I completely agree that we need to ensure that whatever product we hack on is available at office depo, and frys, and so on. Preferably worldwide. I was happy with the deployment and popularity of the wndr3700v2 and 3800, I was generally able to find them on retail shelves no matter where I went until about 6 months back. > for now I've dropped their equipment off of my vendor list, the only > dual-band equipment I see from them is in the $250 range That's why they aren't really on my list for cero's main target, either. However the yurtlab (which, given funding and time) will eventually have a few of everything, and I also hope to get some good numbers back from the next "the gathering" demoscene. So we're back at switching to the 3700v4, or finding something from a buffalo or TPlink that still uses the ar71xx and ath9k that's in the 3800. I'd evaluated one of the buffalos (yea! more flash! Boo! lousy antennas and build quality) about a year back... or building something from scratch and getting it into wide distribution... or going in some radical new direction entirely. > > David Lang --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
