Netgear Router - Network works, internet doesn't

[Fisch]

I have a brand new Dell Inspiron laptop with Vista and a Netgear RangeMax Next Wireless Router (WNR834B). I have a network connection, but no internet. If I use an Ethernet cable to the Router, the internet connection is fine. Yesterday, I installed Netgear's Vista drivers and the internet worked - until I rebooted. Now it's gone again.

My brother has the same set-up (Dell & Netgear), but Windows XP. His is fine. He also tried my laptop with his network and it still didn't work with the internet connection - although his laptop/internet works perfectly.

We're assuming there's a setting within Vista that I have wrong, but we haven't found anything. Any suggestions would be greatly appreciated!!
Thanks.

Thanks for your quick reply!

We did double check that the router is compatible with Vista - at least, they say it is!

And I tried disabling the IPv6 this weekend - no luck.

I'll try the other tonight and post back. Thank you!

I tried your suggestions and they haven't worked. I then called Dell support and their 'solution' was to turn off my firewall. They told me I could turn on the Windows firewall, but leave off McAffee and it should work, but when I turned on Windows firewall again, it stopped working. If I have the firewall off, I connect to the internet just fine. With it turned on, I still connect to the network, but not the internet.

I thought I had read something before about security, but now can't find it...? Any thoughts? I can't believe Dell's solution was to turn off my security - and without telling me (they took control remotely). If I hadn't been watching them, I probably wouldn't have noticed the security was disabled! Crazy.

Normally, we don't recommend to use two Firewall or security software. Try this: turn off all firewall, Windows firewall and McAfee. Can you access the Internet? If yes, turn on only Windows firewall.
