Since EAPOL frames are normal data frames they are treated by the rate
control algorithm as such. Thus it can happen that the rate control
algorithm chooses an inappropriate rate (minstrel_ht uses MCS rates for
example) for the 4-way handshake and under low signal conditions the
handshake may time out.
To fix this issue always treat EAPOL frames the same as management
frames and send them with the lowest available rate.
Have you tried preventing minstrel_ht from using EAPOL frames for probing
different rates instead of forcing it to use the lowest rate?
Nope. I'll give it a try soon.
Felix, what rate is used by minstrel_ht if there are no statistics yet? MCS0?
Yes, rates default to lowest until better ones are available.
