Great story from Ernie Smith about the router everyone in America owned in 2004: The Linksys WRT54G that eventually went open source by accident.

In many ways, the WRT54G router series has become something of the Nintendo Entertainment System of wireless routers. Coming around relatively early in the mainstream history of the wireless router, it showed a flexiblity far beyond what its creator intended for the device. While not the only game in town, it was overwhelmingly prevalent in homes around the world.

Although much less heralded, its success was comparable to the then-contemporary Motorola RAZR for a time, in that it was basically everywhere, on shelves in homes and small businesses around the world. The WRT54G, despite the scary name, was the wireless router people who needed a wireless router would buy.

I still have some of those today, still fun to hack!
