well....
DHCP, i wouldn't worry about. just pick an IP address that is high in the DHCP range that is fairly unlikely to be assigned by the DHCP server to anything else and use that.
i use easynet from amigakit with one of my A1200's and a wifi card.
and the genesis TCP/IP pack on the 3.9 CD for another machine.
to be honest, an 030 is fine for skurfing the web on nice easy sites like amiga.org or aminet.net. things like fblit help the images too....
