Disable WiFi on multiple speakers

Yes I've noticed the exact same thing. I use to have almost everything wired with Sonosnet and then after last year's update it started not working so well anymore. Audio dropouts ,slow volume control, slow updates in the controllers.... Now after everything is supposedly fixed ,the Ethernet + Sonosnet experience is still not great and definitely not stable. Having everything running off my own WiFi works much better, but since I have access to plug in some speakers to get them off my WiFi that would be ideal to clear up bandwidth for other devices since I still have some older Sonos that only runs on 802.11g.

I'll definitely give them a call to chat, but I've had limited success with support on both chat and phone. I've had discussions with them in the last few months for other issues, and it doesn't seem that they know what Sonosnet is. Most of the time it was getting way to tiring to keep on repeating the same thing so I just told them I'd figure it out myself. I don't think the support they use to have is there anymore. 

While some have success with all speakers wireless connected, I have had many of my speakers wired with WIFI turned on for years with no issues. Even during the past year, my issues have been mor the missing features as apposed to connectivity. But I also never lost access to my local library as some have.

I have wired my main speakers as well and my oldest speaker, a Play 1 to my network:

Arc -  wired with Sub and surrounds wireless connected. Arc’s WIFI has to remain on for this.

Play 1 - hardwired

Five - hardwired

Amp - hardwired

Connect S15 - wireless Sonosnet. 

Play 5 Gen 2 -  wireless Sonosnet

I just have a single AP in my home, so separating channels for WIFI and Sonosnet is easy. My other AP is in my garage and is far away enough that it does not interfere with Sonosnet, but it is on a non overlapping channel as well.

The other thing I have done was assign static IPs to all my speakers a long time ago.

I've asked Sonos to add an option to the older Sonosnet speakers that is the default on the Eras, allow us to connect Ethernet but not enable Sonosnet.

That for me would be an ideal setup, wire ones I want but not mess up the ones working so well on my Wi-Fi. 

​@Stanley_4, If you don't want SonosNet, disable the WiFi module on the older speakers. That’s exactly what’s happening when an ethernet cable is plugged into the Era 100/300 or the Arc Ultra but automatically.

Disabling wifi on older Sonos also disables the 5 gHz signal used for Sub and Surrounds so all the theater set devices would have to be wired. Not what I want, I want only Sonosnet disabled so all my other Sonos stay connected to wifi.

Maybe I'm confused then, I thought there was no support for Sonosnet, under any circumstances on the latest Sonos.

Let me give you a couple examples.

I have an Arc, Sub 2 and 2 Play ones. I want to wire the Arc but not enable Sonosnet as that pulls my nearby Play 5 off my wifi. I do not have the ability to wire the Sub or Surrounds so disabling the wifi also disables them.

Similar room with a gen 1 Beam Sub 2 and 2 Ones.

Another room with an Arc Ultra, Sub 4 and 2 100s. I replaced the Arc with it and never considered hooking the Ethernet back up, I may look into that as having it wired but not doing Sonosnet would be good as long as the unwirable Sub and Surrounds would still work.

I do have a single One that I could wire and disable wifi so I understand how that works.

I don't have or want my 100 or 300 Sonos wired, don't even own the required modules, so I haven't looked at the wired options or configuration there.

SonosNet also requires an ethernet port built into the Sonos gear, meaning the Arc Ultra is (sort of) “SonosNet-ready”, so is the Era 100 Pro. Era 100 and 300 would have to be retrofitted for SonosNet v3 (still hoping 🤗).

Edit: It is a misconception that the Arc Ultra can be the solely wired device in a surround setup.

You can get an ethernet port for Era 100/300 now.

The adapter may not suffice. A hypothetical SonosNet v3 may require an overhauled hardware to fit the firmware.

Unless I am not understanding this or it is wrong, Sonosnet is not an option for the Era, Ultra or Sub 4 under any configuration.

Products that don’t support the dedicated Sonos wireless network

The following products must either be connected to your home WiFi network in a wireless setup or connected via Ethernet, if supported.

Arc Ultra

Era 100

Era 100 Pro

Era 300

Move

Move 2

Roam

Roam 2

Roam SL

Sub 4

Here is another example:

Limitations when using Era 100 or Era 300 as surrounds

 

When Era 100 or Era 300 speakers are used as surround speakers, there are some limitations to their Ethernet connectivity when using the Sonos Combo Adapter.

When the primary home theater speaker is connected to the network with a wireless connection, the Era surround speakers cannot be connected to the network with an Ethernet cable. However, if the home theater speaker is wired to the network, then the Era surround speakers can also use Ethernet connections if desired.

Correct, due to hardware limitations (missing ethernet port).

Tom Conrad was sympathetic to this request in his AMA on Reddit. Anyhoo, I don't believe that it will be realized, since the SonosNet is already on its way out.

Missing Ethernet port? Sure looks like the Ultra and Sub 4 have internal ones and the Eras support external ones.
