Hi Giovanni,
Could you check the switch port configuration for problematic AP and make sure it is same as other switch ports where working APs are connected?
Are you using managed switch? If yes, disconncet the network cable from switch side for problamatic AP, configure this port as access port with VLAN of SSID-A and now connect a laptop.
If laptop gets and IP then it means switch side configuration is correct.
