In another Atheros-based radio system, I noticed that “Virtual APs” have nearly all the capabilities of the physical card (except frequency and modulation), and a disruption to one VAP does not disturb other VAPs on the same card.
This extra VAP functionality would make a nice addition to RouterOS.
For example: It is possable to have “Virtual Station” interfaces, along side “Virtual APs”, . It is also possable to run a scan with one VAP (only on the current channel), without disrupting connections (AP or Station) on other VAPs.
