Luis,
I understood the difference between the two lists.
I also understood from your previous remarks that because I had a
single stream chip mcs7 was all I could get.
Does this prevent me from using 11n though?
I am currently doing a compile on another laptop which I am pretty sure
is multistream, so will test there too.

I also noticed that from the list you get
HT MCS set: ff 00 00 00 00 00 00 00 00 00 00 00
but on the multistream you get
HT MCS set: ff ff 00 00 00 00 00 00 00 00 00 00
What does the second set of ff mean?

Thanks,
Brian
