Debian install Question

[M.R.P. zensky]

Hello I am installing Debian on a amd processor computer. I connect to the net 
with wifi. I have tried the net install iso and it did not work. I think I need 
the unoficial stable non free firmware included. I select a mirror site but 
Here I am confused about what iso file I want. I am also assuming that I need 
an image for cd-rom. Any help would be apreciated.

Problems installing Debian

[M.R.P. zensky]

 Hello I have successfully installed ubuntu linux on my system but I want to 
use Debian. I download the iso file from their home page. One problem that I am 
having is the Debian install menu asks for if I use a network card. I don’t I 
use home based wifi which I don’t see an option for this. The other problem is 
that it asks for a proxy for adding a repository.  I don’t know what to do with 
this either. How do you connect Debian to my home wifi?
