Cannot join AP9130 to WLC

[Leftz]

Hello, We have C9800 wlc with APs9130e which work well for many months. Now We want to add APs9130i to the network. But we have issue to join the new AP to the WLC. The log info from AP is showed as below. Anyone can help to provide some suggestions? Thank you

Look at the back of the AP.  Does this AP have a manufacturing date of September 2022 and later?

Hi is it the AP or the WLC itself that we should upgrade!?

[balaji.bandi]

If this is new AP model, then you need to upgrade WLC  to latest version to support new model vX 

check below matrix :

Thanks, I read the documentation and it is very clear now.

If that works for you, no further assistance required, can we mark as solution to help other community member can use this as reference if they have same requirement.
