Right password, but keep getting wrong password for WIFI error

The strange thing is that it won't even connect using ethernet cable. It can't be the internet, as it was all connected before. I did a factory reset and now it won't connect, or even try to connect to the WiFi and when the ethernet cable is in, it's still asking for a password. Before anyone replies thati shouldn't have factory reset, I realise this now, but after reading Sonos help, it did say to do that if your app doesn't connect. Does anyone from Sonos monitor the community and helps?

Rarely, calling support is your best bet 

Going through the same issue.  Cant get past the wifi connection on my new era 300 surrounds. Getting the “wrong password” error even though it’s 100% correct. Ultra and sub 4 paired flawlessly along with every other sonos product I have. Did a hard reset on everything, attempted to connect on multiple wifi changes, tried hardwire to the router, updated my phone, tried a different device running iOS. Running out of options. Hope there is a resolution to this. I’d really like to get these surrounds working. 

Thanks @Masterchri, glad it’s not just me. I feel your pain though as it’s really frustrating and I still have no solution :-(

I’ve been having the same issue with my Sonos Move (1st Gen) since we moved house 5 months ago.  My 2x Beam’s and 2x Era 100’s don't have a problem with the new wireless mesh or when I reverted to the old mesh.

Like @DanNeedsHelp I have copy/pasted from the IOS wifi settings and typed the password but still the same error.  I have no special characters and no characters that could be confused for numbers, or upper/lowercase letters either. Its as simple as you can get.

I’ve spoken to technical and they tried reset after reset, refreshed the app, used the app on different devices (iPad/Android/iPhone) all with the same error.

They finally gave up and told me to phone in, but with an 80 min wait only to be told the same thing I'm reluctant to waste my time.

I purchased Sonos as it was the best on the market, if expensive, but I am fed up with all the issues since the app was updated. 

Any useful help will appreciated.

I am having the exact same problem, have tried resetting everything and it is definitely the right password. I called customer service and they were pretty useless, had me run through the generic stuff before saying it was my internet providers fault even though all the settings are as they recommend.  

looks like I may have found a solution! try uninstalling the app from your phone and reinstalling!

Seen other topics suggesting a “force close” to clear up Android App issues.

I had the same issue trying to setup my two symfonisk speakers, one used before and one new, in a completely new setting. Fixed it by uninstalling and reinstalling the app on my phone.

None of the above worked 😔 tried ethernet cable, reinstalled the app, rebooted router and other efforts but nothing. I now have three speakers which are expensive junk. Think it's time to get a Bose or Samsung soundbar.
