This is in a sense a continuation of another post (https://www.bleepingcomputer.com/forums/u/805118/saluqi/) but since the original issue there (router configuration) was resolved I thought it better to start a fresh topic and spare people reading through a huge mass of mostly irrelevant stuff. If I am mistaken, perhaps someone will correct me.
I have a home WiFi setup with a LinkSys router, 2 computers and a printer. The printer is HP Photosmart 6525 printer/scanner. The computers are a desktop Dell XPS 8700 and a laptop Dell Inspiron 15R. The problem is, in a nutshell, network access to the printer. The printer is connected to the desktop by a USB line, but to the laptop only via WiFi. As a result the printer appears under "Devices" twice on the desktop - once as itself ("HP Photosmart 6520 Series", the hardwire connection) and once as "HP1C6A1F (Photosmart 6520 series)" (the WiFi connection). On the laptop it appears only as the WiFi version. On both it is grayed out and "not connected". If I keep the computer awake long enough (more than 24 hours) the network (WiFi) printer may become connected, or it may not. The desktop is set to go to sleep after a relatively short (30 minutes) period of inactivity. The laptop goes to sleep only if the lid is closed.
Both computers are acting most of the time as if the printer were not on the WiFi network. If I renew the printer login to the network, it may come to life on the computers for a while, but after a couple of days it drops out again.
Of course that does not matter for the desktop, because it has the hardwired connection set as default. For the laptop it means I can't print from the laptop without complicated time-consuming contortions, if at all. The laptop spends most of its time here in my home office, but it travels with me to other offices (I am a peripatetic water-system operator and consultant) where I may wish to upload documents or drawings for further study at home. Not being able to print is thus a major nuisance.
When I look at the printer itself it says "Connected" but "Wireless Direct Off" (whatever that means). I can re-connect the printer to the network by re'running the "wireless setup" on the printer, but it still appears as grayed-out and "not connected" on both computers.
So the critical question is, what do I have to do so that the printer comes up as "connected" when I bring the laptop home and it reconnects (automatically) to my WiFi network. The laptop IS connected, it says so and I can go on the Internet, etc., without difficulty. But the network printer remains obdurately "not connected".
Today I did use the laptop in the office of a water agency for which I am Operator. I was online there for a couple of hours, doing very prosaic stuff like sourcing bits of laboratory equipment. Now that I have it on my network at home, it is displaying a new "device" called SSID_MediaMover. I gather that is a driver associated with the Belkin router to which I was connected by WiFi in that office. Something to worry about? Should I remove that "device"?
Thanks for any words of wisdom here!
