Vista - wireless network OK, but no internet on Vista laptop

I have a problem with my new vista home premium laptop. The internet worked for 2 days when I first bought the thing (5 days ago or so), but for the past two days, no dice.

I have a netgear wireless router. My work laptop (xp) is on the same wireless network and working fine.

The vista laptop does get onto the wireless intra net (prints to wireless network and access to wireless NAS device works).

IP config on the vista shows

IP as 192.168.1.4(Preferred) and the DHCP and DNS server as 192.168.1.1 which is the router. this is the same output as the ipconfig on the xp machine which is working (except the ip is 192.168.1.5) My desktop is directly attached to the router (.2) the NAS is .230 and the print server is .105 so my network is a little crowded, but I dont understand why it wont access the internet with the new Vista machine.

I can even ping google.com and yahoo.com from the vista laptop... but I cannot get firefox or internet explorer to get into the internet. Chat software also fails to function.

Any ideas?

I can ping the the router and other computers on the network too. Basically intranet works, can ping external web sites (DNS must work) but no browsing...

thanks again for any help

does the WIRED connection work or not? if you have the same issue,
I'd start looking for malware.

did you change the default SSID name? what kind of security are you
using? (WPA2 is best).

I am using a descriptive ssid for our family and WEP protection. My wireless router is pretty old so I am not sure if I can use WPA2. The computer worked for the first few days of its existence at my house, so I am sure it <i>can</i> work.

I havent tried the wired connection yet. I will do that and report back.

thanks for the initial comments, but I would be surprised if it was malware, but I will follow up with that too.

So when I plugged into the router the ethernet card said "Network Cable Unplugged" When I plugged in the cable it would flash enabled for a second then go back. The router never lit up as a connection. If i plugged the laptop directly into the output from my cable modem I got an IP address, but no DNS address and no browsing.

have you power cycled the router and the computer?

when you plug the laptop directly in to the cable modem, do you
power cycle the cable modem?

I did some updates on the McAffee virus software and mysteriously it all works again... not sure what was wrong, I hate problems that are "fixed" but no clear path to the solution... oh well, on with life. Thanks so much for your help Barb!!

glad it was resolved for you.

good morning...thanks for all your posts and information - I am having the same EXACT issues that you experienced and was wondering if you honed in on the issue yet? I had 1 day of wireless then AT&T yahoo crapped out on me, then nothing. I thought it might be McAfee as well but have not figured it out yet...online wired now.
Thanks again, glad to know that I am not a total idiot that cannot figure out a wireless router set up!
