Roadshow is the best TCP/IP stack for the Amiga, it just works and its fast. Just recently I tried to download it again but my link had expired.I had purchased it back in 2013!
So I got in touch with Amigashop.org and very quickly I got an email from Andreas Magerl who resolved it for me. Amazing guy and an amazing service. I really love being a part of the Amiga community.
