As long as easynet wired card works the same as netgear without problems I am with you there!!
Yeah...it may have being stated there when I thought a USB version was available since it all went back to PCMCIA again...I decided to change my mind. From vast experience, frustration, upgrades and hassle I got nothing more than trouble with WiFi and no success. Maybe where I live WiFi is not an option for Amiga...but again, Amiga's lacking of latest hardware, software and driver renders the concept of having a WiFi almost impossible. And already it is impossible to have it through USB.
OK, from my memory you need to buy a Netgear MA-401, install Prism2 device driver from aminet, them install Card Patch and Card Reset also from Aminet.
Then install (Roadshow/Genesis/Miami/AmiTCP)TCP/IP stack and you are good to go.
It's been many years since I had this set up on my old A1200 tower though.
