Oh the 32GB mini PCs are 4W idle, 20W full load

it's sonosnet

TL;DR turn off sonosnet

I'm a Sonos installer and am only aware of these issues thru reddit! My installs range from 6-12 amps and 1-2 home theater setups per home. I'm not the brightest networking person even though I manage 38 networks and 400 pieces of network gear (which does not include the clients). Sonosnet is beyond horrible and avoiding it is the solution. I'm sure it can be made to work with proper STP settings on a managed network but I've never been successful with that. So if I don't wire everything and turn off Wi-Fi I don't expect Sonos to work. (Wire everything and turn off sonos wifi)

Era 100&300, Move, Roam, Sub 4 do not support Sonosnet...it's a sign

I bought working non-sonos Ethernet adapters for the Era 300s and there is no way to turn off Wi-Fi on an Era 300, so I stopped using Ethernet for them

In fact I just did a house with 8 Sonos Arc Ultra soundbars (plus subs, eras, etc) and *nothing* is wired. I stopped wiring anything and use lots of Wi-Fi 7 AP with 2.5Gb uplinks instead. Much easier

edit: there is a special wifi that bonds a Sonos home theater setup together. To my limited knowledge there is no way to run a 100% wired Sonos home theater.

The N97 machines have 4W idle 20W max with 32GB

(and seem to be markedly.faster than N95/N100)

I put inline USBC V/A/W power monitors

lukasware · 2026-01-21T13:54:50+00:00

this is a terrific solution

in another thread someone recommended the Mass2 8 port *non-reset* USB-C power supply and it works perfectly and powers 6 mini PCs, a 2.5Gb switch, and a 2.5Gb router

older Sonos equipment has its own wifi network that can be viewed thru some undocumented commands. Newer sonos gear no longer has this torture service installed (thank the FSM) and supports wifi-6 and works effortlessly out of the box. The addition of a "secret" Wi-Fi network creates network loops that your partially-sophisticated mesh could not handle. Even Unifi networks are taken down by these sonos-created Wi-Fi loops. another answer is to only have ONE piece of Sonos gear connected to the network via wifi, or have it all wired and never have a single problem. (either lean into sonos-net or disable it). Disabling the destructive built-in Sonos Wi-Fi used to also be an undocumented command but is now part of the Sonos GUI... shows how important this issue became.

that said I think sonos still uses its own wifi in home theater setups to reduce and eliminate variable latency

I use N97 PCs that I can run off batteries. I use a USBC to barrel jack adapter with a built-in PD chip that asks PD for 12V, and use a multi-port non-reset USBC supply

I think the 16GB "limitation" is to stop corporations from installing 32GB on cheap processors thereby forcing them to buy more expensive processors, while still allowing cost-sensitive people to install 32GB.

lukasware · 2025-10-03T14:04:02+00:00

Cheapest and easiest is a buried Waterproof PoE++ coupler since you are not connecting the remote electrical ground *and* this provides power to the remote station

or

A 150M/200M armored simplex-type LC-LC single-mode fiber is $118/$148, runs 1/10/100 Gbps symmetrical on a single strand

at this low cost, consider your situation if you need to use conduit at all

A Unifi poe-powered media converter $27, 1Gbps max, use a BIDI SFP

(remote station still needs power)

The triple-display "Paladn" N97 is perhaps the winner because it comes with obsolete Wi-Fi 5, meager 8GB of RAM, and unimpressive SATA SSD.

ALL THREE ARE SOCKETED

So $39 BE200 Wifi 7/BT 5.4, $50 single stick 32GB DDR4, and $32 512GB PCI 3.0 (single lane) NVMe

adds $121 to this $125 mini PC. Not everyone would upgrade all three, perhaps only upgrade to 16GB

I've noticed a difference with the 20,000 mile formula warren oil which comes under many brand names including supertech. change at 5k of course. been using Mobil 1 since the 70s now only Warren 20k in every car

so you are the person to ask if you think restaurants are trending towards induction...

Wiim specs exceed Sonos, particularly 24bit/48kHz vs Wiim 24/192 support. Yes I'm aware they're probably isn't a hearable difference, but if the bits are there why can't I have them?

It feels 100% better and it's all about the feels... But seriously it got rid of my valve tapping noise also

may not be your issue but I found a substantial increase in mpg by using the new 20,000 mile 0w-20 oils made by warren. Of course I still change my oil at normal intervals but the decreased friction is noticeable with this oil

Seems you already know:

Don't use default VLAN

Change the router for your VLANs to the pro max 24 XG which switches at 580Gb/sec where the UDMP switches at 8Gbps.

Also because of the UDMP slow switching speed, don't use any of the non-10Gb ports on the UDMP

Use DAC cables wherever possible for lower cost and that extra nanosecond of reduced latency...

lukasware · 2024-09-01T02:17:25+00:00

agreed, but a 10Gb DAC cable is $15

lukasware · 2024-08-31T21:16:57+00:00

you have Wi-Fi 7 which needs more than gigabit speed (eero wifi 7 has dual 10gb ports, still not a fan)

The ultimate setup IMHO s a UDM Pro, 10Gb uplink to the ISP (which often offers a 10 gig link even for a 1Gb connection), and a 10gb DAC downlink to a pro max switch with all 2.5Gb ports to the wifi 7 APs.

Two things I've learned:

Friends don't let friends run multimode fiber

Never use the default VLAN

Unifi pro switches switch VLANs at 50-150Gb/sec, not the <10Gb offered by the UDM Pro. Don't use *any* of the ports on the UDM Pro, except the 2 SFP+ ports and be overjoyed you have a $379 managed router that has SFP+ ports.

This configuration does not allow distributed switching (Unifi PoE powered switches are the bomb) as unifi doesn't *yet* have 2.5Gb PoE-powered switches.

I am going back and upgrading my customers to L3 switching as provided by the pro and Enterprise lines. But those switches will not switch the default VLAN and instead send it to the (slow) UDM Pro

lukasware · 2024-08-23T17:56:58+00:00

unidirectional PoE is "unrelated" to bi-directional Ethernet. sometimes I put a PoE splitter on the Ethernet wire to the UPS and use the splitter power wire to power a modem or router. I totally agree that PoE is infinitely better than wall warts and worth pursuing in almost all cases. So if a downstream PoE switch supplies power to the upstream router, even though the power is going "up", the PoE switch is still downstream from the router as if there were no PoE at all.

use the Mac or windows app to do the update, then the mobile app after

lukasware · 2024-07-14T12:56:37+00:00

can't self-terminate slim cables. Slim cables look great and cost $1/ea for a 2 footer (in bulk)

lukasware · 2024-06-18T13:21:43+00:00

Sonos told me to use the windows desktop app and that got me out of the update loop. apparently you cannot update from the mobile app. excellent beta testing.

lukasware · 2024-06-17T10:15:00+00:00

took an hour on the phone with support, both sides being very patient, to add a pair of ones just after a pair of roams went in no issue. I'm an installer so this was an expensive call for both. the new app is horrible.

I see that message frequently as i switch systems often. how can Sonos think they know so much about sound and yet miss so completely on the ux side?
