So... I have installed the drivers for my Amigakit PCMCIA Wireless networking card and installed Easynet.!
I have the same card. It works just fine on my A1200 030 but on A600 3.1 ACA020 doesn't even flash LEDs. I copied A1200's OS just if I forgot something on settings but no luck. I think it's a PCMCIA prob for me and I have nothing else hardware to test the socket :-(
