1.22NA. Running G only (most of house wired) with WPA2 AES. I want to try WPA enterprise some day, just for fun. The only complaints I have are in Nutz post, being the slight compatibility issue with Chrome/Safari and the odd way it treats ICMP traffic. My statistics are clean as a whistle, and would be alot more impressive if I wasnt resetting the router all the time to play with it. I can easily say its one of the most dependable routers I have had, just shy of my 4300 (dropps some wireless TX packets now and then, but thats mostly the brick wall sitting next to my wireless desktop)
