After five months, we can finally say that the Quest 3 is a very good wireless PCVR headset for any Wi-Fi 6 router. The TP-Link AXE5400 (AXE75) works smoothly now, but there are still some kinks to work out.

Have problems finding and connecting to your 6G?:
Figuring out why the 6GHz network isn't showing up can be a bit tricky, especially since it seems to be affecting only a handful of TP-link AXE users. Here's a roundup of what people have shared to help troubleshoot:

- Ensure your router is running the latest firmware through the Theder APP.
- Run a network diagnosis to rule out any channel conflicts: Theder APP - Tools ➡ Network Diagnostics ➡ Diagnose.
- Confirm that the 6GHz network has a unique name and passkey. (preferably 8+ characters with only numbers, letters and underscore)
- In the Theder app, access advanced settings for the 6GHz WiFi and activate PSC. Ensure "Hide SSID" is not toggled.
- Be patient! Give it 3 to 5 minutes on the WiFi settings page on your quest and see if the 6GHz magickly appears.
- Add the network manually. Write down the Name, Security protocol, and passkey (e.g., TP-link-VR6G, WPA3-Personal, passw0rd23), then manually add the network on your quest without scanning.

Additional Experiments:
- If 2.4GHz and 5GHz are disabled, try turning them back on and se if the 6GHz network also appears.
- If Smart Connect is disabled, try enabling it to see if it resolves the issue.
- If OneMesh is activated, consider deactivating it as an experiment.

Connecting to 6GHz Network but disconnects randomly:
- If you manage to find the 6GHz network but experience disconnections:
- Head to the Wi-Fi connection settings on your headset. Under privacy, choose "Use device MAC."
In the TP-link web client you can try giving it a fixed IP using Network ➡ DHCP Server ➡ Address Reservation.
