Problems with AP330 and AP121

[CornéW]

We have many AP 130 in ExtremeCloud IQ and they works fine.
We have also AP330. With these AP's we have problems. They are online but the internet works very, very slowly. All settings tried but de problems won't be solved. All AP330 gives the same problems. I also tried one AP121. The same problems. AP 130 works perfect.
Someone any idea what we do wrong? I'am desperate.

Hello Corné,

Are you running the same OS release on all these AP's?
And is it one of the current releases?

Also, since none of these models is brand new, I guess the AP's were previously used in another environment.
Did you try to factory reset them?
