using OTG Ethernet adapters. This method is more technical but works great when other options fail.

Requirements:

• Android phone with OTG support
• OTG to LAN converter
• LAN cable connected to PC

Set the mobile as a hotspot provider and use OTG to feed internet through the LAN port into your PC. It's not beginner-friendly, but it’s a lifesaver in some situations.

💡 Other Methods Worth Trying

1. Use Bluetooth Tethering:

Not as fast as USB, but better than nothing. Turn on Bluetooth on your phone and PC, pair them, and use Bluetooth tethering from your phone’s settings. Your PC will use the Bluetooth network for internet.

2. Portable USB Router:

If you have access to a 4G LTE USB modem or router, plug it into your PC. These devices often work without drivers and create instant connectivity. Great for travelers or rural areas.

💭 My Experience (From Cyber Gvs)

I once had a situation where my desktop had no WiFi card and my broadband modem was down. I urgently needed to submit an assignment. I used my Android phone, turned on USB tethering, and within seconds my PC was online. It saved the day!

Later, I even used a LAN cable to share internet from my laptop to my PC. Both methods worked like magic. Now, I always keep a USB cable ready for emergency connections. You should too!
