well, they most certainly are not a switch, which makes them a hub. packages are essentially all broadcasts, LAN members filter by the MAC Address of each packet. This is unavoidable with the wireless medium. And you have way too much faith in the transport layer validation, if you think the UDP/TCP Error Code Fields can counter all package corruption. They catch a lot, but most certainly not all.
And thats the problem - there are just so many corrupted packets on WLANs.
The faulty packets are mostly dropped in the application layer on fully fleshed out systems, but this is exactly why the niche vendors with their closed source controllers are so error prone in that regard. And i'm merely pointing out the to me most obvious problem. There are way more edge cases around.
