Network Bridge Problems.

My House network is very intricate, but now I'm starting to run into some problems. This is my network

The Router Downstairs is sending wireless N signals to my computer.

Then Using Vista, I bridged the connection to my wired router.

Then connected to the router is my 360 PS3, and my computer is sharing the internet connection with the bridge.


So Here's my Problem....

On the back of my router there is 5 ethernet ports. One that says internet, and then 1234. I used to connect my computer with the one that say's internet. When I did this, the internet worked fine on my consoles, but the file sharing didn't work.

So then I connected it to the "1" port. and the internet worked and the file sharing worked!!!

Then.. the next time I start my computer, It's thinking that the router is the main internet source, and not the wireless N.
I have to unplug it. wait 2 min and plug back in to work. Is there a way to make the bridge default to my Wireless, instead of the wired router??

Thank you!
