IP Fragmentation

I'm testing to understand fragmentation and not sure of the Wireshark interpretation. I hard coded the workstation to 1100 MTU and pinged 1100 to another host. The first captured packet is showing Fragmented IP protocol (Reassembled in #2), the second packet Ping Request (Reply in 3) and third packet Echo Ping Reply (Request in 2)e Ping echo request. With the IPv4 preferences Reassemble to fragmented IPv4 datagrams unchecked, the first packet is Ping request and the second packet is the IP fragmented. Can anyone explain? What is the correct setting and interpreting the fragmentation? Also, if this was UDP traffic such as audio/video, would it have an effect on the LAN versus the WAN with higher latency?
