I am not really sure how a charm works, but I know this works like one. :)I was able to get online rather quickly thanks to the quick install guide that came with this router. I have been running this router for about 4 months now and it hasn't had any hiccups since. I configured it for my cable connection, it connected, and I've been connected to the Internet from then on. I've expereinced no downtime, and can share files, Internet access, and printers with great ease. This router is the most inexpensive out there and performs just as well as any other. i don't see why you wouldn't get it.
