When I powered up my router, printer, and computer Friday morning, I got a red globe and when I turned on the printer, the printer couldn't detect the signal. When I tried WPS on my G1100 router, the router found the printer MAC address but the printer still couldn't detect the WIFI signal. Same when I tried the Wireless Setup wizard. Is something in the router blocking it? Don't believe filtering was enabled in the router. Tried turning everything off and then restart but still same thing. No problems with the computer or iPhones attaching. MAC 10.15.7 just installed. HP Envy 4500 all-in-one-printer. Dom't know if it's something with the router blocking the printer or not.
