You guys trying to get free net by trying swopping and changing with diffrent ip's of mtn or cellc/virgin? Try this quick. Go to start then type cmd at run. Type ping any ip of a site. You will see no failure and it pinged sucessfully. Try dnslookup mtn.net or other domains. Try manual adding the dns and see if you get one that resolves the host name for you and let you hook up on internet free
