How Do I Reconfigure My DSL Router?

A DSL router can be a security risk because an (ex-)partner may be able to access devices on your Wi-Fi network, for example through apps connected to your router. If your (ex-)partner has moved out, the router should therefore be set up again from scratch.

Step by Step

Make sure you have the contract documents from your phone/DSL provider, including your contract number, access ID, and password.
Search online for your specific DSL router model, or ask us for help.
Save or print the instructions first, because you will not have DSL or Wi-Fi access while setting up the router.
Reset the DSL router to factory settings. This means restoring it to the state it was in when it left the factory.
Set it up again using your own access credentials.
Choose a secure password for the router itself and for your Wi-Fi. See also: What are Secure Passwords and How Do I manage Them?
Set up a guest Wi-Fi network. Most routers offer this functionality.
