We have been experiencing several Zoom meetings over the last several weeks that have been getting "unstable network connections" and freezing video and audio. We had not been experiencing this for the last several years here in the office with multiple calls happening every day. Our internet connections speeds have remained very fast and showing no issues during the same time these zoom issues occur.
Is there something we should look at on our Network Firewall that could be impacting this? We recently did update our Firewall on our network. Any other ideas would be greatly appreciated.
Welcome to the Zoom Community, @JSlocumb
The most common cause of this is connecting to your company’s network via WiFi. This is especially problematic if several people are connected to Zoom over WiFi at the same location – and more so if they are connected to the same access point. Sure, the packets zip speedily from your access point through the firewall and out to the internet, but there’s competition for WiFi bandwidth with multiple users accessing video – not just Zoom video, but understand that Zoom video has multiple network channels to and from the Zoom servers.
If you are hardwired and having this issue, ask your IT department to do a network trace to determine if there are any other neutral issues that might be causing this.
you might try running zoom network connectivity tool.
please also take a look at your firewall settings.
please also try upgrading to 15.5.5.

Hi @Firescribe your best bet to understand the statistics behind your internet connection with Zoom would be utilizing the Zoom Network Connectivity Tool – Zoom Support mentioned in @Eliot's reply to further see if there is any packet loss, high latency, or jitter with your connection.
I've been having the same problem. A lot of users have this problem, and the problem seems to be with the Zoom app itself. Another user suggested clicking mute/unmute or spacebar when the audio cuts out. I tried this tonight in a meeting and the audio immediately returns, but the same thing happens a few minutes later (like every 4 or 5 minutes). This is extremely frustrating, there doesn't seem to be a way to contact Zoom directly about this problem, and the Community wouldn't allow me to start a new discussion on this topic. The chatbot was very unhelpful. Is anyone at Zoom monitoring this community? Why isn't Zoom addressing this problem?
If you've exhausted all options after considering the following suggestions, could you please let me know if you were the host or if you had problems joining someone else's meeting? The audio problems could have been on their end, and you were the one hearing the audio disruptions.
Connection issues are always so abroad; it's difficult to pinpoint the problem, whether it's you attempting to connect to Zoom servers or our servers attempting to connect back to you.
I am on a wireless network on macOS, updated with the latest Zoom version, with these audio settings and haven't encountered issues with Audio cuts, unless someone lets me know. Also, attached my send/receive audio while in-meeting with another participant. Hope this helps! 🙂
Exactly! I use a paid account to host a meeting with 4-6 people and make one person co-host. During every meeting suddenly everyone else will freeze and I lose their audio. I am at home with 300-400 Mbps continuous download and 15-30 Mbps upload speeds. When the freeze is over I get the same "Your Internet Connection is Unstable" message. During the freeze I always launch the SpeedTest app and check my connection. The Zoom app is the ONLY app on my MacBook Pro (with 32 GB memory) that freezes or stutters or hesitates during viewing video. I will try the tests given above.
