You are right about the caps. if the unit has a seperate power supply it would be better to replace it, you may also have trouble getting into the case if it is sealed well. It could also be a bad diode etc.

Hi,

To resolve the problem, I used my Iphone instead of my Computer to connect to the network.
On the Iphone the network "None" was not show so I've manually connected to this SSID with no password.

On the Iphone I then go to 169.254.1.1 to relink to my home WIFI :)

Hope this will help :)
