Teams meeting bandwidth issue

[Ming_Law]

If I host a 400-500 teams meeting, is it enough if I use a 500mb Wi-Fi?

Use the Network planner tool: https://docs.microsoft.com/en-us/microsoftteams/network-planner
Or just do the calculations yourself based on the official documentation: https://docs.microsoft.com/en-us/microsoftteams/prepare-network#bandwidth-requirements
