LaserJet MFP 100NW display Error 79 Turn off and on again

[sk58]

I switched my internet modem and lost connectivity to printer (LaserJet MFP 100NW). I wired the modem with printer, got the IP address and setup the new SSID and password in Printer Webpage. It all seemed to work well. However, when printer restarted, it started displaying "79 Error Turn Off and Again" and then turned and turned on itself, and went into a cycle of turning off and on. I tried turning the printer off, removing  power cable, and started but same error happened again. 

While trying different things, I turned the modem off and then started the printer, and it started normally. When I turned the modem back on, the error appeared again on the printer. It is apparent that when modem is on, printer can not communicate  with modem and generates the error.

How to fix this issue?

Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).
