Epson WF-C579R (No Lan) after code activation

[edx 0]

I am writing to inform you about an issue I encountered following the purchase of a chipless activation code for my Epson C579R printer. 

After successfully updating the firmware and activating the code, I noticed that the LAN network connection is not functioning. Despite my attempts to troubleshoot the problem, I have been unable to resolve the issue.

I would greatly appreciate it if you could provide guidance or assistance in rectifying this matter at your earliest convenience. 

Thank you for your attention to this concern. I look forward to your prompt response.
