Why won't my device connect to NBN WiFi?

The most common reasons a device won't connect to WiFi are: entering the wrong password (it's case-sensitive), the device having a saved incorrect password, MAC address filtering being enabled on the modem, or the modem needing a restart. Try forgetting the network and reconnecting with the password from the sticker on the modem.

What is the best way to improve NBN WiFi coverage in a large home?

A mesh WiFi system is the most effective solution for large homes or homes with thick walls. Mesh systems use multiple nodes placed around the home to create seamless coverage. Good options available in Australia include the TP-Link Deco XE75 and Amazon eero Pro 7, both available at JB Hi-Fi and Officeworks.

Q: Why is my NBN WiFi signal weak in some rooms?
