Did your printer stop working right after you changed your router?
Maybe you upgraded to a faster WiFi plan.
Maybe your ISP replaced the router.
Maybe you reset it.
Now suddenly:
Your printer says offline.
It won’t connect to WiFi.
It’s not detected on your computer.
If you’re searching printer offline after router change, you’re not alone. This is one of the most common printer issues we see at Printer Offline Fix.
The good news?
Your printer is probably not broken.
It just needs to reconnect properly.
Let’s fix it step by step.
Why Printer Goes Offline After Router Change
When you replace or reset a router, several things change:
- WiFi network name (SSID)
- WiFi password
- IP address range
- Security protocol
- DHCP assignments
- Network frequency (2.4GHz vs 5GHz)
Your printer was connected to the old router settings.
Once the router changes, the printer loses communication with your network.
Your computer then shows:
Printer Offline.
It’s a network reconfiguration issue — not a hardware problem.
Most Common Causes After Router Change
Here’s what usually goes wrong:
1️⃣ Printer Still Connected to Old WiFi
Your printer may still be trying to connect to your old WiFi network.
If the SSID changed, it won’t reconnect automatically.
2️⃣ New Router Assigned Different IP Range
Old router IP range:
192.168.0.x
New router IP range:
192.168.1.x
If your printer was configured with static IP on the old range, it won’t communicate on the new network.
3️⃣ 5GHz vs 2.4GHz Conflict
Many printers only support 2.4GHz WiFi.
If your new router defaults to 5GHz only, your printer may fail to connect.
4️⃣ WSD Port Conflict
If your printer was installed using WSD port, Windows may lose track of it after network change.
5️⃣ Firewall or Security Settings
Some new routers enable stricter firewall settings that block printer discovery.
How to Fix Printer Offline After Router Change
Follow these steps in order.
Step 1: Reconnect Printer to New WiFi
On your printer control panel:
- Go to Network Settings
- Select Wireless Setup Wizard
- Choose your new WiFi network
- Enter new password
- Confirm connection
If your printer doesn’t reconnect automatically, this step is mandatory.
Step 2: Restart All Devices
After reconnecting:
- Turn off printer
- Restart router
- Restart computer
- Turn printer back on
This refreshes IP assignments.
Step 3: Check Printer IP Address
Print a network configuration page and confirm:
- Printer has valid IP address
- IP matches new router range
If printer shows 169.x.x.x IP, it failed to connect properly.
Reconnect again.
Step 4: Update Printer Port in Windows
This is a critical step most people miss.
After router change, your printer’s IP may change.
Windows may still be pointing to the old IP.
To fix:
- Open Control Panel
- Devices and Printers
- Right-click printer
- Printer Properties
- Ports tab
- Check selected port
If incorrect, add a new Standard TCP/IP port with updated IP.
Avoid WSD port for stability.
Step 5: Assign Static IP (Recommended)
After router change, dynamic IP reassignment becomes more common.
Assigning static IP prevents future issues.
Log into router:
- Go to DHCP reservation
- Assign permanent IP to printer
- Save settings
Static IP prevents printer offline errors after router restart.
Step 6: Reinstall Printer (If Needed)
If Windows still shows offline:
- Remove printer from Devices
- Add printer manually
- Choose “Add using TCP/IP address”
- Enter updated IP
Avoid automatic WSD detection.
Printer Not Connecting to New WiFi? Try This
If your printer won’t connect after router change:
- Enable 2.4GHz band
- Disable WPA3 temporarily (use WPA2)
- Move printer closer to router
- Reset printer network settings
Some older printers struggle with modern router security settings.
Printer Offline After Router Reset But Phone Prints?
If your printer works from your phone but not computer:
The printer is connected correctly.
Your computer configuration is outdated.
Update port settings on your computer.
Business Environment Fix
In office environments, router change often causes:
- Multiple computers showing printer offline
- Shared printers disappearing
- Network printer not detected
Best practice:
- Assign static IP immediately
- Use Standard TCP/IP port
- Avoid WSD
- Restart Print Spooler on affected PCs
This ensures stable long-term communication.
Why Reinstalling Sometimes Works Temporarily
Reinstalling works because:
- Windows re-detects new IP
- Port refreshes
- Driver resets
But if static IP isn’t assigned, IP may change again later.
Permanent fix requires network configuration stability.
Frequently Asked Questions
Why is my printer offline after new router?
Because the printer is either not connected to the new WiFi or Windows is still pointing to the old IP address.
Do I need to reinstall my printer after router change?
Not always. Often updating port settings is enough.
Why won’t my printer connect to my new WiFi?
It may not support 5GHz, WPA3 security, or may still be saved to old network.
Does changing router damage printer?
No. It only changes network communication settings.
Should I assign static IP after router change?
Yes. It prevents future offline problems.
