If you have upgraded from V2 , have you re configured as new setup via AP mode from you phone or tablet and re entered all settings as if a brand new install.
If you have done this can you go to the IP address of device e.g. 192.168.0.34 and the status page comes up in your browser listing all the config items??
also did you set a admin user name and password?? and are they correct???
