My result are the same as Larry: I got my board running for ~4 hours and there was no disconnect. For part of the time I was doing (some) activity, for around hour machine was idle. I also did suspend-resume cycle. System: Ubuntu 15.04 (from usb stick), kernel 3.19.0-15-generic, x86_64 Machine: MSI AM1I, Sempron 2650, PCIe to mini-pcie "wifi" bridge (with antenna connector and proper RFKILL wiring). Are you able to do more troubleshooting? Perhaps try different AP/Channel/mode, (dis)connect power cable from laptop etc. I'll try to make another reproduction attempt, as without being able to reproduce it I will probably not be able to fix it.
