Internet with modem works but wireless router says "local only"

[Luna2308]

Hi,
I will try to explain my problem that I have a bit better.
I have a Toshiba laptop, 32bit Vista Home Premium.
I have had an internet connection through modem for a while, everything is good. Now I bought a Linksys WRT54G router, to be able to use the laptop with wireless. Did the setup, all was good, then suddenly no more connection.
Tried to reset the modem, the router and restart the laptop, got a connection again, but it went after 5-10 minutes, just simply stopped working. I still am connected, but it says "local only" and once "limited connectivity".
When I then connect the laptop directly to the modem with a cable, I have internet.
So the router seems fine, modem obviously, too.
What could be the problem that it always says "local only" all of a sudden, although I know there is internet???
Thanks for your help...

Make sure the cable from the modem to the router is pluged into the port labled "internet" not one of the other 4.
Unplug the modem and router for a minute, shutdown ur laptop then first replugin the modem, then router, and laptop last.

If the doesnt work... find an icon in your startbar next to the time that looks like cell phone signal bars. Right click it and select repair.
Hopefully it helps.
