Sonos S1s

iPad Pro OS 18.6.2

iPhone 16 OS 18.6.2

Linksys Velop Mesh network (Nodes: MX5500GC x 2  , WHW03, WHW03CF, WHW01)

I had this multiple times, periodically one device usually iPhone will lose connectivity to the Sonos install. Today I managed to get it to find it by forgetting the network and rejoining it; simple as that! It has been bugging me for months. I use a Linksys Velop mesh network, and Sonos is on the 5gHz separated network (2.4 and 5 gHz have different SSIDs).

 

I guess it could mean that the specific node that Sonos is on was different from the iPhone, maybe the mesh does not broadcast the settings effectively across all nodes???

I have an Asus AiMesh Wi-Fi 7.

  • GT-BE98U Pro (Main node)
  • RT-BE96U x 2 (Satellite nodes)

Main router settings are:

  • Airtime Fairness Off
  • Smart Connect (band steering) Off
  • Same SSID and Password for all bands (No separation) *

Sonos Units

  • 31

Devices

  • iPhone 15 Pro Max
  • iPad Pro
  • Samsung Galaxy Tab A9+ (Android)

 * This IMO is the most critical setting for Sonos. I let Sonos pick the band 2.4Ghz or 5Ghz as do my other Wi-Fi devices. I have no drops or speakers gone missing with Sonos. My network is rock solid.

An important point to remember (not saying you are) is that you cannot compare Sonos to your cell phone or other Wi-Fi devices because unlike Sonos they are “single” points of connection. Sonos is constantly talking across your network connecting across “multiple” points. Therefore it’s (IMO) best to let Sonos choose the band(s) it wants to communicate across. 

Think of 2.4Ghz and 5Ghz as competing ISP’s. In the end they all connect to the same Internet to get you to the Sonos website.


Another point…

If as you suspect that devices (Sonos) connecting to your network via different nodes are invisible to your device that may connecting via another node then your mesh is configured incorrectly. What’s occurring is that your nodes have DHCP capabilities to assign IP addresses which they should not.

BTW… are you still using a router or router/modem combo provided by your ISP? If so the router or router side of the router/modem combo needs to be placed in bridge mode.

As per ​@AjTrek1 comment, don’t use separate SSID/networks for different bands, it is not best practice. Always let the client decide what band to use. As you are using Apple devices, follow the Apple guidelines here:

Network name (SSID)

Set to a single, unique name (case-sensitive) for all bands.

The SSID (service set identifier) is the name that your network uses to advertise its presence to other devices. It’s the name that nearby users see on their device’s list of available Wi-Fi networks.

  • Make sure all routers on your network use the same name for every band they support. If you give your 2.4 GHz, 5 GHz or 6 GHz bands different names, devices may not connect reliably to your network, to all routers on your network or to all available bands of your routers. 

 

Also, you may find WiFi Assist may be causing problems try disabling, if you have a better 4G/5G coverage than WiFi.
