Hi @navyveteran ,
WiFi connection errors are unrelated to Klipper. Also, the Neptune 4 series uses a modified Klipper and Linux system.
3D Printers with Preinstalled and Modified Klipper Versions
With that said, I would first isolate the issue. Can another device connect to the extender? If so, it’s likely a problem with the printer and you should reach out to Elegoo support. If not, reach out to Vonets.
