HP Envy Pro 6400 keeps going offline

[sare46]

My printer is connected to our home router, and keeps going offline. I can't seem to rectify the problem so it just have to pull the power adapter out and back in again.

Can anybody tell me why this keeps doing it and if there is an easier way to get the printer back online again?

Many thanks

@sare46, Welcome to the HP Support Community!

I understand the printer goes offline. Let us try these steps:

Assign a static IP address to the printer

• Obtain the IP address of the printer – You can touch the “wireless” icon on the printer control panel to obtain the IP address.
• Type the IP address at the top of your web browser to obtain the printer EWS page on your computer.
• If you get any security notification, click on show details/advanced and 'proceed to this website'.
• Go to "Network" tab - General - Select "Network protocols" - Select "Enable IPv4 only" (or similar) - Apply the settings.
• Go to the “Network” tab – Click on “Wireless (802.11) – Then click on “Network address (IPv4)
• Click on the radio button which says “Manual IP” and then click “Suggest a manual IP address” to give a manual IP address to your printer.
• Click on the radio button which says “Manual DNS Server” and under manual preferred type 8.8.8.8 and under manual alternate type 8.8.4.4 (This is Google DNS server address)
