I got a WRT54G today for wireless networking in the dorms. I set it up and enabled WPA security but for some reason the wireless is sluggishly slow or doesn't work at all on my Macbook. I tested out on my friend's Dell laptop and it did not work either. The funny thing is, it works perfectly with good speeds on my iPhone without any problems whatsoever. I still have yet to try this on my PS3 and Wii. Under an ethernet hookup my Macbook will work perfectly. Any suggestions as to what I could be doing wrong? Is it a possibility that my school has restricted the internet connection here to only work via ethernet (if that's possible)? Sorry, I'm pretty new to this stuff.
