How to set up NSS333 in Wireless Mode?

Streaming Audio

Out of curiosity I thought I’d try wireless, after all my router/switch/Core is all nearby.

Powered it down, removed the ethernet cable, deleted the naim app and then switched everything back on.

No sign of the NSS333 appearing as an existing device on the app.

Where am I going wrong?

Thanks,

have you tried adding it as a new device?

I did wonder about that. Will that not confuse all my settings and so on?

Thanks,

google AI seems to think you have to add it as a new device, hopefully the app will recognize the serial number and just link it as an existing device

1. Disconnect the Hardware

  • Unplug the Ethernet cable from the back of the NSS 333 network port.

  • Leave the unit powered on, or restart it once after unplugging so the internal system updates its connection state.

2. Run the Wi-Fi Setup in the App

Because the device was previously locked onto a wired connection, you now need to feed it your wireless credentials:

  1. Make sure your smartphone or tablet is connected to your home Wi-Fi network.

  2. Open the Focal & Naim App.

  3. If the NSS 333 disappears from your home screen or shows as offline, tap the **Settings icon (gear icon)**or choose Set up a new device.

  4. Select your NSS 333, follow the prompts to scan for local networks, select your network name, and enter your Wi-Fi password.

3. Quick Alternative: iOS Wi-Fi Sharing

If you use an iPhone or iPad, there is an even faster shortcut once the Ethernet cable is unplugged:

  1. Go to your iOS device’s Settings > Wi-Fi.

  2. Scroll to the bottom under “Set Up New AirPlay Speaker”.

  3. Select your NSS 333. Your iOS device will automatically push your current Wi-Fi network settings and password directly to the streamer.

Many thanks. I did try AI but didn’t pick this up.

Once more unto the breach…

I’m wary of google AI as it tends to make stuff up

I’ll spin up Claude and ask that as it’s more tech focused

Claude says:

You’re right, and this changes the process. Confirmed on Naim’s own support page: Ethernet always takes priority automatically — even if WiFi is configured, the unit will use the wired connection for all network traffic as long as a cable is plugged in.

So the sequence I gave earlier is backwards. What actually needs to happen:

In the Naim app, go to Settings → your NS333 → Network → WiFi and enter your WiFi credentials/select your SSID while still on Ethernet — this saves the WiFi config but won’t actually switch traffic over yet, since Ethernet is still plugged in and takes priority.
Unplug the Ethernet cable from the NS333.
Give it a minute — it should then fall back to the WiFi credentials you already saved and connect wirelessly.
Reopen the Naim app and confirm it reconnects to the streamer and shows a WiFi connection.

Well, I don’t know how it got there, but a combination of setting it up as a new device, getting half way through that before it stalling and me deleting and restarting the app as an existing product.

I’m now wireless.

Thanks a lot.

You shouldn’t have to set up a new device as the app should discover it automatically. Having said that, I’ve had similar issues in the past where the discovery process didn’t work.

When I changed my QB2 from wired to wireless it took about 20 attempts, and after a factory reset I gradually got further through the setup process until I finally reached the end, and it’s been fine ever since.

Glad to know the gremlins of setting up NC has carried over from OC.
