Lost connection after changing my Network Switch

So I had to replace my network switch as it failed. I have 4 Sonos Connect devices (one Connect Amp and 3 Connects).

Historically I had one connected to the Switch and then the other 3 daisy chained via cat5 cables. All was well.

Now my system “isn’t found” on the network. After trying a bunch of things I decided to hard reset each device (pressing mute/volume up button when powering on until orange light flashes and eventually solid green).

I then reset my app and started from scratch with just one device at a time. However it is still unable to find my device. I can see on my Router that the Connect Amp has an IP address so know it is connected.

But adding a device via the app and going through the “power on” just keeps saying no device found.

Any ideas?

Hardware is as follows:

Modem: Xfinity xb6 in bridge mode (Rogers ISP into this)

Router: Asus RT-AX86U, one port out to the YuanLey uplink port

Switch 1: YuanLey unmanaged 28 Port Gigabit PoE with 2 uplink ports, one of the ports out to the BV-Tech uplink port

Switch 2: BV-Tech unmanaged Switch with 2 uplink ports

Still having other issues with getting both switches to play nice for some reason. Lots of loopbacks depending on how I connect them. Basically right now the only way I can get them to work is to use a crossover cable from an unused port on the YuanLey to the uplink port on the BV-Tech. Which is really odd, wouldn’t think I’d need to use a crossover cable in this day and age.

…and finally, that worked. Had to remove my network switches from the equation and hook the Sonos up directly to the router without any switches connected to the router. Then add each product. Worked.

Then disconnect the Sonos from the router, connected it to a Switch. Then reconnected the Switch. Still works.

Weird. Guess the Sonos products do not like to be setup when first connected via a network switch and not directly to the router?

Yes, a real strange one, especially with an unmanaged switch. I’ve not personally heard, or seen, the issue mentioned before. Anyhow, I guess all’s well that ends well for the start of a new year.

Unmanaged switch.

I’m curious, what is the specific make / model of the switch? There are some unmanaged / ‘smart’ switches that have been know to caused issues with STP.

Links to the switches are in the main post. From Amazon as well below if easier:

Sorry, didn’t see the original links. I’m not familiar with those switches, but the spec on Amazon says first one has a VLAN port isolation mode, where all ports see the uplink (Internet/router) but are isolated from each other, that would definitively impact Sonos network requirements if enabled.
