USB Cellular Adapter on Ubuntu: Combine 4G/5G and Ethernet in Speedify

Optimize Ubuntu Bandwidth and Latency: Combine Ethernet with 4G/5G USB Dongle

You can use Ethernet and a 4G/5G USB cellular adapter at the same time on Ubuntu Linux. Speedify is an app that combines two or more internet connections at once, such as Ethernet and a 4G/5G cellular adapter, so you get faster downloads and uploads and stay online if one connection drops out. With only one internet connection, Speedify works as an encrypted VPN and cannot make that connection faster or stop it from dropping. The steps below show how to connect both to your Ubuntu computer and let Speedify use them together.

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 a USB Cellular Adapter with Ethernet on Ubuntu Linux Using Speedify

Step 1: Connect to Ethernet

Connect an Ethernet cable from your router or modem to the Ethernet port on your Ubuntu computer. If your computer has no Ethernet port, use a USB to Ethernet adapter. Ubuntu starts using the Ethernet connection on its own, and the system menu at the top right shows it as a wired connection.

Step 2: Connect and configure your USB Cellular Adapter

Note: Before you buy or connect a USB cellular adapter, check that it works with your computer and with Linux. Some adapters need software or drivers from the manufacturer.

Connect your USB cellular adapter to a USB port on your Ubuntu computer. It usually shows up in the system menu as a wired connection.

Some cellular adapters need the manufacturer's dialer software to connect to the internet, so follow the manufacturer's installation and setup instructions.

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 cellular sharing 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.
