-If the link LED is off, check the connection of the cable first, and if the cable is fine,
check the condition of the link LED after putting the ezTCP/Ethernet product to the ISP mode.
-If the link LED is only turned on while the ezTCP/Ethernet product is in the ISP mode, the firmware has chance to be wrong so we recommend that you upload it again.
-If the link LED is not turned on even in the ISP mode and the cable is fine, the product needs repair.
