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

Hi there Philip,

 

Thanks a lot for your guide. I’m having the same problem and looking for a fix. I tried resetting my wifi password as you suggested and doing the factory reset but for me it doesn’t seem to work. It still says my wifi password is incorrect, even though it is. 

 

Did you reset the password of your wifi before or after the factory reset?

 

Cheers

Hello,

I had exactly the same problem, in my case the solution was to change the type of 2.4Ghz network. 

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.

Check if it doesn't work for you as well.

 

Best

having this issue too. Pawel, I’d love to try what you put, but I’m not sure I entirely understand it.  you’re suggesting changes on the router, right?

Changes to the radio section of the router settings, it should offer a list of possible modes and let you pick one Sonos will work with.

Hi

Recently bought Sonos One and spent 2 hours trying to configure on wifi. Cable worked fine  

It complained about the password, even if I changed to the most simple one.

Pawelb helped me in the direction.

I knew I had a special config regarding the 802.1n/b and so on in my router.

When I turned the net type to Automatic the password was fine. And the speaker was installed.

 

Didn’t find anything regarding this from Sonos themselves. BAD!!

Thanks a lot

I had this issue as well, and tried the above to no avail.  What worked was creating a new SSID with open authentication, factory resetting the play 1, connecting it to the new SSID, then adding mac authentication to the new SSID.  Hope this helps someone.

I had the wifi password incorrect problem with my Sonos One. I called Sonos for support but they were unable to debug my problem.  They finally said it was a router problem or maybe it was interference from my cordless phone.  I tried putting the Sonos One on a guest network but that didn’t work either. I finally decided to reboot the router (I didn’t want to do that since every other wifi device was working fine) but the reboot fixed the incorrect wifi password issue.  I didn’t have to change the wifi password.  

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.
