Ethernet connected computer can’t find printer on the wireless network

  • My iMac is connected via an Ethernet cable. My printer is connected to the 2.4ghz wireless network. When I try to print the printer cannot be found. I have to turn on wifi on the computer in order to print. Why do I have to do that?

  • @rpalser I'm not sure if this is the issue, but some WiFi devices that only "speak" 2.4 GHz seem to demand their own network; i.e., they won't connect to an SSID that dispenses either 2.4 or 5 GHz connections. I just returned some LED dimmable and programmable light bulbs that would have required me to change my iPhone's SSID every time I wanted to turn one light bulb up or down (awful).

    Are you sure the 2.4 GHz network being dispensed by your router is on the same subnet as your computer?
