ADSL and 4G/5G Bonding – No Need for Dedicated Router
To combine ADSL and 4G/5G cellular without buying a dedicated router, run your ADSL line and a 4G/5G cellular connection at the same time. Speedify is an app that combines two or more internet connections at once, such as ADSL and 4G/5G cellular, so you get faster uploads and downloads and stay online if one connection drops out. On the ADSL line alone, Speedify works as an encrypted VPN and cannot make it faster. Speedify runs on Windows, macOS, iOS, Android and Linux. Download Speedify and start with a free account that includes 5 GB per month.
Combining ADSL and 4G/5G Cellular for Speed, Stability and Security
If you live in a remote area, or ADSL is the only wired internet available where you live, you are not the only one stuck with a slow line. You can still get more out of it by using your phone’s 4G/5G cellular connection together with your existing ADSL line. Speedify combines the two in a few minutes.
Requirements
- Speedify, with a free account (5 GB per month on Windows, macOS, iOS and Android) or a paid subscription, which Linux needs.
- A 4G/5G cellular connection, either from your mobile phone or a USB cellular dongle.
6 Steps to Combine ADSL and 4G/5G Cellular with Speedify
Here’s what you have to do:
- Make sure you’re connected to your ADSL Internet, either via wired Ethernet or Wi-Fi. For best results, use the wired Ethernet connection, because Wi-Fi signal strength varies.
- Setup your 4G LTE / 5G cellular connection: either tether your smartphone via USB or connect a USB cellular adapter. See instructions below on tethering:
- Start Speedify and sign in with your Speedify account. Speedify will detect your active ADSL and 4G/5G cellular internet connections and show them on the screen.
- Choose a server for Speedify to connect to and combine the DSL Internet link with your tethered phone connection. By default, Speedify connects to the fastest server, but you can choose a specific location as well; some location-restricted sites may work through a server in another country.
- Set the 4G/5G cellular connection to Secondary priority and set a daily or monthly data cap. Speedify stops using the cellular connection once it reaches the cap, so you do not pay for going over your plan. If you have an unlimited data plan, set the 4G/5G cellular connection priority to “Primary” instead.
- Enjoy faster internet: Speedify combines your ADSL line with your 4G/5G cellular connection and uses the bandwidth of both. When both connections light up in the Speedify interface, they are online and Speedify is combining them.
Speedify Encrypts ADSL and 4G/5G Traffic Like a VPN
Speedify is more than a way to use and manage ADSL and 4G/5G cellular internet connections together on your computer. Speedify also encrypts your traffic like a VPN, and with ADSL and 4G/5G cellular combined, the encryption won’t slow your device down. Encryption protects you from the risks of an unsecured public Wi-Fi network.
Speedify is also a no log VPN service: it does not keep logs of your browsing or sell your data to other companies.
Faster, more reliable internet and encryption come together in one app that takes a few minutes to set up.
If you need faster ADSL internet, add a 4G/5G cellular connection on your computer and combine the two. Get started with Speedify today!
