I can see I have a wifi connection, but I can't get to the internet.
Just because you have wifi, doesn't mean you have internet. Wifi only carries the Local Area Network connection.
Here's a quick way to tell.
1. If you have a Windows machine open a CMD prompt (search CMD, then open). Try the command PING 8.8.8.8. If you get Replies then you have an internet connection. If you get request timed-out, then the while you may have a network signal, but it's not getting an Internet connection.
2. Next check for DNS - Try the command PING yahoo.com - If you see replies, then you have DNS . However, if you see something else like "could not resolve" or "requests timed out". DNS may be the issue. You'll need to work with a support person to get your DNS straightened out.
