How to Combine Wi-Fi with a USB Cellular Adapter on Ubuntu Linux

Boost Bandwidth and Reduce Latency on Ubuntu by Combining 4G/5G Cellular Dongle with Wi-Fi

In this article, we are going to introduce you to Speedify, the channel bonding VPN and walk you through the steps to combine Wi-Fi with a 4G or 5G USB Cellular Adapter on your Ubuntu Linux computer.

Speedify is the only app available for all major platforms - Windows, MacOS, Linux, iOS, Android and OpenWrt - that combines your 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 bond 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 Combine Wi-Fi with USB Cellular Adapter on Ubuntu Linux Using Speedify

Step 1: Connect to Wi-Fi on your Ubuntu Linux computer

Click on the arrow in the top right corner (also known as the System Menu) then Wi-Fi > Select Network and choose your desired network. Keep in mind, private networks may require you to enter a password before connecting.

Step 2: Connect and configure your USB Cellular Adapter

Note: Before purchasing or connecting a USB Cellular Adapter, be sure to verify that it is compatible with your specific hardware and/or operating system. Some devices may require additional software or drivers from the manufacturer.

Connect your Cellular Adapter to a USB port on your Ubuntu computer. It will most likely appear in your System menu as a “Wired Connection.”

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.

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 combine them 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.
