AP in the problem area is AP-105 - 2.4GHz is channel 11, 5GHz is channel 48. 3 clients using 18.04 Kbps. dBm of -67, -69, and -56
AP at the intersection of the L is AP-93 - 2.4GHz channel 1. 0 clients on this AP.
AP at top of the L is AP-105 - 2.4GHz channel 6, 5GHz channel 153. 1 client on this AP, using 0.006 Kbps. dBm of -78
Of course I'm still waiting on client information on the users that are having the problem.
As far as the survey goes, I'm pretty much in the same boat. When we moved into our new building it was recommended that we put about 30-40 APs per floor - building is approx 410' x 125' and 3 floors. That was the recommendation from Cisco. We basically ignored that and used the ever so scientific method of drawing circles on the floor plan.....using common sense when it came to elevator shafts and stairways. We have a total of 27 and manage to cover all required areas.
I did have inSSIDer and Ekahu heatmapper that I would use if I had to make a site visit, but lost that in my upgrade to Win8.
I've got 180+ locations, with about 100 of those in Airwave and having been adjusted for coverage using Airwave suggestions and previous real world experience. To date I've NEVER had any of these problems related to our equipment. We haven't done any firmware upgrades in at least 5 months, so I can't understand the recent complaints.
I'm basically at my wit's end of dealing with users that like to complain, yet refuse to provide any details. I'm currently working on an AC migration, so I can't drive 250 miles to a site to sit down with a user and find out the problem is with their equipment (really, isn't it always the user's equipment?)
Unfortunately we don't have license for WIPS or RFProtect to give me any better insight into what is happening at my locations, but we've enjoyed 10-12 years of relatively problem-free wireless access.
Sorry for the frustration....this is 3rd office I've had to deal with this type of issue - all involve users sitting no more than 20 feet from an AP, and all involve users that refuse to provide any information or do anything other than complain to upper management that "nothing works....at all!," and all involve APs that appear to be working fine for other users in the area. :)
