Ruckus Switch ICX 7150-C12P shows disconnected in Unleashed - Slow Internet connection

[GBS]

After a recent power outage, my Ruckus Switch ICX 7150-C12P shows as disconnected in Unleashed ios app.  Also, the internet connectivity over the broadcasting Wi-Fi channels on Access Points (Ruckus Zone Flex R320) is extremely slow.  I tried the recommended power re-cycle and factory reset on the switch but could not be able to fix the problem.  The lights on the Switch and Access points are all GREEN.  Please assist to resolve this.
