Printer Won't Connect to Wi-Fi After Router Change

📅 11 July 2026 ⏱ 4 min read 🔧 PC Repair

You've just had a new router fitted — maybe Movistar swapped your box, or you upgraded to a better one — and now your printer refuses to work. It was fine yesterday. Nothing has physically changed. Yet here you are, staring at a flashing Wi-Fi symbol on the printer and a queue of documents going nowhere. You're not alone; this is one of the most common calls we get here on the Costa Blanca.

The good news is that in most cases you can sort this yourself in under 15 minutes. Let's walk through it.

Why Does a Router Change Break Your Printer?

Your printer doesn't connect to "the internet" in a vague sense — it connects to a specific Wi-Fi network by name (SSID) and password. When a new router arrives, even from the same provider, it usually brings a new network name and/or a new password. Your printer still remembers the old details and keeps trying to find a network that no longer exists.

There are two other common culprits worth knowing about:

Step-by-Step Fix

1. Gather your new Wi-Fi details first

Find your router's network name and password — usually printed on a sticker on the side or bottom of the router. In Spain, providers like Movistar, Vodafone, and Orange all put it there. Write it down. Double-check whether there are two networks (e.g. "MyHome" and "MyHome_5G") — use the one without "5G" in the name for your printer.

2. Reset the printer's wireless settings

You need to clear the old network from the printer's memory. The exact steps vary by brand, but on most printers:

If your printer has no screen, check the manual or the manufacturer's website — most have a "wireless reset" button combination.

3. Run the Wi-Fi setup wizard

Once cleared, follow the printer's built-in Wi-Fi wizard. It will scan for networks, show you a list, and ask for your password. Select the 2.4 GHz network and type the password carefully — these are case-sensitive and a capital letter in the wrong place is the number-one reason people fail here.

4. Print a network configuration page

Most printers let you print a test page that shows the current IP address and whether it's connected. On HP this is often under Settings → Reports → Network Config. If it shows an IP address starting with 192.168.x.x, you're connected. If it shows 169.x.x.x, it hasn't connected properly yet — go back to step 2.

5. Update the printer port on your PC (Windows)

Even after the printer reconnects to Wi-Fi, Windows may still be pointing at the printer's old IP address. To fix this:

  1. Open Settings → Bluetooth & devices → Printers & scanners.
  2. Select your printer → Printer properties → Ports tab.
  3. If the IP address listed doesn't match the new one on the config page, click Add Port, choose Standard TCP/IP Port, and enter the new address.

On a Mac, simply delete the printer from System Settings → Printers & Scanners and add it again — macOS will find it automatically on the local network.

6. Still not working? Try WPS

Some routers have a WPS button (usually labelled WPS or with a padlock icon). Press it, then within two minutes press the WPS button on your printer (if it has one). They'll shake hands automatically without you needing to type a password. Note: some Spanish ISP-provided routers have WPS disabled by default for security reasons — check the router's admin page if you're not sure.

What If None of This Works?

If you've been through every step and the printer still won't connect, it's usually one of three things: a faulty wireless card inside the printer, a router setting blocking unknown devices (MAC address filtering), or a corrupted driver on your PC. These are worth a quick look before you consider replacing anything — a 10-year-old printer with a dead Wi-Fi chip can often still be used via USB while we source options.

If your machine is also running slowly or throwing up other errors at the same time, it may be worth a broader check-up — see our guide on 5 warning signs your laptop needs a repair for things to look out for.

FAQ

Why does my printer keep disconnecting from Wi-Fi?

The most common causes are an IP address that changes each time the router restarts (fix this by assigning a static IP in the router's admin panel), a weak Wi-Fi signal where the printer is located, or outdated printer firmware. Try moving the printer closer to the router temporarily to test whether signal strength is the issue.

My printer connects to Wi-Fi but the computer still can't print — why?

This usually means your PC is still pointing at the printer's old IP address. Go to Printers & Scanners in Windows Settings, open Printer properties, check the Ports tab, and update the IP address to match the current one shown on the printer's network config page.

Can I connect a Wi-Fi printer using a USB cable instead?

Yes, absolutely — and it's often the quickest short-term fix while you sort the wireless side. Simply plug in the USB cable, Windows will install or reuse the driver, and you'll be printing within minutes. It won't fix the Wi-Fi issue, but it unblocks you.

Does changing to a new router in Spain void my printer warranty?

No. Reconfiguring your printer's Wi-Fi settings is normal use and has no effect on the manufacturer's warranty. If the printer's wireless card fails through no fault of your own, that's a hardware defect covered under standard EU consumer rights (2-year minimum).
