# NavVis IVION: Minimum Browser and Network Requirements

This article lists the minimum browser and network requirements for a smooth NavVis IVION experience. If you experience slow or laggy performance, start here before contacting Support.

## Supported browsers

NavVis IVION requires an up-to-date, modern web browser. The following browsers are supported:

- Google Chrome
- Microsoft Edge
- Apple Safari
- Mozilla Firefox

> **Note:** Internet Explorer is not supported.

Keep your browser updated to the latest version to benefit from performance improvements and security patches. For instructions, see [How to update your browser](https://www.whatismybrowser.com/guides/how-to-update-your-browser/).

## Browser extensions and plugins

Browser extensions and plugins can interfere with NavVis IVION performance. If you experience unexpected behavior, open your NavVis IVION instance in a private (incognito) tab to rule out extension conflicts.

## Network requirements

NavVis IVION requires a fast and stable internet connection. The following factors can affect performance:

- **Connection speed:** A slow internet connection or high latency causes delays when loading data. This is especially noticeable on slower connections or in areas with poor network infrastructure.
- **Network stability:** Packet loss and network congestion reduce data transfer speeds between your device and the NavVis IVION server.
- **Server distance:** The physical distance between your location and the web server affects load times.

## Verify your connection

To confirm that your network meets the requirements:

1. Test your upload and download speeds at [fast.com](http://fast.com).
2. If speeds are low, switch to a different network (for example, a mobile hotspot or a private network) and retest.

## VPN and firewall considerations

VPN connections and strict firewall settings can degrade NavVis IVION performance. If you suspect either is causing issues, temporarily disable the VPN or switch to a network without strict firewall rules to test.

For detailed troubleshooting steps, see [Troubleshooting slow speeds with your NavVis IVION instance](https://knowledge.navvis.com/docs/troubleshooting-slow-speeds-with-your-navvis-ivion-instance).

## Contact Support

**Still experiencing issues?** If performance problems persist after verifying your browser and network setup, contact NavVis Customer Support at [support@navvis.com](mailto:support@navvis.com).
