Bad wireless Speeds

I am having an issue with wireless settings. I have worked with hundreds of wireless routers / ap's/ radios, I have my CCNA, and Network +, so I have tried everything i know. I cannot for the life of me figure out what precisely controls wireless speeds. The max i can get is ~25 Mbps up or down. On most devices, I cannot get more than 5 up or down. The obvious answer is the standard your running on, a, b, g, n, ac or other uncommon standards, but even in N and AC, i cannot get the throughput i need. I've checked link speeds, duplex settings, interference, but I cannot get good throughput. This isn't unique to any specific model, just in general. Just to study, I bought 10 identical access points, put them on the same network one at a time. only 1 of them was delivering 98%+ throughput. the rest were all at 5-10% of the network's throughput. I've messed with QoS and WMM, to no effect.

I haven't taken my wireless configuration certs, maybe i should, but what the heck affects wireless speeds? What settings do i need to adjust? Is it just that most radios are bad? the 3702 Aironet AP's from cisco never fail, but most of my customers cant afford $1000+ APs
 
In my house speeds are very dependent on distance. I get fantastic speed (30-40 Megabits) when I'm close, say within 20 feet or so, guessing) but add another 20 feet and I'm trickling (this is on Verizon router or on a cheap Linksys AP). This is on my 85 megabit Fios line:)
