My old router died out last Thurs. and I didn't have the extra cash to buy a new one last week, so I bought a new one today, the Linksys WRT54G. I get home, connect everything, restart it all, reset the modem, go through the Network Diagnostics scan and my Mac still won't connect through a router. Meaning either I did something wrong in the diagnostics or I went out and spent $73 on a router that doesn't work, any ideas????????
