Why is the network slow?

There are many answers to this question, and the answer can change in different circumstances. One possibility is that a large majority of the Oberlin population is trying to use the network at the same time you are, so everyone is fighting for our bandwidth.

Another possibility is remote congestion. The site you are trying to access may be at the limits of its own bandwidth, and therefore not able to talk to Oberlin quickly even though we have plenty of bandwidth locally.

If you are using wireless it's important to understand that speeds may go up and down very dramatically, even if you remain stationary; this is the nature of a wireless connection. Receiving a wireless signal is very similar to receiving a radio station, in that it is affected to a greater or lesser degree by everything in the path between you and the base station.

Why isn't the network port in my room working?

Residence hall rooms on campus have wired network ports but these ports are not active by default.

To request that a network port be activated in your room, contact Please be sure to include your building, room number, and the number printed on your network port (if applicable). We also require a phone number so our staff can contact you to set up a time to activate and test your port.

Why doesn't my online game work?

While we try and make sure that online gaming does work, especially from Resnet, many games use many different methods of connection to the internet and our packet shaper may not yet be aware of your game. Sending detailed information to (what port, TCP or UDP, are you connecting to a specific server) can assist us in making gaming work for you. More here.

Are we blocking port xxx?

Maybe. If you need another port open for some reason, send a request to and CIT will consider those requests on an individual basis.
