Follow these steps for Allowlisting the HTC VIVE Focus 3 to an enterprise network 1. Locate/record the device’s MAC address (Settings \> General \> About \> Headset Status). If the MAC address says “Unavailable” or seems to have changed after a device update, you will need to identify the MAC address under the WiFi network that the headset is connected to. 2. If the headset is logged into a network already, forget the current WiFi network that the headset is experiencing connectivity issues on. To forget the network, select the network and click on the button that says “Forget”. 3. Identify the desired WiFi network and **BEFORE** you confirm the connection, configure the headset's MAC address via the "Advanced Options" menu. 4. This can be found by navigating to Connectivity -\> WiFi 2.4/5/6 Ghz -\> Click on your WiFi network -\> At the bottom of the screen click on "Advanced Options". Scroll down the page and expand the privacy drop down menu where you will find the MAC address options. Select "Use Device MAC" address instead of the default "Randomized MAC address".  Proceed to join the desired network once this change has been made. 5. Now the "Used Device MAC" address is the "native" device Mac address 6. Add the device's static MAC address in the applicable firewall admin (Trusted Device) page 7. Verify the device is now connected via Wi-Fi. - [READ ME - Using the PeriopSim Knowledge Base](https://support.periopsim.com/read-me-using-the-periopsim-knowledge-base?hsLang=en) - [General Questions?](https://support.periopsim.com/general-questions?hsLang=en#main-content) - [Free Trial Account](https://support.periopsim.com/general-questions?hsLang=en#free-trial-account) - [How do I ... ?](https://support.periopsim.com/general-questions?hsLang=en#how-do-i) - [How do I use the product?](https://support.periopsim.com/general-questions?hsLang=en#how-do-i-use-the-product) - [Contact Us](https://support.periopsim.com/general-questions?hsLang=en#contact-us) - [PeriopSim Learning App](https://support.periopsim.com/periopsim-learning-app?hsLang=en#main-content) - [Getting Started | Frequently Asked Questions](https://support.periopsim.com/periopsim-learning-app?hsLang=en#getting-started-frequently-asked-questions) - [How do I... ?](https://support.periopsim.com/periopsim-learning-app?hsLang=en#how-do-i) - [Educator Portal](https://support.periopsim.com/educator-portal?hsLang=en#main-content) - [Dashboard](https://support.periopsim.com/educator-portal?hsLang=en#dashboard) - [Learner Portal](https://support.periopsim.com/learner-portal?hsLang=en#main-content) - [Getting Started | Frequently Asked Questions](https://support.periopsim.com/learner-portal?hsLang=en#getting-started-frequently-asked-questions) - [PeriopSim VR for HTC VIVE Focus Series](https://support.periopsim.com/periopsim-vr-for-htc-vive-focus-series?hsLang=en#main-content) - [Getting Started](https://support.periopsim.com/periopsim-vr-for-htc-vive-focus-series?hsLang=en#getting-started) - [VR Setup for HTC VIVE Focus Series Headsets](https://support.periopsim.com/periopsim-vr-for-htc-vive-focus-series?hsLang=en#vr-setup-for-htc-vive-focus-series-headsets) - [Frequently Asked Questions](https://support.periopsim.com/periopsim-vr-for-htc-vive-focus-series?hsLang=en#frequently-asked-questions) - [PeriopSim VR for Meta Quest](https://support.periopsim.com/periopsim-vr-for-meta-quest?hsLang=en#main-content) - [VR Setup for Meta Quest Series Headsets](https://support.periopsim.com/periopsim-vr-for-meta-quest?hsLang=en#vr-setup-for-meta-quest-series-headsets) - [PeriopSim for PC Based VR](https://support.periopsim.com/periopsim-for-pc-based-vr?hsLang=en#main-content) - [VR Setup](https://support.periopsim.com/periopsim-for-pc-based-vr?hsLang=en#vr-setup) - [PeriopSim for Windows PC](https://support.periopsim.com/periopsim-for-windows-pc?hsLang=en) - [PeriopSim for macOS](https://support.periopsim.com/periopsim-for-macos?hsLang=en#main-content) - [macOS Setup](https://support.periopsim.com/periopsim-for-macos?hsLang=en#macos-setup) - [PeriopSim Traveling VR Demo Kit](https://support.periopsim.com/periopsim-traveling-vr-demo-kit?hsLang=en#main-content) - [Getting Started](https://support.periopsim.com/periopsim-traveling-vr-demo-kit?hsLang=en#getting-started) - [Frequently Asked Questions](https://support.periopsim.com/periopsim-traveling-vr-demo-kit?hsLang=en#frequently-asked-questions) - [PeriopSim for iPad](https://support.periopsim.com/periopsim-for-ipad?hsLang=en#main-content) - [iPad Setup](https://support.periopsim.com/periopsim-for-ipad?hsLang=en#ipad-setup) - [PeriopSim for Android Tablets](https://support.periopsim.com/periopsim-for-android-tablets?hsLang=en) - [PeriopSim from Google Play Store](https://support.periopsim.com/periopsim-from-google-play-store?hsLang=en) [![periopsim-icon-wordmark-3](https://support.periopsim.com/hs-fs/hubfs/periopsim-icon-wordmark-3.png?width=202&height=50&name=periopsim-icon-wordmark-3.png "periopsim-icon-wordmark-3")](https://support.periopsim.com?hsLang=en) PeriopSim Help Center Copyright © 2026, Conquer Experience Inc.
