Why won't my Nintendo Switch work on the guest network?

The short answer

Local play with another Switch fails on guest networks. 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

• • Run the console's own internet connection test from the dock's usual spot.
• • Use a USB network adapter in the dock for downloads — cheap and transformative.
• • Move the dock out from behind the TV.
• • 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 wired USB adapter first; mesh only if other devices in that room also struggle.
