I am not sure if this has been discussed in here before, I was unable to find anything matching what I intend to do.
Anyone familiar with Cisco Aironet or some other big Wireless vendors will know they have software and hardware to monitor beacons from any wireless device nearby a Wireless AP while still being able to accept clients and function as an Access Point.
Mikrotik does this natively by putting a wireless interface into Sniffer mode which I assume changes the interface to promiscuous/Monitor mode. The problem with this is it then no longer broadcasts and accepts clients in traditional AP/Master mode.
So this is where as far as I can tell unless I am missing something multiple radios are required. I believe cisco get around this with add-on WSSI Module which most likely adds another radio (or two if its dual band)
I want to try replicate this with Mikrotik but so far it seems too expensive to use a single routerboard with 4 wireless interfaces (2x 2.4 and 2x 5ghz)
Using 2 routerboards might be cheaper but then I would have to find another enclosure or just install two enclosures together.
Has anyone done this? Is there an easier /cheaper way?
