There are many ways by which you can overcome or get rid of the error that you have tackled while setting up the extender through mywifiext.net. When you face this error, if the range extender is far away from the router, then you have to plug in the extender near to the router, lets say, within the range of three to five feet to the router, reason being , for the initial set up the extender requires to be near to the router so that the range extender can be synced well enough to the router. Once you plug in the extender within the range of the router, you need to reset your extender by pushing in the reset button for 25 to 30 seconds. The lights will keep on flashing until you have one solid green light on the power LED panel of the range extender. Now you need to start the configuration process all over again by getting on to mywifiext.net. Then finally you will see the connection confirmation at the last step of the mywifiext.net set up.
