Hi,

I have disabled sonoNET on my arc ultra but a wifi scan still shows it is intermittent activity on channel 165 in 5Ghz range

checking status directly on the arc shows HT AP Mode is ON. HT Channel IEEE channel is 165. How can I disable this as this is conflicting with other wifi signlas.

The sonos soundbars use a low latency 5 Ghz wifi to communicate with bonded subs and surrounds. Unrelated to SonosNet toggle (SonosNet is a 2.4 Ghz mesh type wifi setup). If you don’t have sub(s) or surrounds and you want to turn the wifi radio off, connect an ethernet cable, then go into the Arc Ulta settings and select “Disable WiFi”.

Edit: If you do that, it will probably affect your ability to use your Ace headphone audio swap feature.

@audiomtl, FYI, the Arc Ultra is not capable of running SonosNet.
