LMAO. I'd try disabling your wireless link. Make sure it's not partially connected, then shut it down via software--should be able to do that from the systray. Then disconnect it physically, if you can. Wait a few seconds, plug it back in. If the system doesn't automatically recognize it as being present, you may need to go back to your software connection and try to re-establish a link.
If that doesn't work, you can try the same thing from your source, which I'm guessing is a desktop computer. Especially since you seem to be able to post here.
Before you do all of that, however, I'd check to see if your internet connection is even alive. Could be an outage, and if you have a wired connection, easy to check.
If nothing else works, then yeah, a brick.
