RBS50 - Adding one more Sonos Play1 drops internet connectivity after awhile

Question

Using Firmware v2.1.1.16 with the RBR/RBS50. Connectivity is all working, have multiple switches downstream of the RBR, with multiple devices either plugged in via ethernet or connected wireless. Currently 18-19 devices are all connected either wirelessly or wired. Devices range from QNAP nas, computers & laptops, home theater system, various Sonos devices, iphones/samsungs, tablets, etc.

Issue comes with adding another Sonos Play:1. I already have an old 90, 120, 2 Play:1's, and a Play:3 all in different rooms, all wired directly into switches. If I add the last Play:1 via hardwire cable, again in another room, then by the next morning, my internet is down and I need to unplug the last Play:1, and reboot the Orbi. Wireless still works, but does not provide access to the internet.

I've checked to make sure I do not have an ip address conflict, using DCHP so wouldn't think I would, and WAN/LAN range has more than enough free IP addresses to assign, but not sure of what else to check??? I do see some Dos Attack: ACK Scan in the log, but that's with the Play:1 not connected.

[DoS Attack: ACK Scan] from source: 69.16.175.10, port 80, Friday, January 12, 2018 18:46:30

Any help would be greatly appreciated.

Yes, it is very confusing. &nbsp;It's a little difficult to understand,&nbsp;but it's necessary to&nbsp;understand how Sonos works in order to avoid problems.
&nbsp;
You need to choose whether your Sonos system will operate on WiFi or Sonosnet, and this is done as I described in my first post.
&nbsp;
To use WiFi with Sonos you must never plug in ANY Sonos device. &nbsp;This is because as soon as you wire the first Sonos device, the entire system will switch from using WiFI to using Sonosnet. &nbsp;From what you have written, it appears you think you are using WiFi on some Sonos devices, but you are actually using Sonosnet on all of them if you have any plugged into Ethernet.
&nbsp;
If you use Sonosnet, then you must manually manage channels on Sonos and Orbi, as I described. &nbsp;You must also ensure you have your Sonos devices distributed around the house such that they can form their own independent mesh network. This isn't difficult, because they have good range. &nbsp;Your WiFi plays no role in Sonosnet, other than as a potential interference source. If you use Sonosnet, then you should avoid plugging in more than ONE Sonos device. &nbsp;If you plug in more than one Sonos device you can create a network loop that will crash your network. As you have discovered, this can be a bit unpredictable, due to the dynamic routing that Sonosnet uses.
&nbsp;
You don't need a bridge or boost to use Sonosnet--every Sonos device includes the necessary hardware. &nbsp;If you have a bridge or a boost then you can place them around the house to help fill gaps in the Sonosnet mesh.
&nbsp;
I use Sonosnet and it works perfectly&nbsp;with Orbi in my 3,000 SF three-level house. &nbsp;I have two bridges and seven Sonos speakers. I have one componenet wired to Ethernet--a Playbar.

Do one of the following.&nbsp;
1) Disconnect all Sonos from wired ports and set Sonos to use your WiFi, or
2) Disconnect all Sonos and wire only ONE Sonos device to Ethernet, and manually set Sonos&nbsp;to use Channel 1 and set Orbi to use Channel 11 in 2.4 GHz, or vice versa.

I have found Sonos to be very sensitive to ip conflicts so to avoid issues, ensure you start with all Sonos items powered off and then restart your router. You should then add your wired Sonos item an then power up the rest.

as said above, it is very unwise to have more than 1 wired Sonos item to avoid loops.

Thanks for the additional detail, much appreciated.&nbsp; Two clarifications though for my system...&nbsp;&nbsp;First, I have 1 Play:Amp (old zp90), 1 Play:Connect (old zp120), a Play:5, and three Play:1's.&nbsp; Wasn't sure if the Play:Amp and Play:Connect had the wifi hardware to support, always thought I needed a Bridge device, which I never got because those original two were always hard-wired by ethernet to my network.&nbsp;Second, all my Sonos components were hard-wired, or I was attempting to use ethernet cables for all of them.&nbsp; I had 5 of them all plugged in via ethernet cable to the network, no issues with any of them.&nbsp; I was then attempting to add the last Play:1 to the network via ethernet cable, and that's when it seems to shut down my internet connection.&nbsp; None of the components were set up in a wifi configuration I thought.&nbsp; Have enough devices with kids and other crap sucking wifi, figured hard-wiring via ethernet I wouldn't have to worry about dropped signal or bandwidth.&nbsp;But I'm now playing around with what you have suggested... Have the Play:Amp connected, and will attempt to use wifi for the others in that configuration.&nbsp;And one more caveat... I hope I'm not chasing my shadow here and it's not the kid's xbox one upstairs... again hard-wired via ethernet and have put a static route in for that in Orbi.&nbsp; Don't think there's anything&nbsp; else up there in that room.&nbsp;Appreciate all the help and feedback!
