How to Use a 4G/5G Dongle and Wi-Fi at Once on Windows PC with Speedify

Take Advantage of Wi-Fi and a 4G/5G Cellular Dongle for Faster, More Reliable Internet

Want faster upload and download speeds and more reliable internet on your Windows PC? Run Wi-Fi and a 4G/5G cellular dongle at the same time.

Speedify is an app that combines two or more internet connections at once – such as Wi-Fi and a USB 4G/5G cellular dongle (or a tethered phone) – so you get faster uploads and downloads and stay online if one connection drops out.

Speedify is the only app that joins together your Starlink, Wi-Fi, 4G / 5G cellular, wired, and even your friend’s phone signals – and turns them into one ultra-fast and super secure link that keeps you all connected for the best possible live streaming, video calling, or just posting to your favorite app.

Speedify can join any number or combination of Internet connections and will intelligently distribute your online traffic among them for optimal performance. Plus, if you get disconnected from one of your connections in the middle of an important video call or file transfer, Speedify will seamlessly failover to your other working Internet connection(s) without skipping a beat.

NOTE: For best results, use Internet connections from different sources. In general, joining the same upstream network multiple times (such as the same router via Ethernet and Wi-Fi) will not improve performance.

3 Steps to Join a USB Cellular Adapter and Wi-Fi at Once on a PC

Step 1: Connect to Wi-Fi

Verify that your Wi-Fi is enabled on your PC and connected to a network.

Click on the Wi-Fi symbol in the lower right corner of the taskbar (systray). If you’re not already connected to a Wi-Fi hotspot, turn on Wi-Fi by clicking on the tile in the lower left side of the pop-up menu then select your desired network. Keep in mind, private networks may require you to enter a password before connecting.

Step 2: Connect your USB Cellular Adapter to your PC

Connect your Cellular Adapter to a USB port on your PC. Some Cellular adapters require the use of proprietary dialer software to connect to the Internet. Be sure to follow the manufacturer's installation and operating instructions closely.

In order to verify that your cellular connection is active, click on the computer / Wi-Fi icon in the lower right area of the taskbar (systray) and check to see if a “Cellular” tile shows up.

Don’t have a USB Cellular Adapter? You can also use a tethered iPhone/iPad or Android device!

Step 3: Download and Install Speedify

Last but certainly not least, download and install Speedify. Once running, Speedify will automatically detect any available Internet connections and join them together for increased speed, security, and stability.

Need to keep several devices connected in areas with limited or spotty network coverage, like event venues, remote locations or when traveling? Get consistent and uninterrupted online activity for all your devices using Speedify's Pair & Share functionality, which allows you to share cellular data between multiple devices wirelessly.

By pairing devices, you can effectively distribute your cellular connection across them, improving overall performance, especially when other network options like Wi-Fi may be slow or unstable.

You can manage settings, view statistics, and even apply limits to individual connections by either clicking/tapping on them from the Dashboard or by navigating to the desired connection through the main Settings menu.

Speedify will work quietly in the background to optimize performance including prioritizing streaming web traffic to avoid stuttering, buffering and disconnects.

Whether at home, work, or on-the-go, Speedify is the only VPN that makes your online experiences faster, more reliable, and more secure.
