Era100 stereopairing with sub

Can you describe your network to give a better idea of  things that may be causing connection issues?

Do you have any extenders, powerlines or VPNs within your network?

Have you rebooted your network?

Any additional information you can provide will help diagnose the cause of your issue.

Troubleshooting is good but I’m a fan of taking a bit of preemptive action in cases like yours.

Go to your router’s DHCP settings page and assign ALL speakers a static/reserved IP address, the router’s page should have instructions.

Power down ALL Sonos. Reboot the router. Power up your Sonos 100s.

If you don’t mind redoing the install I’d Factory Reset all three just to get a clean start on things. Then go through the initial setup on one of the 100s, add the second to your system and pair them. Now power up the Sub and add it to your 100’s Room.

If that doesn’t get you working you have at least removed one possible failure mode from the list of possibilities for very little effort.

Thanks guys for your replies. I dont know much about networks but I have no extenders or vpn. Wireless 5ghz. I get about 70 Mbit/s in the position of the Sonos system.

WPA2 PSK security and 802.11a/n/ac standard.

Dont know if this tells you much. Been running airplay for a couple of years without issues.

Will restart the sonos units again.

Cheers!

Hi guys,

so all units where reset. Router rebooted. Last night i setup one Era100. There was a new update. Ran trueplay, everything worked fine.

Today i started up the second Era100. New update, ran trueplay. Was asked to setup a stereo pair. True play again. And both played fine.

So time for the sub. New update, add to the system. Back to square one. Only sound from one Era100. No progress.

I separated the stereopair. I can toggle between the rooms. But they wont play together. And no sound from the sub.

Will reset all units again and this time add the sub before the second Era100. I have tried this before and thats the only time the sub has worked. Untill i add the second Era100.

Fingers crossed

So I restarted one Era100. Ran trueplay. Played fine.  Restarted and added the sub. Worked fine.

Restarted the second Era100. Ran trueplay. Added as stereo pair. Sub goes dead. But stere pair working.

Removed the sub from the room. All works fine. Added back the sub to the room. Only sound from one Era100. And trueplay fails.

Sorry guys I dont think this combo works. From what i have heard the sound is not very impressive either.

Will return the system.

Cheers

OK….try this…

Since you have nothing to lose as you say you’ve already spent an hour with Tech support…Factory reset all your speakers and follow the process below in the order written…

1. All products should be flashing green
2. Go to app and select add a product 
3. Add a Era 100 and create a room
4. Go to app and select add a product
5. Add the second Era 100 and create a room with a different name 
6. Go to a room with either Era 100 and select create stereo pair ( you can change the room name afterwards)
7. Go to app and select add a product
8. Add the sub to your system ( do not try to add it to the stereo pair at this time)
9. After the sub is added to your system you may be asked if you would like to add it to a room. If so select the room with the stereo pair 
10. If you are not prompted to add the sub to a room just go to the room with the stereo pair and select add a sub.

Let us know if you’re successful to get things working as you like.

Edit: Sound being impressive or not is a personal matter to the listener. Don’t let someone else decide what sounds good to your ears.

Are you playing via airplay or from Sonos app?  I have the exact same setup as you. Works fine from Sonos app, but airplay is flakey as hell, with either both or just one era playing. Seems to work best when connected to 5ghz channel, but no way to force this, at least not with my router. Good luck. 

AjTrek1 I followed your steps and when I try to add the sub it fails. I get a message to check the network connection or that the sub is plugged to the power outlet.

Restarted the sub with the same result.

I did reposition the system before trying your suggestion.

The sub adds fine to the network so I dont know whats wrong.

I am only using Spotify through Sonos app at this point.

All devices connected via wi-fi, or any via Ethernet?

All wi-fi.

 How is the SNR ( Signal To Noise Ratio ) when both 100s are connected to WiFi?  Settings - Manage - 100 Room name - 100 - Network.  Look for SNR.  Do thes for both

SNR is 38 and 25 on the Eras.

That 25 is pretty low.  Sonos recommends 45 or higher.

​@AjTrek1 is right about the 2.4 band having better wall penetration if that’s your issue.

Victory!

Changed to the 2.4 GHz band and everything worked perfect. Big thanks guys!

First i had the Eras on a shelf in my living room. Sound not that great. Moved them to the window ledge and the sub in a corner. Big improvement. Room filling and easy on the ear.

cheers
