Why does my Color LaserJet Pro MFP 3301 keep going offline?

[Spencer02138]

I have called support four times for this issue in the past six months. The representatives suggest that the printer has to be within eight feet of the router. I have an extender less than eight feet from the printer, but that, it seems, is not good enough. Also, the printer shows that the signal strength is excellent.

@Spencer02138, Welcome to the HP Support Community – it’s great to have you here!

I appreciate you taking the time to share your question. I'm more than happy to assist with this and provide a solution that works for you.

I understand how frustrating it can be when your Color LaserJet Pro MFP 3301sdw keeps going offline, especially after multiple support calls. Let’s walk through a few steps to help stabilize the connection and ensure reliable printing.

Avoid Using Wi-Fi Extenders

Even if the extender is close and signal strength appears excellent, HP printers often struggle with extenders due to:

• IP address conflicts
• Network isolation
• Delayed response times

Recommendation: Connect the printer directly to your main router’s Wi-Fi network (2.4 GHz band preferred). If the router is far, consider relocating the printer or using a wired Ethernet connection if available.

Assign a Static IP Address

This prevents the printer from changing IP addresses, which can cause it to appear offline.

Steps:

• Print a Network Configuration Page from the printer.
• Note the current IP address.
• Access your router’s admin page and assign that IP as static for the printer’s MAC address.
• Alternatively, set a manual IP via the printer’s Embedded Web Server (EWS):
  • Open a browser and enter the printer’s IP.
  • Go to Network > IPv4 Configuration.
  • Set to Manual IP and enter the current IP, subnet mask, and gateway.

Disable IPv6

Some routers and printers have compatibility issues with IPv6.

• On the printer’s control panel or EWS:
  • Navigate to Network Settings > Advanced Settings > IPv6.
  • Disable it.

Update Printer Firmware

Outdated firmware can cause connectivity issues.

• Visit: Official HP® Support
• Enter your printer model: Color LaserJet Pro MFP 3301sdw
• Download and install the latest firmware.

Use HP Smart App/HP App

These tools can diagnose and fix offline issues automatically.

• HP Smart

Power Cycle and Reconnect

• Turn off the printer, router, and PC.
• Wait 30 seconds.
• Power on router → printer → PC (in that order).
• Reconnect the printer to Wi-Fi manually via the control panel.
