Vista - Cannot go on the internet but can see other computers on my network

I recently got a new computer with Vista Home Premium 32 bit. The main problem is I can't go on the internet but when I am browsing my network I can see my other computers shared folders.
Every computers are connected through my Linksys wrt54g v.5 wireless router and all of them, except for my new one, can go on the internet.(I have 2 desktops, one running with win98 and the other with winXP and they are connected directly with cables on my router. Also, I have a laptop with winXP using the router wireless.)

Here are my ipconfig/all:

Any help would be really appreciated !

(Also, I updated my router firmware and my network card...but no luck...I guess that might be a compatibilty issue between vista, my realtek network card and my router...
And I try pinging some websites like google.ca through command prompt, and I can have a ping...but yet I cannot see them with IE7... )

Does the firmware on your router support Vista? Also, I spent 30 minutes
trying to get to the Internet with a new laptop before I realized I had
turned on MAC filtering in the router. Just a thought.

Yup, on the LinkSys website, it says that the wrt54g router is compatible with vista .
And for the mac filtering, in my router page it has an option to enable wireless mac filter. But, since my new pc is directly connected to the router, that didn't work.

The Linksys wrt54g has been around a long time and does work with Vista. I
was asking about the firmware on the router. If you recently purchased your
router you are probably OK. If you have had the router for a year or so then
I would check your version of firmware to see how out of date it is.
