Long story short:
I had my Laptop hooked to my xbox 360 through ethernet/cat 5 cable to get on live. I discover my internet was being stolen, I set up WAP key. I had to reconfigure my laptop (Basically, searched for router so I could introduce key) Worked. Have internet, but my 360 wont work, apparently it is geting wrong IPaddress:
Subnet Mask: 255.255.255.0
No default gateway and it says manually config.?
I've tried releasing and renewing ip, nothing. Any ideas?
