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.

Notes

Using routers in Lnet

2017-02-17

As a reminder: When using home routers or wireless access points, take care to check the connections. The port meant for your Internet connection (in this case Lnet), is usually marked either "Internet" or "WAN", with ports meant for your devices marked "LAN".

Plugging LAN ports to Lnet will cause problems for other network users, and connections with misconfigured or misconnected devices will be disabled without warning.

ADSL modems without a capability of using a regular Ethernet connection as uplink cannot be used in Lnet at all. Connections with misconfigured ADSL modems will also be disabled.
