Hi!
Could somebody please, please, pretty please with lots of sugar on top
help me with this? Especially after my Fedora Installation failed last
night, I'm still convinced that I want to stick to Ubuntu. And I don't
have access to a wired LAN at home without switching off the WiFi net
for the family.

Thanks a bunch!


Cherrioh!
