If you are having problems with your internet connection, you should always first contact your dormitory network group. This group is responsible for the daily operation of the network equipment located at your dormitory.
If you get no response from your network group, then you can contact the K-Net operations group on drift at k-net dot dk.
When requesting support, always include as much information as possible! This means details about dorm, room, operating systems, if you are using a home router, if you are using dorm wireless (and your location) or not, IP-addresses involved(if any), etc. This will make it much much easier for us to help you.
If you yourself are in the network group, then you are welcome to access the operations wiki and contact the K-Net operations group on drift at k-net dot dk.
