Ahh...university network. Some network management/user management devices do some things that look like an arp cache poisoning attack (because they are), that may be what you are seeing. Or, some of your fellow students may be attempting something. You really need to talk to your network admins - give them a list of IP addresses associated with the attacks, they can tell what those IPs are associated with.
When you loose Internet access, do you loose access to the local LAN too? When you do, what does the arp cache on your machine look like ("arp -a")?
Here is the Troubleshooting report of the lastest disconnect, hope it helps somehow.
