okay, this has bugged me for weeks now. I posted this before to mint forums but I post here, in case someone here would have a fix.
My problem is, that in my dorm room, internet is slow, or not slow, but it sometimes goes the speed it should (between 60 - 100 megas/s) but then, suddenly it slows down under to 1 mega/s. Most of the time, it is under 1. This problem is only on my computer, and only in my dorm room. IT person has tried reseting the router here but it wont work, but this problem appears nowhere else. Not back in my home, not at my uncles/aunts place.
here is info on my connection:

here is all the information on the situation. As stated before, this happens ONLY at my dorm room and ONLY to me. It affects firefox, IRC and MSN Messenger (phone bill shot through the roof because this, I have to keep contact to my girlfriend somehow. . .)
if anyone has _ANY_ idea what this is about, I would appreciate it. . .
