Heya Cpt
Finally another stumbler in South Korea...WOOT. Yeah I've seen all the different card there at the electronics mart, settled on a tried and true Orinoco Sliver, two as a matter a fact for about 90,000 wons for both. Got does before the lastest version of NS so haven't played around with the newer supported cards. If you did a search on Buffalo in the forum you would have found that certains models do work with the newest version of NS. Tough crowd here so do lots of searching on the forums. heres a link
Cards that work
Been wardriving Korea for the past couple years, and will be coordinating this years effort again, hope you can join in..
