Always wrong password

[gempir]

I have 2 almost identical raspberry-pi's set up which are supposed 2 networks. Both use the same wifi stick and the same version of hostapd, same dhcp, etc...

On 1 device hostapd will work like intended

On device 2 hostapd doesn't work as expected. I always get an invalid password response but no logs even with -dd or syslog shows anything useful.

This was tested with v1.1 and v2.0 stable

I ran into the same issue, but was unable to solve it. I reckon you're on jessie, so the fastest solution is to get yourself a wheezy installation or at least a 3.X kernel.

I'm now on a Wheezy with a 3.12.22+ kernel and everything works like a charm. A nice tutorial can be found here

Hello,

I have the same problem, I use a Pi Zero V1.3 so it's not possible to have Wheezy with the kernel 3.12.22. I think it's because this version is to old for this pi.

But, finally I found a solution here with the official hostapd: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=152603&p=1010357#p1010357
