I'm have some issues while connected to the network on campus only. From
the moment I get connected to the wifi, bwm-ng is reporting I'm receiving
nearly 50KB/s of traffic. I don't have a browsers open etc. Looking at
tcpdump, I see a lot of this.
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

With all this activity I can barely ssh to a machine, let alone surf the
web. I look around at classmates who are running something other than *nix
and they are all surfing away just fine.
I don't know a whole lot about networking, which leaves me with not much
of an idea on where to start on all of this. Any help would be really
appreaciated.
