Sonos Era 100 : Unable to find product

Hi, I had the same issue.
It helped to power down the era for about half an hour. The era appear in the app & I could apply the upgrade - after 4 tries of the update it worked.
BR, Mark

I have the same issue ever since purchasing the Era 100. I even got a hold of technical support over the phone; worked for a little bit and as soon as we ended the call, back to hell. I was thinking maybe there’s a network issues so I assigned a new IP address for the Era which worked but after few days of not using the speaker, it wasn’t there to be found. I have to spend 45 to an hour to get it running probably spent dozen times unplugging/replugging both speaker and router. I have multiple Sonos devices and never have problems connecting till this piece of work - Era 100. At this point it should be call - Error 100. I might have to give up at this point and return the speaker. 

Same problem, but I thought “no worries, it has Bluetooth”. But I can’t get that working either and now I see “Era 100 must be set up on a WiFi network before it can be used as a Bluetooth speaker”. I am so sad. Worst part is, I destroyed the box so kinda shot myself in the foot on just returning it. Which I would do right now.

I’m an IT pro, so maybe I’ll get his going. But crap, I don’t want to need to be a pro. I spent good money to get something reliable and that sounds good. But it’s sure not reliable, and I have no idea how it sounds. Maybe I never will :(

Yeah this is a vent. I am so sad.

I didn’t have any device-setup issues at all with our Era 100 speakers. The steps were actually as simple as those outlined in this YT video. 

It really was very simple indeed. I used an old iPhone XR and each speaker was up and running on our Home WiFi within in a few minutes.

I’m happy for you, man. Wish I had the same experience, for sure. I can see my phone and the Sonos on my wireless router, each with their DHCP IP address next to each other in their cozy little subnet. Just won’t talk to each other I guess. I’m able to cast stuff, so I have to think the router is configured OK. Really not sure how much time I want sniffing IP packets or WTF to see how it sounds :(

But I will take some solace in your success. If I figure out a magic bullet I’ll share it.

If it helps you, the Sonos controller uses SSDP to initially discover the players, multicasting via UDP to 239.255.255.250:1900 and, for good measure, broadcasting to 255.255.255.255:1900. 

Thereafter communication is unicast.

So perhaps check your router/AP settings and your controller device aswell, to ensure there isn’t anything preventing the packets getting through.. ensure the controller and speakers are using the same AP and wireless network segment.

You may find that some WiFi ‘mesh’ systems will work better if set to operate in bridged (AP) mode - although some may not allow that configuration (Google Nest WiFi, for example can be problematic and Sky Q networks apparently). See this thread if using a mesh based WiFi system for additional information:

I will just add that the Era 100 speakers do not use a wireless ‘SonosNet’ connection. So if the existing Sonos system is currently running on SonosNet, then check/ensure the WiFi credentials have been added to the Sonos App network settings aswell… see this support link to add a WiFi network (if necessary)…

Thanks for that. I don’t know why UDP would be filtered, but maybe that’s it. It’s not a mesh network, just basic. Asus RT-N66U wireless router with dd-wrt installed on it, but there’s no fancy networking going on. I just went dd-wrt for bandwidth monitoring, it’s all pretty vanilla.

I cleared the cache/data on the Sonos S2 android app and reset the Era 100 by holding the bluetooth button while plugging it in. But, exact same thing. It recognizes the Era fine, it does this thing where it plays a noise the phone listens to to pair (bluetooth? I don’t know), I give it a wireless password and it connects OK (I can see that on the router), but then it spins. After a while I get a screen “Your Era 100 has been added, but may not appear in the System tab. If so, unplug the power cord and plug it bak in to finish setup frm the System tab.” But nothing I’ve tried from here gets the app to find the Sonos.

Maybe I’ll rebuild or replace the router. But more likely I’ll call Sonos tomorrow after work and give them a chance. I’ll do some deep-breathing meditation so I can maintain inner peace while navigating the phone tree or what not. And if they can’t get it done, ask them if I can return it. I pulled the boxes out of recycling, and I bought it directly from Sonos, so hopefully.

I didn’t buy Sonos speakers for a long time because I worried about proprietary software and their wireless stuff. I just wanted a bluetooth speaker. So I kinda feel misled that it’s a bluetooth speaker only if you setup their wireless thing first. But, I’d use the wireless … if it worked for me ;)

EDIT This is my first Sonos device. There’s no legacy setup, it’s all brand new to the hosue

@EdCallahan - deep breath sounds good. maybe sonos provides another update soon.
Unplug the era for a longer time (not just un&replug). That worked for me.
& when the era works - the sound is really great. even in a single setup
