It's well known that the adapter that comes with 2wire Gateway fails, but maybe it is the gateway killing it. The original wall adapter that came with the modem failed, which was 5v 2A SMPS.
I chopped the wire off and replaced it with a 2.5A 5v adapter from another router. Just now, I noticed my internet was out and it smelled a bit funny. I checked the router and lights are flashing funny, then I noticed the adapter had bulged as the capacitor got hot, expanded and softened the case.
One of the capacitors in the D-link adapter I used was bulging on top and melting the case. The other capacitor that I can see inside the adapter opened and vented on the top and these are 16v 105C capacitors. Is it the 2wire that has some way of overloading the capacitors and destroying them?
