Vista is not seeing my DI 624 DLink router

[dpbuettner]

I have went through hours of Tech support with Dell and Charter Communication. I am running two desktop computers. Dell 8100 Dimension running XP and a new Dell xps 420 with Vista Premium. The xps 420 won't recognize my DI 624 router. If I bypass the router I can connect to the internet. I have searched everything I can think of on the internet. I checked out the Dlink website and it told me the router should work with Vista.
One other thing ,I had to turn off VIsta firewall just to get connected to the internet. Can someone help.

I suppose you are now connected to the internet by LAN.

Try again to connect by Wifi:

BEFORE MAKE SURE THERE IS NO MAC FILTERING ENABELED IN THE ROUTER: YOU CAN SEE THIS BY PHYSICALLY CONNECT A PC TO THE ROUTER AND OPEN YOU'RE INTERNET EXPLORER AND GO TO 192.168.1.1 (OR SOMETHING LIKE THIS, CHECK YOUR MANUAL) AND ENTER THE SETUP PAGE OF YOUR ROUTER.

1)
Make sure your connection type in "Network Center" is set to private otherwise you won't be able to see other computers, printers or routers in your network.

2)
Make sure your windows firewall isn't blocking anything, you maybe can turn it off for a while.

3)
Make sure other installed firewall(s) are trusting the network completely. I'm using Norton: I had to set it to trust the network completely, otherwise there's no way to connect or even to see the wifi- router.

Hope it works for you...
