Query: This device simply didn't work.

I'm sure this device worked for some, but after hours of trying to get it to simply connect, I finally had to send it back. It comes with a small manual, and even smaller troubleshooting guide, and the 24-hour tech support is only equipped to deal with linksys routers. Even then they just give a default answer: "we have a deal with your ISP, you should call them."
