Next year we are moving to a new location (arguably we outgrew the current location quite a while ago, and this year we had people sitting on the floor in rooms, hanging out at the doorway, and filling the overflow rooms where we live-streamed the talk as well) the new location is considerably larger (~2x the space), so we will have to buy a lot more APs. The WNDR3800 is not available in these sorts of quantities, so we will have to buy something new. We are looking at two major options 1. going with something similar to what we've been running (say the 3700v4) 2. switching to ac/mimo APs since we will be needing ~120 APs for next year, the cost of the different options will be significant. At this point we are just starting to look and figure out what's available, what sort of price difference there will be, and what the advantages of the better APs would be. I'll probably purchase some samples to experiment over the next few months, but we won't make the mass purchase of whatever until late in the year. David Lang
