Router
If you want to use multiple devices or just have WiFi, you have to get a router. The following tables list a few devices which have successfully worked in our network, although this list may not be complete.
Security advice#
The TP-Link setup domains "tplinklogin dot net" and "tplinkextender dot net" are not correct anymore and may distribute malware.
We strongly recommend to change the default password of your WiFi. There are easy ways to determine the default passwords from the network's name and/or MAC-address for several devices.

Retrieve MAC address#
In order for the router to be operated in our network, the WAN MAC address of the router must be registered on our website. This can usually be seen in the configuration interface of the router.
Important: The MAC address on the back of the router is usually NOT the WAN MAC address.
