Sonos Era 100 Not Registered – Quick & Easy Solutions!

Tip: Follow the steps chronologically!

1. Use the Same Email Address

The first and most important step when Sonos Era 100 cannot be registered is to make sure that you’re using the same email address.

This applies especially when you already have a Sonos system set up with other speakers, and you’re trying to add a new one to the system.

So, when you select “Join existing system” verify that you’re inserting the same email address that you’ve used to set up your other Sonos speakers.

If you don’t have an existing Sonos system and this is your first Era 100 speaker, but it cannot be registered, on the “Welcome” screen, input your email.

Then, head to your inbox and follow the instructions from the email that you should shortly receive.

If you’ve been through all of this, but the speaker appears as “Not registered” keep reading!

2. Restart Mobile & Wi-Fi Router

The next step is quick, but efficient, especially when a Sonos Era 100 speaker appears as “Not Registered” in the Sonos app.

This may be a bug/glitch, so we strongly recommend rebooting your Wi-Fi router and mobile phone, to refresh the connection between both devices and test.

So, power off your router or modem and disconnect the cord for 60 seconds. In the meantime, hold the power button on your mobile to “Shutdown” and refresh the system.

When you power on your Wi-Fi router, leave it for 3 minutes until all services are online, and check your Sonos.

Note: If you see a prompt asking you to sign in, use the same email that you’ve inserted when connecting your Sonos Era 100 to the app for the first time.

3. Erase All Sonos IP Addresses

There is a known problem with Sonos speakers and the “Not Registered” problem, especially if you had another Sonos speaker paired to your router before.

The problem translates into an IP address conflict, preventing you from adding more speakers to your Wi-Fi router’s reservation.

Hence, many people confirmed that removing all Sonos IP addresses from the router’s settings helped, and they can finally register their speakers.

You must know the Sonos speaker’s MAC address, so check on the bottom of all the Sonos speakers and note down the MAC addresses.

When you have the MAC addresses, log in to your router!

3.1 How to Log In to Your Router’s Interface?

1. On a computer connected to the router, open a web browser!
2. In the URL, type “192.168.1.1” and sign into your Wi-Fi router.
3. Info: By default the login name and password are both “admin.”

3.2 How to Erase Devices via MAC Address?

4. When you’re in, go to the Network tab or the “Advanced” pane.
5. You need to find the DHCP server settings for your Wi-Fi router.
6. There you will see the “Reserved Addresses” of all your devices.
7. Then, erase ALL Sonos speakers, judging by their MAC address.

This will unpair your Sonos speakers from the network, and allow a fresh connection, so open the Sonos app and follow the steps.

5. Reinstall Your Sonos Application

If your Sonos Era 100 appears as “Not Registered” even after trying all the previous solutions, all evidence leads to application-related problems.

So, the next best step would be to reinstall the Sonos app from your Android or iOS and test whether a clean installation will fix the issue.

When ready, your Sonos Era 100 speaker should be registered.

Note: If you’re prompted to “Add” a new speaker, try pairing your Sonos Era 100 again!

6. Forget the Sonos Speaker System

Another thing to attempt against the “Not Registered” bug with Sonos Era 100 is to forget your Sonos system through the Sonos S1 Controller app.

So, this is very helpful if you have multiple Sonos speakers, spread around different Sonos systems, which causes the registering problem.

To forget your Sonos system, you only need to go to the “Settings” → “System” → “Forget Current Sonos System.”

Note: This won’t work if your Sonos Era 100 has been connected to only one Sonos system!

7. Factory Reset Your Sonos Era 100

If nothing helps, and you’re unable to register Sonos Era 100, it’s time to perform a factory reset on your device, which will resolve the problem.

The factory reset process will ultimately remove your Sonos Era from the system, and provide you with the opportunity to set it up from scratch.

Here’s how to factory reset Sonos Era 100 in easy steps:

1. First, unplug the power cord of your speaker.
2. Then hold the Bluetooth button continuously. 
3. While holding, reconnect the electrical cable.
4. Wait until you see the orange and white light.
5. Then, you can release the Bluetooth button.

That’s it. Your Sonos Era 100 should now be factory reset and when you pair the device again it should be registered.

If not, perhaps something with your speaker is not intact, hence the best next step would be to contact Sonos Customer Service and discuss more possible resolutions.

Quick Tip: If the Sonos Era 100 is covered by the warranty, contact the local merchant instead!
