Canon PIXMA TS3720 offline or not connecting to Wi-Fi? Check the network first.

For a Canon PIXMA TS3720 that appears Offline or cannot be found on Wi-Fi, confirm whether the printer itself is still joined to the intended network. If it is, focus on discovery and the saved printer queue before resetting wireless settings.

Direct answer

What this usually means

If the TS3720 is Offline, first distinguish a printer-to-router failure from a computer-to-printer discovery or queue failure.

Most likely causes

  • Printer and computer are on different or isolated networks
  • Router name or password changed
  • The printer received a new IP address
  • A stale queue still points at an old network path

Safe fix order

  1. Check the printer wireless/network status without resetting it.
  2. Confirm the computer or phone and printer use the same normal LAN, not guest Wi-Fi.
  3. Print or view the printer network report when the model supports it and note the current address.
  4. Restart the printer and client device before changing router settings.
  5. Use the exact manufacturer setup workflow if the printer must be rejoined to Wi-Fi.

Model-specific context

Why the PIXMA TS3720 path matters

Canon provides TS3720 setup instructions, manuals and operating-system-specific downloads on its U.S. support page.

Do not assume instructions for a similarly named model are interchangeable. Confirm the full model before drivers, firmware, supplies or resets.

OS / connection context

Wi-Fi / network

This page targets offline or Wi-Fi on Wi-Fi / network. The printer itself should be checked for a physical or consumable alert before software changes are made.
