I tried everything (reset router, use the Particle app, command line, update firmware ) to activate my Photon at home but it keeps blinking green.
So I went to a friends house and used their wifi connection and big surprise: all went fine!
I am using an ATT U-verse 3801HGV router and there seems to be a big communication issue.
Anyone experiencing the same issue?
ps. I have 2 Cores and they work just fine with the router.
