Can't connect/Tried everything; Help please! :]

Hiya. So, xbox live works great at my house. Worked great at my buddies house. Now I'm back at my buddies house and the wireless adapter will connect to the internet, but not xbox live. It's not an MTU issue as it's worked here before, but I'm getting this error code everytime. I've browsed the internet as to what it is, but no idea's. I'll paypal someone 20 dollers to help me out; as customer service via phone was just annoying and unhelpful.
Error code =
W: 0000-0021
