Long story short: we have been tasked with setting up a makeshift event space on very short notice. 4 AP325s were newly installed in this space, alongside a couple of nearby existing 215s. After a quick test run of connectivity today involving 200ish people, we found that 2 of the 325s consistently had 70-85 clients associated (mostly on 5Ghz) while the other 2 325s had 10 or fewer clients associated. The entire space isn't huge (100ftx50ft) and test devices were evenly placed around the space.
Any ideas why so many devices attached to so few APs? Load balancing in general isn't an issue here, but then it's rare that more than 25-30 clients would hit a particular AP. Controller is running 6.4.4.22 (yes, yes, I know). Thanks for any insight you may have.
