Hi,

Sorry for this necro post, but since 3 days I tried to specialized my Omega2+ for wifi scanning/attack (research).

As you can see in this post (https://community.onion.io/topic/2247/demo-wifi-ap-sniffer/6?_=1589203829729) , @tommaso-tani has tried unsuccessfully to enabled the monitor mode.
Furthermore, as you can see on mediatek (https://docs.labs.mediatek.com/resource/linkit-smart-7688/en/limitations-and-known-issues), the official driver does not support monitor mode.
I'm afraid to have to say that Omega2+ is not a good candidate device for wifi security research
