Transferring Large Files on Slow Internet? Use Speedify to Speed Up File Transfers by Combining Wi-Fi, Ethernet, Starlink, 4G/5G Cellular and Others

Reliable File Transfer over Slow Internet Connections Using Speedify to Combine Starlink, Wi-Fi, 4G / 5G Cellular and Others at Once

A large file is anything big enough that you start watching the progress bar, and on a slow connection that transfer will also be the thing most likely to fail part-way and start again.

Speedify is an app that spreads the transfer across every internet connection you have – Starlink, Wi-Fi, 4G/5G cellular data, Ethernet – so it moves faster and survives one of them dropping.

Keep reading to see why file transfers are slow on your network, five steps to move large files over a slow connection, and how combining connections helps.

Why Is File Transfer Slow Over My Network?

Your large file transfer usually takes a lot of time because of:

  • the speed and reliability of your Internet connection, which determines how soon a large file will be downloaded or uploaded
  • where you’re downloading from / uploading to – if you’re transferring to a server on the other side of the world, data goes through many nodes. Also, if you’re using a popular service – e.g. web file transfer, torrents, etc. – their speeds can be limited by the number of users using them at that time. That’s why many of these have “premium” plans, so you can get priority over the free users.

Whatever the reason for the slow file transfer, you should make sure that nothing on your side is limiting the speed or reliability of the upload / download.

5 Steps to Transfer Large Files over Slow Network

What can you do when you see slow file transfer over the Internet? Here are 5 steps:

  1. Test your Internet speed. Go to speedtest.net or fast.com and run a test. Is it close to what your ISP is supposed to provide?
  2. If not – get into the usual slow Internet routine fix: restart your modem / router, your device, move closer to the router, use wired Ethernet etc. and test your speed again. Try these tips before contacting your ISP.
  3. If there’s no issue with your connection speed, but your large file transfer is still slow, your speed could be throttled by your ISP. Connect to another network or use a VPN to avoid ISP throttling.
  4. If there’s no throttling either – bummer! That means there’s a limitation on the way to where you’re downloading from / uploading to. You can change the service you’re using for the large file transfer (e.g. wetransfer, etc.) or try another connection in hope for better peering.
  5. Still seeing no improvement on the transfer rate? Try to use 2 or more connections together at once on your device – channel bonding / link aggregation. A bonding VPN like Speedify is something you should consider to transfer large files over slow networks, whether at home, at the airport, in the park, etc.

Speedify Helps You Transfer Large Files over Slow Network Connections

As a fast bonding VPN, Speedify acts like a power-up for your device when transferring large files, streaming and doing any bandwidth-heavy online activity. Instead of only using a single Internet connection at a time, Speedify allows your device to use all of your Internet connections at the same time. You’ll get more bandwidth and more stable downloads and uploads.

Speedify constantly monitors the quality of your Internet connections. If one of them becomes unreliable, it’ll automatically reroute data through through the other(s) until it is available again.

Moreover, it automatically recognizes audio and video streams, and provides quality of service (QoS) by prioritizing streams over other traffic. Web browsing and software updates can’t mess up your calls and live streams.

Try Speedify when uploading or downloading large files on slow network connections and you’ll see the difference!
