{% hint style="warning" %} If you still have no luck, it may even be worth temporarily disabling Mobile Data on your smartphone to be sure. And in the event that it is something more problematic, like the 2.4Ghz band on your network has been disabled, you will have to consult your modem/router's guide or internet provider to resolve it. {% endhint %} *** ### App - Zen Link™ V2 Not Found If you have previously setup the Zen Link™ V2 and the app is *not* connecting to it, make sure your smartphone is connected to the **SAME** network and **PRESS** the "**Retry**" button. * Make sure your Zen Link™ is powered on and reachable via Wi-Fi or Bluetooth® . * Make sure your network is still allowing for 2.4Ghz connections, because the Zen Link™ is a 2.4Ghz device.

*** ### App - Wi-Fi Configuration Retry In the event that your Zen Link™ V2 *cannot* connect to Wi-Fi, it will return to Setup Mode (solid **BLUE** LED), and the app will automatically detect that Wi-Fi needs to be configured again.

*** ### No Headset Audio on PS5® A 3.5mm wired headset is *unsupported* when your DualSense™ is paired wirelessly to the Cronus Zen™ via Bluetooth® . It will work if your controller is wired to one of the Cronus Zen's front ports (A2 or A3). If you'd prefer to use your controller wirelessly with headset audio, you'll need a USB or wireless headset that connects directly to your PS5® console. *** ### No Connection to PS5® The PS5® console setting "**Communication Method → Use USB Cable**" is especially important for the PS5® to be able to connect through the Cronus Zen™ and Zen Link™ V2 at all. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://guide.cronuszen.com/zen-link/troubleshooting.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
