If the problem persists even after checking the above:
  • Turn off the devices, and then turn them on again.
  • Wait for a while, and try again to connect to the network.
2. Check whether the machine is turned ON.

3. Check the installation site of the machine and the wireless router.
  • Is the machine too far from the wireless router?
  • Are there any obstacles such as walls between the machine and the wireless router?
