So now that you have the debug info file (yes there is still a lot of info in there even without the debug components) you can go to the Ruckus support website at https://support.ruckuswireless.com. Log in and look for the Log Analyzer in the Tools section. Click on that and when the page comes up you can load the file. If the logs go back far enough you should be able to determine what was happening during the time of your AP disconnect issues.
Let me know if you have questions.
