RouterOS version on cAP ac when installing 'wifi-qcom-ac"

I have a cAP ac running RouterOS v6.49.18 and wish to replace the ‘wireless’ package with the ‘wifi-qcom-ac’ in order to gain 802.11r functionality.

Do I also need to change RouterOS version, or will v6.49.18 work fine with the ‘wifi-qcom-ac’ driver?

Thanks in advance.

Unless you are able to find the wifi-qcom-ac driver in any V6 package, you are restricted to use V7 :sunglasses:

Wave2 does not exist in ROS V6.
So there’s your answer.
