A wireless printer remembers the network information used during setup. After a router, internet provider, Wi-Fi name, or password changes, phones and computers may reconnect while the printer remains on the old network. Restore the printer's network connection first, then check each device that needs to print.
Confirm what changed and where the connection stops
Write down whether the router, internet provider, Wi-Fi name, password, extender, or mesh system changed. Check the printer's wireless light or network screen and, if the model offers one, print a network or wireless status report.
Make sure the computer or phone is connected to the intended home or office network rather than cellular data, a guest network, or an old extender name. Other devices reaching the internet do not show that the printer joined the same network.

- The printer brand, model, and wireless status
- Whether no device can print or only one device is affected
- Any message shown by the printer, computer, or setup app
Reconnect the printer before reinstalling it
Use the instructions for the exact printer model to connect it to the new Wi-Fi. Depending on the model, that may use the printer's screen, buttons, a temporary setup mode, a cable, or the manufacturer's official app.
Download setup software only from the printer manufacturer, Microsoft, Apple, or an official app store. Avoid changing several router settings or factory-resetting the router just to make the printer appear; that can disconnect other devices and erase useful network settings.
Add or test the printer on one device at a time
After the printer shows that it is on the intended network, try one small test page from one computer or phone. If an old printer entry still points to the previous connection, the device may need the printer added again through its normal printer settings.
Confirm printing before testing scanning, because scanning may use a separate app or setup. If one device works and another does not, leave the working connection alone and focus on the device that still has the old printer or queue.
Separate a printer problem from a network problem
If every device has trouble getting online, begin with the router or internet provider. If the printer cannot join the new Wi-Fi, check the exact model's network requirements and official setup instructions. Compatibility and setup methods vary by printer.
If the printer is connected but shows a paper, ink, toner, cover, jam, or mechanical error, the router change may not be the cause. Grinding, broken internal parts, leaks, or repeated paper jams may need the manufacturer or a printer repair specialist.
