@d0ugmac1 same group of APs.  It's strange, because the one that's problematic was the first that I set up and performs terribly.  The other three are perfect, however.  Yesterday just to test I added a fifth network, and it works perfectly as well.  I did look into whether having this many wireless networks on the same set of aps would impact performance, and from what I've found it shouldn't be an issue based on the number of aps (6) and the number of networks.
