so I have a linksys WRT54G wireless/wired router. It's connected to an intel iMac with ethernet, and I connect wirelessly with my macbook. 2 days ago, all of a sudden, the wireless signal disappeared. The imac is still fine, but the router is just not broadcasting anymore. However, linksys does have a firmware update for this router, and I'm betting that will fix it. But... I can't install the update. It downloads as a .bin but cannot be unstuffed with stuffit or winzip. So I can't install it and can't get my wireless back. Any thoughts?
