Dear Sonos-ers!

TLDR;

Issue; “Incorrect password” for wifi set up even though you enter the right password.

Fix; 

“Incorrect password” → Factory reset → Ethernet to router → create new router password for network on router → set up speaker again with Ethernet still in → “create wifi network” via app → Enter your new router created password → should work!
I am creating this as hopefully my first and last post on this community thread.

=============================================

I have spent the last 2 hours troubleshooting this issue, so creating this in the hope that this helps you further. Hopefully this will improve my karma!

I went to sleep last night with the Sonos One speaker working perfectly, with a smile in the corner of my mouth. Waking up, the Speaker was essentially a brick, went through the “whats wrong” troubleshooting several times via the app to no positive effect.

Then, I eventually got the “enter your wifi” option, entered my password, and got “password is incorrect”. I thought I might have missed a character, then realized no, I wasn’t at fault here. I even used “forget network” on my phone to make sure the password did work.

So I went to the extreme of connecting the sonos via Ethernet(digging through several drawers) and connected and…. yes it sprung back to life!

I was so puzzled, the wifi was not working, but the Ethernet was. So I searched this, and went through several threads, filled with raging sonos users, and others using the classic “have you turned it on/off” trick. 

So finally, I logged onto my router, changed the password on it for the entire network .

Then, I factory resetted the Sonos One (steps in other articles), Ethernetted the speaker again, and then via the app, I used the “create wifi network” option. 

I entered the new password and HALLELUJAH it worked!

Why changing the password on the router worked, or why it somehow stopped working overnight, is a puzzle to me. I did go through some firewall settings on my laptop, I was messing with Stream what you hear, but not sure how they could have effected things here?

Anyway, I went through this pain so you don’t have to!

Great speaker, amazing mind blowing sound and features, but Sonos if you are reading this;

  1. No compatability with Windows audio? Why? This should be such an easy solution. Why only Airplay2/Apple compatability? I would like to not think this is some sinister way to get us to buy sound bars and other products?
  2. The community threads are a mess here, I don’t understand why they are allowed to be a forum for people to kill each other. Toxic users should be pruned, it makes for a terrible experience having to search through them. Like look at the replies on this; https://en.community.sonos.com/troubleshooting-228999/sonos-says-network-password-is-wrong-only-its-sonos-which-is-wrong-6831182
  3. After factory reset, the sonos controller DELETED all my presets and favourites, yeah again, this should be an easy fix!

Anyway, happy to have this up and running, and really enjoying the experience (now!).

Thanks,
Philip

I replied previously - I was having the “password incorrect” message problem with the Beam even though I have never had issues with the other Sonos products I have! 
 

I was able to get the Beam working again after doing factory reset by:

1. turning off the device, pressing the “reset” button (looks like the infinity symbol)

2. plugging back in the device and holding the reset button for 30 more seconds.
3. After that, I set up as a new device.

 

The above worked for a day but the device disappeared from the Sonos app a few hours later.

 

Has anyone reached out to Sonos support yet? I’m afraid that we might have to trade this device for one that might be more tested.


On Router I had permanently set 802.11n and SONOS did not pass my correct password. After the change to "mixed" (a/b/g/g/n) the application immediately accepted the network password.

 

Hi,

I would like to thank you Pawel for your tip. It works for me like a charm.
Changing to mixed was the only think I had to do.


Having this issue with the Beam. Installed it and worked fine yesterday. I have tried troubleshooting - the Sonos has created its own network - but I get an error that says the wifi password is incorrect even though I can log into the same network with the password. Will give this a try! Thank you.


Pawelb is my hero. Once I figured out how to find/change this setting in my router. Voila!  Accepted correct password and Sonos working on new router. 


This took me days to figure out unfortunately. Thanks to all before me... What worked for me: hooked up Sonos to Ethernet, checked channel setting in Sonos app network settings. It was set to 6. Then in router, updated firmware, set WiFi network mode to "WPA mixed" and channel number to 6. Tada...
