Hello!!

I have been used my spark core around 3 months, but recently my spark doesn´t connect to my network home (it stays flashing green). I tried a lot of things, like reset factory, I power it by USB port. What can I do?

Thanks.

Thanks for your anwers, i did the previous steps and now my spark is already connected to my network, BUT when I flash a program (even if it´s a very simple one) the web IDE says:  
Request Timed Out  
Flash unsuccessful.

And my Spark never flashes magenta. (My IDE says my spark is connected and I did a factory reset but still doesn´t flash).

Core or Photon? What code is running on the device?

Core. And the code is for example “Blink an led”

That’s the code that you tried flashing i guess? I meant what was running on the core.

Anyways, perform a factory reset and try flashing the Blink an led example again 😉
