Had a spark for a while and always had to use wifi to connect to fly it, just bought a remote but now can't use it since I can't activate the spark.
Everytime I have tried I get a network error. Please help.

HiForestFM, if you have used wifi to connect to fly the drone, the drone should have already been activated, no need to activate it again. Please update the firmware of the RC and then link them, you should be able to fly the drone with the RC.

How to link Spark to the RC?
Press the Pause, Fn, and C1 buttons at the same time. Once the controller starts beeping, release these buttons. With Spark powered on, press and hold the battery power button. When you hear Spark beep, release this button. Linking is now complete.
