Make sure your router’s connection remains active and stable if linked via a wireless network. If not, get in touch with your internet service provider. The router needs to be placed close to your printer and computer. You need to check whether many devices are linked to the same router. If so, detach them. This will minimize Wi-Fi channel interference. Detach any USB or Ethernet cables when connected wirelessly as this can cause network interference. A Network Configuration Page gets printed; this confirms the connection.
