Go to "Settings"
Under DNS, clear away any existing entries and replace it with the router's default DNS (e.g. 192.168.1.1 same as the Router in this case), or you can put in Google's DNS (22.214.171.124 or 126.96.36.199)
Go to www.unotelly.com/quickstart2 and check the set up status of the device, to see if you get the "UnoDNS Setup is incomplete. Please complete UnoDNS setup." message. If this message appears, UnoDNS should be sucessfully removed from your device.
