Hello, my name is Rusty. Unplug your printer, and set up the wireless again. Sometimes they can lose their connection.
Also, press the reset button on your access point briefly, just to soft-reset it. This usually restores communication. You may need to go through the wireless setup on your printer again. Tell me the results.
Keep me posted Maurice, the reset button should fix the problem if it's the router. Definitely change out the ethernet cable, and let me know how it turns out.
