Hi I have a Linksys WRT54G router with Comcast provrider. And everytime I test my Xbox Live 360 connection. It confirms my IP adress but when it gets to DNS it fails. I dont understand why because I can access the internet on my computer. And whats wierd is a month ago my Live 360 was working with no problems. And now I cant access Xbox Live. Is there a way to configure my DNS? Xbox Live was working a month ago for me and now its not.
