My patch by means of a parameter allows to come back to the original interface combination (before f019f4dff2e4 and not the current one that you comment), so as I commented, this is the interface combination that I am finally using to setup the two APs: # iw list | grep -A4 "valid interface combinations:" valid interface combinations: * #{ managed } <= 1, #{ AP, P2P-client, P2P-GO } <= 16, #{ P2P-device } <= 1, total <= 16, #channels <= 1, STA/AP BI must match, radar detect widths: { 20 MHz (no HT), 20 MHz, 40 MHz, 80 MHz } HT Capability overrides: And I repeat that with that, my setup is working (no error log). > If chip support DBS, station interfaces max is 2 that why you can't up > the 3rd managed type interface. You better add interface with ap type. Ok, but as I commented this is what I am doing. Just to clarify, only with your proposed interface combination I am getting problems with a 3rd managed type interface. > 2.4GHz works fine also. That is great. Ok, at this point, as I need my setup, in order to allow me to debug and get the differences, could you share how you are configuring the two APs to test and debug here?
