# W6100 Issues

## Question

Asked by NUK on 2024-04-29 in Ethernet Chips.

Hi everyone,
I am trying to interface Wiznet W6100 (MKR) Eth Shield with Arduino MKR Zero. I am using SPI connection along with Wiznet Ethernet-IPv6 Library. I am trying to ping Eth Shield using IPv4 but I am unable to ping. Although, when I use IPv6 ChatServer Example, Eth Shield works fine and I can ping successfully. But when try to use IPv4 functionality to ping, it gets failed to ping.
Please guide on how to ping ETH Shield using IPv4? Do I have to switch to any other Ethernet Library?
