Printer Will Not Connect To Wi-Fi? Start With The Network

Reinstalling the driver a fourth time will not help if the printer never joined the network. Most wireless printer faults are really network faults.

Why the printer cannot see a network that is clearly there

Almost every home and small-office printer connects on 2.4GHz only. Plenty of modern routers broadcast both bands under a single network name, so when the printer looks for that name and gets steered to a 5GHz radio it cannot use, it simply never joins — and the error you see on the computer is a vague "printer offline". The other common version is a printer that worked for two years and stopped the week the router was replaced, because it is still holding an address from a network that no longer exists.

This one is rarely urgent, but it is the fault people waste the most time on. The driver gets removed and reinstalled, the printer gets factory reset, and none of it touches the actual problem, which is one layer down in the network. Knowing which layer has failed turns an afternoon into ten minutes.

Need help right now? Our Printer Support engineers can come directly to your home or office anywhere in Greater London to diagnose and fix this for you.

Print the network configuration page from the printer’s own menu. If it has no IP address, it never joined — nothing on the computer will fix that.
Check whether your Wi-Fi uses one name for both bands, or is 5GHz only. Either will stop most printers connecting.
Think back to whether it stopped after a new router, a new provider or a network name change. That is almost always the cause.
Make sure the computer is on the same network, not a guest network or a VPN, which hide the printer completely.

Separating a driver fault from a network fault

The quickest way through this is to prove which half is broken — the connection or the driver — before changing anything on either side.

Give the printer a fixed address by DHCP reservation so it stops moving every time the router restarts.
Check whether band steering is blocking the join, and connect it to the 2.4GHz radio explicitly if so.
Print once over USB to separate a driver problem from a connection problem, which are fixed in completely different places.
Confirm AirPrint or IPP discovery is enabled and that firewall or security software is not blocking it on the computer.

Setting it up so it stays connected

A wireless printer that is set up properly should not need touching again for years.

Reserve the printer’s address on the router so it keeps the same one for good.
Keep the network name and password when you change routers, and most devices will simply carry on.
Apply printer firmware updates while it is working, not while you are trying to fix it.
