What version of ArubaOS?

What kind of client device is this?

What kind of encryption are you using?

Re: Ptk Challenge Failed (seq num 0)

This message is something that occurs:

 

- When there is a certain level of interference

- When the driver on a device is not up to date

 

 

It could be either of the two or a combination of the two reasons.

 

I would also say to limit your SSID only to a single type of encryption, not two.
