Geeetech

I use canon... So how is this connected to the question above?

Thanks.

How do I do the factory reset advise.

My Yun shield from Geeetech is acting up bad. I don't know what to do.

I powered up with a 9v adapter capable of up to 200mA. I fired the thing up and logged into it.
After changing password and setting it up to connect to the AP. The wifi failed up to date.
I have tried the 30 sec reset and all ...
