There are 3 laptops in a wireless home network.  Two operate with no problems.  Another will connect with the router with good signal strenth, but will no connect to the Internet.  Security and privacy are set a medium.  Can someone suggest possible options to solve the problem.

Thanks

If your little router is handing out DHCP addresses, please make sure that the unit that can't hit the internet isn't set as a static IP.

Can you provide the screen shot?

Maybe you have static IP assigned on the wireless card that is used for another network else where?

try to ping ..

1-start -> run -> cmd
2-ping 8.8.8.8
3- if message said request time out , possible that wrong IP configuration , maybe set to static IP , if there is static IP remove it , but if the message was "destination host is unreachable" , then the problem with IP , its did not get IP from router , try to check DHCP Client services by going to start then run then services.msc , if its work , possible something wrong either with NIC or wireless password.
if its reply .. then its ok , try ..
ping google.com ..
if its failed possible its DNS problem.

like others said , if you provide screen shot , we will get information

If you are able to ping ok but can't load webpages one thing you can try is going to:

 Control Panel > Internet Options > Connections Tab > LAN Settings

1. Make sure "Use a proxy server..." is not checked
2. Check "Automatically detect settings"

Try to disable security on your wireless network and make it Open, then try to connect that laptop. if it is connected to internet then the problem is that the wireless adapter on that laptop is not compatible with the settings on your wireless device, try to use WEP key on your wireless network and tell us the result.

I apologize for the lack or activity.  The suggestions sound like good ones; I just haven't had the chance to try it out.  Hopefully I can get that done in the next couple of days.  Again, thanks for the patience.

I'm back - finally.  I checked the IP and DNS settings and they are all set to automatically get IP and DNS, as are the other laptops that successfully connect.  However, I have been able to successfully connect to 2 other wireless networks, one secure and one unsecure.  With the problem network, the diagram shows the computer - then the network - then the Internet.  Between the network and the Internet is a red X.  It seems to have a good connection to the network/router, but not on to the Internet.  It's perplexing that other computers connect OK.  Any further suggestions?  If a screen shot would help, what view should I provide?

ok , check the DNS , try to set manual DNS to 8.8.8.8 which is google dns , disable it and re-enable if its work fine there is problem with your DNS server that you currently use.

I will try the manual DNS.  I also suspect it may be something in the setup of the AT&T box which appears to be a combined modem and router (it's at my cousins, so I don't have ready access to it).  I hope to be able to work it Tue evening.

its possible that problem with router , this shown clearly if you tried to ping from the rounter itself , in management of AT&T box should have ping option , try ping 8.8.8.8 , if ts not work then its clear that problem with connectivity of router ,if its work you need to check if there is firewall working on the router , then try to stop firewall on your PC...

The driver update indicated that the current version was the best available.  My next step is to try AT&T tech support.  I'll report the result.

After an hour on the phone with AT&T tech support, they could not solve the problem and referred me to a higher level of tech support.  At the point I referred further action to my cousin who has the issue.  I am clsing this question and will distribute some points to those who provided suggestions.  Thanks much for trying.

While the problem was not solved, it is likely an issue with the modem-router that AT&T will have to address.
