Determining the MAC address of the network card

You can find out the MAC address of the network card in your computer by following the instructions.

Set up fixed network connection

Please connect your computer via LAN cable to the data socket. You will then have access to the Internet via your internet browser.

Using a router

It is possible to use routers. However, ZIM does not set up the devices.

A router in the dormitory must have an Ethernet interface (10/100Mbit/s) towards the Internet (WAN) (no DSL connection).

Only the WAN or Internet connection (usually marked yellow or blue) may be connected to the dormitory's house network. The router must be operated in router mode.

Different modes can be selected for some models. The configuration of a router is always done via the website of the device (e.g.:

The "WAN Connection Type" (the connection to the Internet) must be set to "Dynamic IP".


Please provide the MAC address of the WAN (Internet) port of the router by e-mail to zim-serviceuni-potsdamde.

For the routers we specifically have tested, the MAC printed on the bottom of the device is not the address we can use. The last digit must be incremented by 1. For example, if there is a "5", then please enter a "6", if there is an "a", then please enter a "b".
