[Ns-developers] Bug in ApWifiMac

[Ruben Merz]

Thanks for the report,

I created bug 1080 (http://www.nsnam.org/bugzilla/show_bug.cgi?id=1080). 
Could you let us know which version of ns-3 you are using? And if you 
have a ns-3 simulation file that we can use to reproduce this bug, we 
would be glad if you can attach it to the bug report.
