Neptune only began including WiFi capability with the newer 2016 Apex and the Apex-EL. The only wireless option for a Classic is to use a 3rd-part wired-to-wireless adapter, frequently used for gaming systems. Most people have had success using the Netgear WNCE2001, but I believe it has been discontinued. Search Amazon or other sellers for "wired to wireless adapter" and you'll find something.
