Symptoms
- Printer shows 'offline' or 'not connected' on the computer
- Print jobs sit in the queue and never print
- Printer's control panel shows no Wi-Fi signal or an error icon
- Printer worked before but stopped after a router or password change
Likely causes
- CommonRouter's network name or password changed since the printer was set upPrinters save their Wi-Fi credentials and don't update automatically when you change your network.
- CommonPrinter's Wi-Fi radio went to sleep or disconnected after inactivitySome printers drop Wi-Fi after periods of not being used and need a nudge to reconnect.
- PossiblePrinter too far from the router for a reliable signalPrinters often sit in a corner or closet with weaker Wi-Fi coverage.
- PossiblePrinter connected to the wrong band (5GHz) if it doesn't support itMany printers only support 2.4GHz Wi-Fi.
- PossibleComputer or phone using a stale printer driver connectionThe printer itself may be online, but the computer's saved connection to it is outdated.
What to do
- On the printer's control panel, check its Wi-Fi status; if disconnected, go into its network setup menu and reselect your Wi-Fi network with the current password.
- Make sure you're selecting the 2.4GHz network name if your router broadcasts two separate networks.
- Print a network configuration page from the printer's menu (most printers offer this) to see its current IP address and status.
- Restart the printer by turning it off, waiting 30 seconds, and turning it back on.
- Remove the printer from your computer's device list and re-add it, letting the computer search for it fresh on the network.
- Move the printer closer to the router temporarily to rule out a weak signal.
- Update the printer's firmware and your computer's printer driver from the manufacturer's website if reconnecting doesn't stick.
When to call a pro
Not usually needed; most printer Wi-Fi issues are solved by re-running setup on the printer itself.
