Wx6120 extender, says incorrect password

[Lilybetty]

I have the right password, it keeps saying it’s incorrect, please help
I’ve done the reset and that didn’t work

You have the EX6120? 

What firmware is on it? 

What router is it connected to? 

Did you set it up using wps or using the installation assistant?

[Lilybetty]

Yes that’s the model , I don’t know what you mean by firmware ?
Connected to a Vodafone router using wps as just got an error message when on computer
Thanks

firmware is the software (firmware) running the device. 

Vodafones wps function doesn't always work as it should. 

Try factory resetting the extender (push and hold reset for 7-15 seconds while extender is powered on), then reinstall it using the installation asssistant and NOT WPS.

All the green lights are on so I presume the wps worked. I tried resetting it but I can’t do the computer way as I get this screen...

When you were resetting, did you push and hold reset for 7-15 seconds while it was powered on? 

WPS can get coded different and even though the colors show proper, it not work right. 

[Lilybetty]

Yes held for 30 seconds to make sure. I keep trying every few days but still it says password incorrect

Have you tried hardwiring into a pc/laptop (disable the pc/laptops wifi) and setting it up that route?
