First success using mac mini. Could record some data of amazon echo. Setup gues network on router without any security, this enabled some capture since no keys had to be configured or handshakes captured (would be an issue without any channel controll) Issue: Channalhopping -> missing a lot of traffic To avoid channelhopping: Somehow fix the channel on router.
By leaving out any authentication/security config in hostapd.conf one can create an unsecured AP (on the usb wifi card) on my linux machine to. Having an open auth AP seems fine for this use case. In the end this seems to be the way. For doing experiments we want to record all traffic. For this we cannot loose traffic just because we are not connected. This is why we'd want an access point we controll fully. We don't want to rely an some other router. But even then there would still be much manual config (channel, making an open access vlan or whatever).
Essentially we need to know the channel exaclty and don't want to deal with any more cryptography than we must. So, ideally we can create an AP on a laptop or local computer, using a low cost wifi adapter. (Since we are talking about testing IoT devices we must rely on wireless internet, since this is how virtually all of them work.) We should be able to configure that device to be an AP. Then we need to forward to whatever interface the experiment computer has internet access to.
