I use a Linksys BESFR41 (
http://www.linksys.com/Products/product.asp?grid=34&scid=29&prid=20 ).
Works fairly well, and all of the configuration is done via a web interface. Has great features too. Umm... I think I managed to get to the configuration page with my Amiga too. (I'll have to double check.)
I use an XSurf, Miami 3.2b and an A4000D. It was strange, at first it didn't want to work, and then suddenly *poof* it worked. I'll forward you my Miami configuration if interested (I'm at work.)
