I have done that. I've tried entering in my own IP address and also tried creating a new one by changing the last digit.
Problem when I am setting it up is on my computer, it just stops at "restarting printer" even after my printer resets and runs all the "diagnostic" stuff.
Update: Found issue. I created a new port in my printer properties. Finally works wireless now!
Good legitimate waste of 4 hours+. Nonetheless, thank you for your help!
If you could share how you set up the new port in printer properties that would be great. I have same printer. I have it detecting and connecting to my router, the problem seems to be that the printer is set to COM3USB port, not a wireless port.
