I'm not sure if this is a printer or network connection. I have a HP Officejet 6800 on a Wi-Fi connection. Periodically, when we go to print, we find that the printer is disconnected. I use the WPS connection method, which works find, but I have no idea why this is happening. Any thoughts:? The router is part of a Comcast Gatewway modem/router device within 8 feet of the printer. We are on Windows 10.
