Perform a speedtest or download from FTP server. Would like to figure out from wireshark, how to identify the packet loss rate? Does Wireshark has this capability?

You could filter for TCP expert messages about "previous segment not captured", by filtering for

tcp.analysis.lost_segment

and check the status bar for the number of occurrences. It's not 100% exact under all circumstances but it can give you an idea. With UDP it depends on the application protocol if you can check for packet loss, but it's more complicated because UDP doesn't guarantee packet delivery - which means that there are no checks for lost packets on UDP protocol level like TCP has.
