I don't expect you can get any reasonable advice based on your description.
There is no information about what kind of problems you have, and no useful suggestions can be made.
Instead of rebooting every bit of hardware (will most probably not help with enterprise grade equipment, it is useful mainly for SOHO, as UBNT),
you need make systematic testing to understand which part of the system fails -- is it problem with PC, with connection to AP, connection between AP and router, with router or Internet connection.
Problems you experienced may even be not related to power outage at all, but it is impossible to say based on your description...
So if you need help, provide as much details as you can, and make systematic troubleshooting to pinpoint culprit - find, what actually fails?
Is it latency of connection, or disconnection, or low bandwidth -- what exactly happens when "connection is out"?
