Do you have Fixed Internet from us and the connection is not working properly? If you suspect that your modem is not working as it should, a factory reset (in other words, a hard reset) can help. Before you do this, we recommend to use the network status checker (CZ) and restart the modem. For more technical troubleshooting tips, see this section of the Care Center.
Performing a reset will erase all modifications to the modem settings and reset them to the factory defaults. Most often, this will mean that your Wi-Fi network name and password, or your administration password, will match the information you find on the label on your modem. You can also refer to your modem's manual for the specific reset procedure.
It's usually on the back of the modem and is recessed, so you'll need a paperclip or maybe a toothpick to press it.
The modem must be powered on before pressing the reset button.
This will set the default Wi-Fi network name, default passwords, etc. You can find this information on the modem's label. If you have DSL or Optical Fixed Internet and you are not using a modem from us, you may need to set it up again for it to work properly on our network (CZ).
In the case of a Wi-Fi connection, you will need to search for the network using the label on the modem, the username and password will be set to the default values.
