I've checked the status of your service and your modem shows connected and has an internet access for more than 2 days now.
Were you able to check if you are connecting to the correct Wi-Fi? Is housemate's mobile phone connected to the home Wi-Fi or is using mobile data? Are you able to perhaps ask how is he/she able to connect the device(s)?
Please try to connect your devices using the Wi-Fi details indicated on the sticker at the back of the modem.
