Hi CDtooti,
Thanks for reaching out to Apple Support Communities. It sounds like you're having an issue with a third-party app on your MacBook Air. We're happy to assist.
If this is the only app that has a connectivity issue, we'd recommend ensuring the app developers directions for checking permissions and installing were met. Their guide here can assist: Installing the Zoom application on macOS
You can also ensure your router are set to the recommendations found here: Recommended settings for Wi-Fi routers and access points
If the issue is with multiple apps and services, check out the steps here: Solve internet connection problems on Mac
You can also test connecting in a new user account and in safe mode:
Start up your Mac in safe mode
Set up users, guests, and groups on Mac
If the issue doesn't occur in a new user account, check your current login items and test using the steps here: Remove login items to resolve startup problems on your Mac
You should also double-check the firewall settings and reinstall the app if the issue continues. Block connections to your Mac with a firewall
Best!
