Why won't my Meta Quest 3 work on the guest network?

The short answer

PC streaming won't work across a guest network. Guest networks deliberately stop devices from seeing each other. That is exactly what this gadget needs to do, so it fails — as designed.

What's happening underneath

Online play often fails on guest networks.

Try these, in this order

• • Use the 5 GHz or 6 GHz network only — hide or avoid the 2.4 GHz name while playing.
• • Keep the router or mesh box in the same room, in line of sight.
• • Plug the PC into the router with a cable so only one link is wireless.
• • Check the signal where the gadget actually lives, not where you're standing.
• • Move the router off the floor and out of any cupboard before buying anything.
• • Put the gadget and your phone on the same Wi-Fi name.
• • Restart the gadget before the router — it is quicker and it fixes more.

Setting it up again properly

• • Stand next to your router while you set it up, then move the gadget to where it lives.
• • Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
• • If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
• • Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.

When it's worth spending money

A dedicated access point in the play room is worth it here — this is one of the few cases where it genuinely is.
