Hi, 

I’ve just upgraded to a newer BT router, after a few hours of messing I’ve finally got everything working again by setting each speaker back up individually. 
My system is on Wi-Fi but I connected a cable to get it all working again with the help of Sonos assistance. 
The cable is now disconnected and everything is set up but the app keeps losing signal and saying unable to connect about 50% of the time? 
It was definitely better before than now? I was hoping a 2 year newer/better router would have been ok? Any suggestions are welcome. 
thanks. 
 

There’s a couple of potentials. First would be some sort of wifi interference, possibly a Sonos device too close to your new router, or one of the other issues presented in that FAQ.

Less likely would be a duplicate IP address issue, what with it being a new router and all, but a simple network refresh could tell, by unplugging all Sonos devices from power, and rebooting the router. Only once the router comes back up should you plug the Sonos devices back in. 

I guess a third possibility would be if you’re using a Sonos BRIDGE, where the power supply is failing, which causes oddities in the signal. If you have one, unplug it from power, and connect one of your speakers to that cable to the router.

I removed the BRIDGE a couple of years ago and it’s been running fine on Wi-Fi, it’s not really possible to have one of my devices wired to the router but I’d  always wondered if I needed a boost to make things better? 
The new router is in exactly the same place as the old one and so are all my speakers. 
 


It’s possible, albeit unlikely, that the new router’s interference radius is different from the old one’s. I doubt a BOOST would help, it is equally susceptible to all the things Hwifi interference, duplicateIP issues)  I mentioned. 


But if you’re interested in getting Sonos involved with hard data, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it, or post the diagnostic number here for a Community Moderator to pick up.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, there are more options available beyond just the diagnostic analysis.

I’ve currently hard wired my connect to the router to see how that performs, not ideal I admit 🤦🏼

I would look at a few things in relation to your new router. Routers often auto-select the best WiFi channel on startup, but that is not always ideal. I would maybe select your own ‘fixed’ WiFi channels, best if they are non-overlapping channels such as 1, 6 or 11. Maybe start with channel 1 for the 2.4ghz band and set a channel-width of 20MHz. Perhaps set the 5ghz band to channel 36 or 48 and opt for a maximum channel-width of 40MHz.

 

If you still encounter issues, then try channel 6 or 11. Give each channel an hour or two before moving onto trying the next one.

 

If all three 2.4ghz channels do not bring about success, then go back to cabling a single device - its best to choose a ‘modern’ (standalone) device, such as a Sonos One for example, which is likely to have a better built-in WiFi card compared to an older Sonos product, but stick to the older product if that suits best for your setup. It’s better though if it’s standalone and not part of a stereo pair etc.


When wiring a Sonos product to the router, try to do that direct, rather than through a network switch and keep the device away from the router itself - the further, the better.

 

The effect of cabling a sonos device, means your entire system will switchover to SonosNet where the devices use their internal wireless connection like a WiFi mesh system. This document explains a little more about that feature:

When running your devices on SonosNet, goto ‘Settings/System/Network’ and set the SonosNet channel so that it is at least 5 channels away from your routers 2.4ghz channel. So if your router is set to channel 1 for example then set the SonosNet channel to either 6 or 11 to prevent interference.

In regards to ‘general’ WiFi interference about your home, you may also find this Sonos support document helpful too:

Thanks for the help 👍🏻

Ive currently got my connect cabled up, it’s the nearest device to the router and since that’s connected it’s been perfect. 
I know it kind of defeats the object getting a newer state of the art set up and then having to hard wire it up?? 
when I go into the BT app it now shows all my Sonos on the main hub with a excellent connection, Before I had some on the main hub and one on the disc and some were good but not all excellent like now. 
I’m definitely just tempted to run this wire neatly and leave it connected?
