EX7000 won't allow wireless connection after firmware update

I recently updated my EX7000 to Firmware Version: V1.0.1.80_1.0.144. After that firmware update, the following devices were no longer configured/connected as they were prior to the update:

• 2 - Honeywell WiFi Thermostat, model RTH8500
  • I attempted to reconnect the thermostats following the Honeywell User Guide. 
  • I follow the steps, but the Thermostat displays "CONNECTION FAILURE" upon completion.
  • I connected one of the thermostats to my AT&T U-Verse Modem/WiFi Router so I know the issue is with the EX7000.
  • The other thermostat is located beyond the range of the AT&T U-Verse Modem/WiFi Router.
• 3 - FDT Wireless Security Camera, model FD7903
  • I attempted to connect the cameras following the FDT User Guide. 
    • Following the setup guide, I connected a camera to the EX7000 using an ethernet cable successfully. When I disconnect the cable, the camera does not connect via WiFi as it should.
    • I connected one of the cameras to my AT&T U-Verse Modem/WiFi Router so I know the issue is with the EX7000.

I'm fairly technical, but I'm stumped. The following devices reconnected to the EX7000 WiFi with no issue after the firmware update:

• iPhones
• HP 6700 Printer
• Direct TV
• Roku
• 5 Woods WiFi Timers

Any help is greatly apprectiated.

Thanks,
