Sonos affected by Wireless Access Point hardware change

Seems like they removed that possibility in the v3 hardware, in v2 it was part of the settings:

See section 3.4

Also found some people that actually had DHCP trouble on their forum: https://community.tp-link.com/en/home/forum/topic/192368

Ah yes, I have a couple of RE2xx devices -- not in use -- and that rings a bell. 

Interesting…

I have found a workaround of sorts. I have moved the RE 205 to replace another AEX access point in my son’s room, where there is no Sonos, and moved that AEX to my bedroom where there is Sonos and Firestick/Macbook. 

All is now working fine in both rooms. 

A question: if I need to replace this AEX in future, what are recommended replacements that will be a drop in such that Sonos will not be affected? All I need is a AP that can be fed by the second port of a connected to main network via wire Sonos unit, such that WiFi signals in the room are 5 GHz and stable/fast.

That is what the AEX is doing, set up in access point mode.

I’ve had mixed results with the TP-Link RE2xx units (which is why they’re out of use). 

There have been no issues using the older (single-band) TP-Link WA850RE, or a small ASUS RP-AC52, hung off a wireless Sonos unit. In both cases I disabled the back-up DHCP server.

Thanks gents, for all the inputs.

A question for access points in general. If one was to buy an access point that works only as that when wired back to the router - assuming that such devices exist - can one assume that if it is added to the core network via a wire from a Sonos unit wired to said network, it can be assumed safely that it will work without any hiccups in Sonos?

Keep in mind that the SONOS network ports are 10/100. 

@buzz yes, but that has not been a constraint in the six months that I am using them to extend wired internet within a room. I consistently get speeds of 50 Mbps broadband per my plan from the access point so wired, just the way I get these speeds from the main router. Firestick HD Video streams are solid and there is no effect on Sonos music play. I suspect the missing gigabit port feature is one that is rarely needed in domestic environments in practice.

The problem with Sonos raised its head only when I replaced the Airport Express with the TP Link as the wired from Sonos Port WiFi propagator in a remote bedroom.

PS: Note that Sonos net is not in use here, the Sonos unit is being used just as simple switch where the access point is concerned. 

The Connect Amp dropped off again, and I suspect this happened after the TP Link on the other side of the wall was powered on by my son on his arrival. 

Very frustrating. The system as is consists of the Boost and few other units including the same Connect Amp wired to the core network. The TP link just has the one wire running back to the router anchoring the core network, no connection to any Sonos unit except via being connected to the same router/switch. To avoid WiFi interference from the TP Link, I have even disabled WiFi on the Connect Amp. 

As soon as it was rebooted, the Connect Amp came up again, and perhaps it will now stay that way until the next time the TP Link is power cycled!

A possible clue?

I find that invoking the matrix takes time ranging from less than a second at times to over a minute at other times; sometimes it takes a second click to get it to start the process. 

This, from the same device/location, in the bedroom, with the Mac host signed on to the AEX access point.

When there is a delay, often the information about the Sonos units does not show up in the Sonos controller, under the about my system.

Is this related to the topic issue?

Does the AP also broadcast a 2.4GHz signal too?  I have a TP-Link Re650 that broadcasts both 2.4 & 5GHz (although it doesn't give me any issues) - but allows the channel to be selected. (sorry if already covered, I only speed read above).
