- Port Unreachable

Just purchased BSD3.

Installed the licenses , authorized, began download.

Stalled close to the end. Eating all day to finish.

Checked with ping
result Destination Port Unreachable.

Called the ISP provider (COX), they can ping it, I cannot. Reset the WiFi - downloaded for 1 min, stopped.

What is the solution? Are there alternative way to download it?
