  • Try to ping from the PC's Windows command prompt to your router (e.g. ping
  • Check the settings of your router: Is DHCP enabled? Is the IP address available or already leased/used by another device?
  • Connect your programmed ENC28J60 module to the router.
  • Try to ping from the PC's Windows command prompt to the ENC28J60 module (e.g. ping
  • Is the green LED at the ENC28J60 Ethernet module's connector on?
  • Does the yellow LED at the ENC28J60 Ethernet module's connector blink when you try to ping?
  • If it doesn't work try to use an Ethernet crossover cable to connect the ENC28J60 Ethernet module to the router.
  • Sorry. The instruction printed to the serial terminal isn't correct. Please try to type into your browser and hit Enter (as indicated on the wiki page).

  • I'm referring to the two LEDs (green and yellow) built into the Ethernet connector of the ENC28J60 module.
  • Since ENC28J60 does not have Auto MDI-X capability, unless your router is equipped with such feature a crossover ethernet cable is needed.
  • Double check the wired connection between the NUCLEO board and the ENC28J60 module. Unfortunately I don't have access to a NUCLEO-L476RG board. However, I have sussefully tested the WebSwitch with a NUCLEO-F446RE board using the same pins as you tried for the NUCLEO-L476RG:

UIPEthernet  uIPEthernet(PC_3, PC_2, PB_10, PB_9); // mosi, miso, sck, cs
  • Even in case you do not power the ENC28J60 module from the NUCLEO board, make sure the GND pins are connect one to another!
