Upload/download from a wired connection. I know that code can't be uploaded to the controller while connected to an access point joined to that controller.

You sure you don't have a firewall on the machine blocking ftp? If it is a bug, then if you downgrade to any other code, ftp would work. Have you been able to ftp on that same controller prior or is this a new controller?

yes it is not a firewall issue, tried with a computer behind the same firewall and ftp works perfectly. and yes it worked before on the same controller with 2 other older firmware versions.

I was referring to the laptop FW. Well there are no bugs showing for that code version. So I would have to say, open a TAC case and have them look at it so they can log it as a bug if indeed it is an issue.
