HP Officejet Pro 8625 keeps losing WiFi credentials (Network name & password) & blue light blinking

[fallguytiger]

Hello, 

The HP Officejet Pro 8625 frequently loses its WiFi credentials (Network name & password) after a few days, and the blue light starts blinking, indicating a lost connection to the WiFi network. After re-setting up with WiFi credentials (Network name & password), the printer works perfectly fine with no issues for a few days, and the issue reoccurs with the blue light starting to blink again. I've rebooted the printer numerous times, the firmware is up to date, and I've performed a factory reset. It appears to be a firmware or software issue. Any help or guidance on this peculiar is appreciated

@fallguytiger, Hello and welcome to the HP Support Community!

Thanks for posting your question. I'm here to help you get things back on track.

I understand your HP Officejet Pro 8625 e-All-in-One Printer keeps losing Wi-Fi credentials, and the blue wireless light starts blinking after a few days. You've already tried rebooting, updating firmware, and even performing a factory reset—great troubleshooting so far!

This issue can be caused by several factors, including router settings, printer firmware behavior, or network environment. Here are some targeted steps to help resolve this:

Assign a Static IP Address

Dynamic IPs can change, causing the printer to lose connection. Assigning a static IP can help:

• On the printer control panel, go to Setup > Network Setup > Wireless Settings > Advanced Settings > IP Settings.
• Choose Manual and enter a static IP (e.g., 192.168.1.250), Subnet Mask (usually 255.255.255.0), and Default Gateway (your router’s IP, e.g., 192.168.1.1).
• Save and restart the printer.

Disable IPv6 on the Printer

IPv6 can sometimes interfere with Wi-Fi stability.

• Go to Setup > Network Setup > Advanced Settings > IPv6.
• Disable it and restart the printer.

Update Printer Firmware (Again)

Even if it’s up to date, reapplying the latest firmware can help.

• Download from the official HP site: Official HP® Support

Check Router Settings

• Disable Auto Channel Switching: Set your router to a fixed channel (preferably 1, 6, or 11 for 2.4GHz).
• Use WPA2-Personal Security (avoid WPA3 or mixed modes).
• Reserve the Printer’s IP in your router’s DHCP settings.

Restore Wi-Fi Setup Mode

If the printer keeps dropping off, re-enable Wi-Fi setup mode:

• On the printer, go to Wireless > Settings > Restore Wi-Fi Settings.
• Then reconnect using the HP Smart app or printer panel.

I hope the information shared has been useful and resolves your concern.

Wishing you a smooth and hassle-free experience ahead!

@Max3Aj, That was very helpful! I assigned the printer a static IP address last night, and so far, the printer has not lost its WiFi credentials (no blinking blue light). I will give it a week and report back. Thank you for being so helpful.

@Max3Aj, I will also try these solutions, in addition to the one listed above. Thank you again!

@fallguytiger, You're very welcome😊 I'm glad the static IP fix is working so far, and it's great that you're planning to try the other suggestions too. That proactive approach really helps narrow down the root cause.

Take care and have a great day.
