HP Deskjet 3636 Printer Offline
Make sure your router’s connection remains active and stable if connected wirelessly. Contact your ISP if there is an HP Deskjet 3636 troubleshooting issue. Make sure the router is placed close to your 123.hp.com/dj3636 printer and computer. Check if many devices are linked to the same router. If so, detach them; this minimizes the Wi-Fi channel interference. Disconnect any USB or Ethernet cables if connected wirelessly. This may cause network issues. Open the HP printer software on your system and print an information page to ascertain that the network issues are resolved.
