HP Envy 7640 keeps going offline daily

[SharonG711]

I have been having the issue of my computer going offline almost daily for probably close to a year. I keep unplugging and reinserting the power cord to get the printer to work. I have tried using the HP Print and Scan Doctor, manually setting the default printer (which always is set but printer states offline), checking the printer port and Windows services status, creating a manual IP connection and connecting the PC to a TCP/IP Port. The only thing I can think of is we are now using an all-in-one modem and router from Comcast. My husband has his own printer and he does not have the same issue as I do, All the setting seem to be the same. Thank you.

@SharonG711, Welcome to HP Support Community!

I see that you're experiencing printer offline issues and I appreciate your efforts in trying to resolve the issue. Follow some additional steps below and see if that helps-

Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

You may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best. You can contact your ISP for help.

Keep me posted for further assistance.
