- Actually the restriction is “Old 802.11ac ARM CPU devices* … * wifi-qcom-ac: Audience, Audience LTE kit, Chateau (all variants of D53), hAP ac^2, hAP ac^3, cAP ac, cAP XL ac, LDF 5 ac, LHG XL 5 ac, LHG XL 52 ac, NetMetal ac^2, mANTBox 52 15s, wAP ac (RBwAPG-5HacD2HnD), SXTsq 5 ac” : the RB4011iGS+5HacQ2HnD-IN is not on the list of supported devices. Also the writing is on the wall “New 802.11ax devices … Old CapsmanOld Capsman [:] routeros + wireless [;] Actually old = dual. Loses built-in cards ; Running both capsmans at the same time [:] routeros + wireless [;] Loses built-in cards”. I do know that RB4011iGS+5HacQ2HnD-IN is not a 802.11ax device however it is quite a special snowflake therefore it would not be that surprising if it turned out that it is a bit more special and act as the 802.11ax devices do in this scenario. Nevertheless I do hope that the issue will be sorted out sooner rather than later, however I would not have my hopes up (considering the still sad state of routing protocols in v7 - documentation included).
On a personal note, when I started to use MikroTik I intentionally separated the wired and wireless (at the cost of higher initial CAPEX) in order to avoid the pitfalls of all in one solutions.
