I purchased my router about a little more than a year and a half ago. Draft 1 I would assume.
It only comes up because I'm getting a new notebook from work and don't have the patience to find out if it would be compatible. It hadn't mattered to me before because I only had wireless-G in my laptops (like I said before I was buying for increased signal not speed.)
In addition, my lab only buys macs. The new macbooks list as wireless b/g with a note that you can buy the enable in the fine print. While it is only $1.99, I can't believe they would make me pay for the patch. The weak ass tax excuse for having to charge would not be an issue with new hardware.
I'll find out soon if N is enabled out of the box, if people are curious I can post an update to this thread when I find out.
