I have a WRT54G router, I have had it for a year now and it works (worked) fine. I recently unplugged the cable and to plug it int my laptop to download a big file directly, then plugged it back in to the router and now the wireless doesn't work! The signal is excellent, the speed is 54mbps but the internet connection status reads: "authenticating", and the internet won't work. It says unable to access host. I reset the oruter, rebooted everything, etc, and still it won't work. Any ideas?
