Scanning heavily depends on the RF environment and the hardware. In our
testing ath9k takes stupid long to scan for example.
But in a sort of best case scenario, using limited scan and no mac change, iwd
connects in ~300ms. People have reported that they have not finished opening
their laptop screen and they're connected, so at that level of latency, every
millisecond is important and totally worth fighting for. Randomizing the MAC
would penalize our connection times by 2X (300 ms at least). And Android folks
have reported the penalty to be as high as 3 seconds. So this needs to be
fixed. And do note that this is a feature every modern OS implements by
default.
Randomizing the MAC is a stupid decision.
Do you realy expect that this will add something to the security?
It allows one to be more anonymous.
Thanks,
