There are a number of wireless access point in building Celestijnenlaan 200A.

These access points have both 802.11g (54Mbps à 2,4 Ghz and compatible with 802.11b) and 802.11a (54Mbps à 5GHz).

On these access points there are (at least) 3 wireless networks available: eduroam, kuleuven and kuleuven-guest.

These access points and wireless networks on them are implemented/maintained by central KU Leuven ICTS:

Connection instructions:

    • The exact authentication method varies according to the network, see below for details


  • clear text wireless or cabled network
