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.
