Service Error 79 stuck in a loop & turning off the network hasn't worked

HP Color LaserJet Pro MFP M281fdw

I moved and now my printer is stuck in a Service 79 error loop where it keeps restarting.  

I put the printer in my car, so it isn't damaged.

There was a paper jam that I cleared, but the Service 79 error and restart didn't go away.

I read another thread to turn off my router, but as soon as I reconnected the service error loop has continued.

I turned off my wifi, downloaded the firmware, plugged in via USB, but as soon as I turn on my wifi I have this issue.

I only use my printer via wifi.  I never used support, now my printer is out of warranty by 1 year, and now have no way to get help.

Thoughts on how you would solve this pain?

Additionally, I plugged in directly to the computer via USB and it prints, it just doesn't work with the wi-fi.

I did a factory reset, deleted the printer from my computer. 
Upon connecting the wifi, it immediately does the Service 79 error.

I saw another google answer that says to change out the DIMM, but I have no idea how to do that on this model, and it seems the issues is only with the wifi.
