I have a 60g PS3 with upgrade 1.54 and a Linksys WRT54G version 4. The first night I got my PS3 the wireless worked fine. I scanned for the SSID and it found it with no problem. I was playing Resistance online and downloaded games with no problem. The next time I turned on my playstation it wouldn't connect. It fails to obtain a IP address. I've tried to set up the connection manually,reset the router, update firmware, adjust settings for the router but nothing works. The little green wireless icon on the PS3 doesn't even light up. I've tried peoples tips in the forums for settitng up the connection but I can't figure it out. Nothing is working. My laptop connects to the router perfectly fine. If any one has any ideas, please let me know. Thanks!
