Summary: Because of its open-source, Linux-based software, developers have created their own firmware that lets this router do all kinds of things it was never designed to do, such as control bandwidth usage and signal power. Linksys supports only its official firmware, however, so if you change it and run into problems, you'll be on your own.
Pros: Good performance, Tried-and-true reliability, Easy to customize
Cons: Uses older technology, Not as fast as wireless-N routers
Excerpt: In our house, the kids had their own computer and their own dial-up connection to the Internet, yet they were always clamoring for a turn on my computer. Why? Because I had the DSL "high-speed" connection. Not only was there a restriction on the kids' Internet time (it tied up the phone line), their connection simply wasn't fast enough, they complained. Spoiled?
