Your first question.. It would appear the client in question 00:1e:7a:bb:8e:81 is not supporting your basic data rate.

I would track down that client (if you can and see what type of card it is and how it is config differently from our other clients)

When a client auth and ass to a wireless network it passes specific information, identify information if you will, what type of security, data rates etc ...

Ive never seen question number 2... I will get back to you unless someone else anwsers it before then...
