HP Deskjet 2755 cannot rejoin network

[mikemarino1]

We have a HP Deskjet 2755. It worked fine for a week. Our toddler walked by and touched a button on the screen and it hasn't been able to rejoin our network since. We've tried every possible installation at this point that is available on the trouble shooting or other online guides. We've tried to re-connect it to our router via iphones, ipads, macs and pcs with no luck. We bought a USB cable to connect the printer to the PC and try to install that way, but also no luck. Holding down the WPS butotn when prompted on the router isn't working either. No matter what, once it gets to the join network step, it fails. I've checked our routers setting and we do not have mac filtering or any other setting active that would create an adverse condition. WIFI direct printing does work, but it's not ideal and also not what we paid for. 

This honestly doesn't make sense and it's making us so frustrated. It was working totally fine, and the original install caused no issues whatsoever, so it can't be an issue with the network, it has to be an issue with the printer and it's ability to connect, but I can't for the life of me understand how 1 accidental button press would make it impossible for the device to connect. There has to be something really simple we're missing here. Any advice would be extremely helpful.

Unfortunately those solutions did not work.

Could you please clarify your router brand and model?

By any chance, may you use a Verizon FIOS router?

You called it. It is Verizon FIOS. I think the router is a gateway but I can't tell what model. Thank you for your help so far, ShlomiL
