Zoom is a tool that brings people together and one of the most popular remote work and remote learning tools in the world.

Zoom Meetings syncs with your calendar system and delivers streamlined enterprise-grade video conferencing from desktop, mobile and dedicated Zoom for Home Devices. High-DPI displays are supported in Zoom version 3.5 or higher; Bandwidth requirements. The bandwidth used by Zoom will be optimized for the best experience based on the participant‘s’ network. It will automatically adjust for 3G, WiFi, or wired environments. Recommended bandwidth for meetings and webinar panelists: For 1:1 video calling.

From time to time, Zoom might display various error codes on the screen indicating your connection is not stable. And if your Zoom connection is unstable, you’ll experience video or audio buffering issues, and frequent disconnects.

Fix Zoom Error: Unstable Internet Connection

→ Quick Fix: This error normally appears when you’re in the middle of a video conference. Obviously, you don’t have much time to tweak your settings or look for the culprit. As a quick workaround, if you are using your camera, try turning it off.

In this manner, you can free up precious bandwidth which should preserve the audio and screen sharing quality allowing you to still actively take part in the meeting.

1. Check your network connection

The first thing to do to make sure you have a stable Internet connection is to restart or unplug your modem and router. If there are any pending router firmware updates, install them on your device.

In order to give Zoom access to your full bandwidth, check if there are other devices connected to your network and disable them. Additionally, to further speed up your connection, you can use an Ethernet cable which is known to be more stable and faster compared to a wireless connection.

If you can’t use a cable connection, make sure you’re not too far away from the Wi-Fi router. Ideally, the computer you’re using for Zoom video conferences should be only a few feet away from your router.

Alternatively, you can also switch to a different Wi-Fi channel and test to see if you notice any differences.

After following all these suggestions, check your connection and make sure you meet the bandwidth requirements (ideally, at least 2 Mbps up/down).

Note: Temporary infrastructure issues on your ISP’s side could also negatively impact your Internet connection. Get in touch in your ISP and check if there are any known infrastructure or server problems.

2. Disable bandwidth-hogging programs

If there are other programs running in the background, we recommend disabling them, especially if we’re talking about bandwidth-hogging software such as cloud sync programs, streaming tools, video-sharing programs, and so on.

If you’re using a VPN, disable it and check if you notice any improvements in terms of network stability. Some statistics suggest that using a VPN may slow down your connection by up to 30% or even 50% if you use a VPN server that’s not located in your region.

3. Disable SIP ALG and QOS

SIP ALG or Application Layer Gateway is a tool that many routers come equipped with. Its main role is to prevent router firewall issues. But sometimes, SIP ALG can cause more problems than it fixes, and disabling it is a wise decision.

To disable SIP ALG, follow these steps:

  1. Access your router’s admin page, and go the Advanced Tab or Advances settings.
  2. Then, select Setup and WAN setup.
  3. Locate NAT filtering, and check the option that allows you to turn off SIP ALG.
  4. Restart your router and check if Zoom still detects the connection is unstable.

These instructions may vary depending on your router model. On some routers, the SIP ALG feature can be found under firewall settings. For detailed instructions, go to your router manufacturer’s support page.

Other users suggested that turning off QoS (Quality of Service) may also help. As a quick reminder, QoS is a common router tool that prioritizes traffic.
