ppp0 refers to dial-up or telephone modem based connection. eth0 is 
generally your ethernet connection, although depending on your wireless 
card it could also show up as an eth(0-9) entry. It could also show up 
as wlan(0-9).

Just a guess, but I would say ubuntu found your modem and your ethernet 
interface but was unable to configure your wireless interface. Give us 
some more details, what type of wireless card is it (pci, pcmcia, built 
in to a laptop, etc), who makes it, what model number, what chipset, etc?
