Zoom Connection Unstable? Fix It: Join Multiple Internet Connections Together – Like Starlink, Wi-Fi, 4G, 5G, and DSL – with Speedify
Mid-sentence, Zoom flashes the warning that your internet connection is unstable, and then the audio begins cutting in and out. Zoom shows that message when data stops arriving evenly, usually because you are too far from the Wi-Fi router, sitting in poor cellular coverage, or sharing a home network with someone streaming.
Speedify is an app that spreads your internet traffic over Wi-Fi, 4G/5G cellular, Ethernet, Starlink and satellite internet connections at the same time, so an uneven internet connection is covered by another one. Speedify can only keep you online through a drop when it has two or more internet connections to work with, for example Wi-Fi plus your phone’s 4G/5G cellular. On a single connection, Speedify works as an encrypted VPN and cannot stop that connection from dropping. Keep reading to learn what triggers the unstable warning, how to clear it, and how using Speedify makes it less likely to come back.
Causes of an Unstable Network Connection on Zoom
First of all, the symptoms of an unstable connection in the context of using Zoom include one or more of the following:
- latency
- frozen screen
- poor quality audio and video
- meeting getting disconnected
If you’re connecting to Zoom from work on an enterprise Internet connection, most probably the tech support team is already scrambling to fix it. It doesn’t hurt to give them a nudge anyway.
When you get an unstable connection on Zoom while at home or on the go, then you’ll have to refer to your Internet infrastructure and your ISP. Here are the most popular causes:
- You’re too far away from the Wi-Fi router
- You have poor / slow cellular coverage
- Your network hardware needs an update or a restart
- There are temporary ISP infrastructure issues
- There are peering issues with Zoom servers
How to Fix and Avoid Zoom Connection Unstable Errors
First, is Zoom fully functional? Check out their service status page to confirm.
Then, test your online speed. Is it fast enough for Zoom video conferencing? You’ll need at least 2 Mbps upload and 2 Mbps download. Below that, expect a softer picture; here is how to fix grainy, laggy Zoom video.
Assuming that nothing is wrong with the Zoom service itself, here’s the quickest way to troubleshoot and fix Zoom connection unstable errors:
- Move closer to the Wi-Fi router or, better yet, use a wired Ethernet connection if possible.
- Move around till you get better cellular coverage, if no other connections are available.
- Restart your modem, router and the device you’re running Zoom on (computer, smartphone). You may also update your router’s firmware, if that’s available.
- Check if your ISP is having temporary issues. They should have a status page or at least a social media account to communicate that.
- If you have 2 or more Internet connections available, use them at once. Most likely, you have 4G/5G cellular available on your smartphone, so you can combine that with your home Internet. You’ll need an app that combines internet connections, like Speedify, for that.
How Speedify Performed in Zoom Tests
The Speedify team tested Zoom on a laptop and on a smartphone while running Speedify, simulating bad Internet conditions. The results showed that Speedify was able to keep the average Zoom video call bandwidth on both devices in good range around the target bandwidth. And this happened both in situations where the connections were good and when one of them went bad.
So how does Speedify achieve that? Speedify combines internet connections, which allows you to use multiple Internet connections at once. On your smartphone, Speedify combines Wi-Fi and 4G/5G cellular. On a computer, there’s more flexibility about the number and type of connections.
Speedify also reroutes data when something happens to one of your connections. When you stumble upon a bad Wi-Fi hotspot, or one connection suddenly goes out, Speedify intelligently and automatically reroutes your data through the other available connection(s) in milliseconds and keeps the same public IP address, so the Zoom call keeps going.
The beauty of it is that Speedify does more than just manage your Internet connections. Speedify also encrypts all of the data you send and receive from your device, like a VPN. This helps keep your private information and conversations secure from digital eavesdroppers and cyber thieves.
