Query: power adapter stopped working after two days; not a bridge

The AC adapter stopped working after two days. I verified it was the AC adapter because the power light turned on if I drew power from the two USB cables provided (as an advertised alternative to using the AC adapter). As a secondary note, I wasn't successful at using it as a bridge for connecting more than one device to it via a switch. It only connects to the first device. I don't believe it was designed to be a bridge. I got the Linksys WET200 instead for that.
