I have been having problems with this i was wondering if someone could help. I cant seem to the crossover or the share to work properly. Also i cant fully access the shared option. Explained in picture below.

<working on this
The hardware i have is this:
1) xbox 360
2) Crossover cat 5 ethernet cable (not patch)
3) Dell pc
4) usb belkin wireless adaptor
5) belkin wireless router
Whenever i bridge connections my regular internet craps out. Also happens when i share. The lan looks like it connects but never shows the xbox's gateway number and the xbox can never find an ip or subet mask etc.
Any help will be greatly appreciated.
