This is the log that is appearing: [ 61.909165] 8021q: 802.1Q VLAN Support v1.8 [ 62.227530] ath11k_pci 0000:01:00.0: failed to create vdev 3, reached max vdev limit 3 It is appearing after configuring both APs when only one AP is up and when both are down (see my previous 'iw dev' outputs). > I'm not very sure if you add all interface with managed type, and do > "ifconfig xxx up" before running hostapd. Yes, I am setting the link up before running hostapd. >You can try add second and third interface with > "iw dev xx interface add xx type __ap". And yes, I am doing like that for both APs. Please, take into account that everything is working with the old interface configuration and when it is set with the parameter (no error log), but it is not working for me with your interface combination. Have you tried with 2.4GHz band? Thanks Best regards Jose Ignacio
