We've been moving our (other vendor) AP's over to MikroTik RB433AH's with R2N's and I have to say it's been a very smooth and pleasant experience.
However we seem to have uncovered a shaping bug using RADIUS auth via security profile.
AP TX shaping is spot on. ~384kbit
Client TX isn't shaped. ~1.6Mbit
We obtained these results testing with ftp to a distant site.
See the attached client registration:
Should be AP TX 384
Client TX 256
