I attend a University that has a universal wireless internet access lets call it University-Net. University-Net is accessible for all students as long as you can pick it up. Usually when you are outside waiting for class, or when in the Union, or even in many classes you can pick up the signal and hop on the web. The problem is in a few of my classes I am unable to get a signal and therefore can not connect to the internet. The reason for not being able to get signal is not because you are not allowed to receive it in the building its just that some classes are down stairs or buried deep behind walls where its hard to get reception I've seen on the internet a few devices to get better reception but most of them seem like junk (as well as not for legal purposes). In my case I'm not hijacking a signal illegally but rather I'm just picking up the University signal where its hard to get. Is there any sort of realistic peripheral I can add to my MacbookPro in order to get the Wi-Fi signal or will I have to just live with the fact I can't get it in some classes. I hope thats not the case and there is something to do. Thanks in advance for any advice I receive.
