Thanks for the ideas! It says WPS for security, with WPA2-PSK enabled. I have to use 2.4 Ghz unfortunately as this printer that I only bought a year ago doesn't work with 5Ghz. The channel doesn't appear to be congested (it says interference level "acceptable") but I can't keep changing it every time I want to print something. Re: 3. for static ip, is there any other devices configured? one way is to connect to your network, either by wired or wireless, execute ipconfig in command prompt (windows) or ifconfig in terminal for mac. e.g I'm not positive I'm understanding your question. If you're asking if I have other devices connected to the wireless network, yes. I have two Rokus, my laptop, my iPhone and my Alexa.
