Printers are often the last devices to forgive a router change. Phones and laptops ask for the new password. Printers tend to sit quietly trying old details.
If the printer stopped after new broadband kit, start with router and Wi-Fi setup before assuming printer failure.
Router-printer checks
Run through the safe checks before you spend money, reset devices or start changing settings you may need later.
- Check whether the Wi-Fi name or password changed.
- Find whether the printer needs 2.4GHz Wi-Fi.
- Run the printer's wireless setup mode again.
- Print a network status page if available.
- Restart router, printer and laptop once.
Search intent
What this guide is designed to answer
People searching for "printer not connecting to router" usually need the printer working today, not a theory about printers.
This is based on the printer faults that turn up after new routers, Windows updates, replacement laptops and mixed phone/laptop setups in Ayrshire homes and small offices.
Ayrshire-specific context
Across Ayr, Prestwick, Troon, Irvine, Kilmarnock, Saltcoats, Cumnock, Largs and the villages between them, printer faults often happen after a new Sky, BT, EE, Vodafone, TalkTalk, Plusnet or Virgin Media router arrives. The printer is not always broken; it may simply be on the wrong network path.
What the symptoms usually mean
The printer works from a phone but not the computer
Usually points to
The printer is on the network, so the problem is usually Windows/macOS driver, queue, default printer or discovery.
Best next step
Clear the queue, remove duplicate printers, reinstall using the correct driver, and confirm the computer is on the same Wi-Fi.
Printing broke after a new router
Usually points to
The printer still remembers the old Wi-Fi name, old password or old IP address.
Best next step
Reconnect the printer to the new Wi-Fi from its panel or app before reinstalling it on laptops.
The printer says offline even when it is on
Usually points to
Windows may be pointing at an old queue, WSD port, stale IP address or paused print spooler.
Best next step
Do not keep adding duplicates. Identify the real printer connection and rebuild one clean queue.
How to get the best outcome
- Find out whether the printer is connected by USB, Wi-Fi Direct, the home Wi-Fi network, or a shared computer.
- Avoid adding the same printer repeatedly; duplicate queues are a common reason jobs disappear or stay stuck.
- After a router change, reconnect the printer to Wi-Fi first, then reinstall it on the laptop or desktop.
- If the printer is needed for work, keep one clean connection route instead of mixing USB, old Wi-Fi and mobile apps.

Old Wi-Fi details are the common cause
When you upgrade your home broadband or switch providers (e.g. to BT, Sky, Virgin, or Vodafone), your new router will broadcast a new Wi-Fi network name (SSID) and security password.
Unlike smartphones or laptops that prompt you to type in the new password automatically, printers frequently hang on to old network configurations indefinitely. Until you clear the cached credentials using the printer's control panel or manufacturer setup utility (such as HP Smart, Epson iPrint, or Canon PRINT), the printer will remain isolated.
To reset the connection, navigate to the printer's Wireless Settings menu, select 'Restore Network Defaults' or 'Run Wireless Setup Wizard', and select your new network name.
2.4GHz frequency compatibility
Most home Wi-Fi printers operate exclusively on the 2.4GHz wireless frequency band. Modern Wi-Fi 6 and smart mesh routers often combine 2.4GHz and 5GHz into a single network name, which can prevent older printers from completing the initial handshake.
If your printer refuses to connect or repeatedly fails setup, log into your router's admin panel and temporarily separate the 2.4GHz and 5GHz bands or enable a 'Guest 2.4GHz' network specifically for smart home devices and printers.
Alternatively, if your router features a WPS (Wi-Fi Protected Setup) button, press WPS on the router, then trigger WPS mode on your printer within two minutes to pair them automatically without typing passwords.
Reconnect every laptop and PC after the router fix
Getting the printer connected to the new router is only half the battle. Your laptops and desktop PCs must also rediscover the printer on its new local IP address.
On Windows 10/11, go to Settings > Bluetooth & Devices > Printers & Scanners. If your printer shows as 'Offline', click 'Remove Device', then click 'Add Device' to let Windows search the new router subnet and re-install the correct print queue.
On macOS, open System Settings > Printers & Scanners, delete the old printer entry, and re-add it using AirPrint or Bonjour network discovery.
Do not replace a printer just because Wi-Fi changed
A router change can make a working printer look broken. Reconnect and test before deciding it is dead.
Quick questions
Why will my printer not join the new router?
It may have old Wi-Fi details, need 2.4GHz, or require setup mode to be run again.
Can you reconnect printers after broadband changes?
Yes. This is one of the most common printer and router jobs.
Will my laptop need set up again too?
Often, yes. Once the printer is on Wi-Fi, the laptop may still need the correct driver or printer entry.
