kppp is for dialing with a modem typically.
Did it give you an ip address similar to this:
[email protected]:~$ /sbin/ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:76:B7:FD:CB

eth0 is your network device, while lo is your loopback device. Can you use a physical LAN to connect instead of wireless? Might also try giving the command iwconfig a try as well.
I found this doing a quick google, not sure if it'll help you out though.
