We have an issue which we cannot seem to figure out. We recently upgraded our AP's to 7522's in all of our buildings (370+ AP's). Users are complaining that their handhelds keep dropping their connection (mainframe and RDP). Whats interesting is that users say that it was better on the older 650's we had in place before the upgrade. We have had site surveys done in several of our buildings and added AP's where recommended.

Any idea on what to look at next?
