How to set-up an optimized WiFi network to stream

Streaming uncompressed audio data over WiFi requires a solid, high-quality network. This is key to insure a coherent and lossless data transmission to a Devialet. The routers supplied by internet providers are usually too weak or unadapted. They are fine to do mails or surf the internet, but can hardly cope with a significant data-flow involved in an HD audio-stream. Additionally, streaming requires a strong WiFi signal at a Devialet. We advise to reach for any value higher than -55dBm - ideally -45dBm or better if possible.

As a user, it is your task to set-up a porper WiFi network to stream to a Devialet. ( as well as a proper wired connection)

In order to stream, you need to download the Devialet AIR application corresponding to your computer from our website at:, ... configure the Devialet AIR input to lock onto the appropriate WiFi network using our online configuration tool.



In a first instance, you may try to connect your Devialet to your current router and test the stability. All you need to do is to configure the Devialet AIR input to lock onto your network using the online configuration tool (enter your network's name and password). Don't use any special characters such as: %, *, # etc.... Only plain alphanumerical characters.

If it works, brilliant! You can enjoy hours of music streamed to your Devialet.



If, despite an obvious connection to the network, there is no transmission possible or if you hear noise and crackles added to the audio signal or if the transmission is impossible above a certain sample rate, we strongly advise you to build your WiFi network around Apple products. Those devices are not expensive and they simply work!

A simple and very efficient solution is to use a dedicated network for the audio data built around a simple Apple AirPort Express disconnected or not from the internet. Please keep in mind to place the AirPort Express as close as possible to the Devialet and the PC. Ideally, the three elements should be in the same room and only a few meters away from each other.

The first thing you will need to check is your network condition:

On a Mac, using istumbler you can monitor your Wi-Fi network (signal strength, noise level, channel used).

On a Windows PC, inSSIDer can monitor your Wi-Fi network ( signal strength, noise level, channel used ).

On an Android phone, WiFi Analyzer can monitor your Wi-Fi network ( signal strength, noise level, channel used ).

To identify the best channel for your own Wi-Fi network, take a look at the other Wi-Fi networks around you, as listed in the stumbler application. Identify the channel from 1 to 12 that is the least used. Do not use channel 13 as it is not supported by your Devialet. You can choose the channel in the AirPort Utility application.

The AirPort Utility application lets you do the set-up. Note that this application, standard on a Mac, is also available for PC ( and as an iPhone/iPad app (AirPort Utility)

Select the new AirPort Express in the list and follow the steps on the AirPort Utility application.



Click on your AirPort Express to modify 2.4GHz Channel of your wifi network. Also you can create 2 network, one on 2.4Ghz, one on 5Ghz. Then you can use only the 2.4Ghz for your Devialet and 5Ghz for your computer and other devices.

At last don't forget to configure your Devialet to lock onto this newly created network.


If you don’t want to create an Audio dedicated network or if you need a stronger network to cover your home needs, we recommend you to build your network around the more powerful AirPort Extreme.

You simply need to connect the AirPort Extreme to your router with an Ethernet cable, disable the WiFi on the router and configure the AirPort Extreme, as explained above, to create a WiFi network. This network will be the one you will use to stream and access the internet at home.

If the AirPort Extreme is located too far away from the Devialet, you can still add one or two AirPort Express in bridge mode, connected via Ethernet to the router, and placed next to the Devialet and to the PC dealing with players. This will ensure a steady data flow.

Lastly, if you don't want to have an Ethernet cable running between the AirPort devices, you can set-up the AirPort Express as WiFi network extenders. Note that in this case the available bandwidth is shrunk.

When you're done with your Devialet configuration, write the configuration file on your SD-Card. Eject the card and insert it in the Devialet. Power the Devialet and select the AIR input. If the Devialet is locked onto your network, you should read AIR written in Grey and have at least 3 WiFi level accolades visible.


All you need to do then is open iTunes on Mac and any bit perfect player on PC, open Devialet AIR, make sure your Devialet is ticked off (visible when you click on the Devialet AIR icon) and start streaming.

To stream from your iPhone/iPad, simply download the Devialet app from the iTunes app-store. Then open the app, tip on the source, select My Music, select the song(s) you want to play, press "Done" and the music will start.

The illustrated pulldown of AIR SETTINGS does not match what appears in Configurator. Also, it is not possible, contrary to what is shown in the example on this page, to check both DHCP and ADHOC mode as ON.

In general, the information on this page lacks the precision of instruction necessary for the average user to follow. So much vague, unclear instruction all over this site, Devialet.

I see you've now changed the pulldown to match the current Configurator. But I still don't understand why you show both DHCP and ADHOC highlighted. To check the one cancels the other in the software.

Are you aware that Apple has a new AirPort Extreme 802.11ac model?

No reply from Devialet for a long long time. Kind of sad, guys.

I have updated my wifi network and included the new Airport Extreme 802.11ac placed directly next to my two d-premier operated in dual-mono setup. Airport Extreme is connected via Ethernet to a former Airport Extreme 802.11 b/g/n which is connected to my mac mini. Wifi signals are in the range of -26 to -39db. Devialet Air 2.0 works with files up to 96/24 but ALWAYS crashes with 192/24 files. It seems that Devialet released Air 2.0 without appropriate testing. Very disappointing. It makes me questioning to upgrade to the new 240 if that should be Devialet's new approach to product quality and lack of responsiveness on clients' comments as demonstrated on the website.

Maybe early hibernation? Unbelievable :-( No show since weeks again. And this theme is one of the so called 'Hot topics' - Lol.
