Wireless Home Network - laptop is connected to network, but not to Internet. DNS missing.

I guess my question title says it all. I have a home office netowrk with a desktop & 2 laptops.  Linkysys G wireless Broadband router and DSL model. All 3 connect properly for file access. Desktop and laptop 1 access Internet just fine. Laptop 2 doesn't access internet. Checkied wireless connection and it says it's connected.  Help would be most appreciated. New to the exchange. This is probably and easy thing for those in the know, thus the low point assignment; but in truth, it's a big difficult problem for me not to have access! Thanks in advance.

In Internet Explorer:
Tools -> Internet Options -> Connections -> LAN Settings ->
Make sure "Automatically detect settings" has a check.
Make sure "Use a proxy server" has no check.
Then restart IE

Still not working? Read the manual to see if the router settings are too restrictive (e.g. maybe it's only set to allow 2 connections):

Go to www.lynksys.com --> Support --> Downloads  & download the router manual.
The manual will say to type 4 numbers, e.g. 192.168.1.1, into your browser to get into your router setup
Will also tell you the default username and password (usu. admin for password & the same or nothing for username)

Thanks so much for the responses. "automatically detect" was not selected. It is now and I'm back up and running. And thrilled!
