Wifi available while traveling, no internet. Help?
Even though this isn't one of my main priorities, whenever I travel from college from home, which is a good 10 hours, I try to use internet, and my macbook pro says there is wifi, but no internet. I usually take a greyhound or trailways bus back, which says there is wifi. I have seen it and it says on my laptop there is wifi, just no internet, and I don't know much about the wifi signal. Is there a certain way I can get it fixed so I can get my internet working? Anything will help. Thanks!
