Lnet – LOAS's network for students

Lnet is a student network that Lappeenranta Student Housing Foundation (LOAS) offers to students living in its apartments. The network can be accessed from nearly all LOAS residences in Lappeenranta, including all apartments near the Lappeenranta University of Technology (LUT) and Saimaa University of Applied Sciences (Saimia) in Skinnarila.

This means that the network is used by LOAS residents (mostly students of LUT and Saimia). Lnet provides 24-hour Internet access to the residents mainly for study purposes.
