Rpmfusion problems

[james tate]

Fedora 15  i686

With rpmfusion in the /etc/yum.repos.d .

when running Yumex I get error ;

Cannot retrieve repository Metadata (repomd.xml) for repository: 
rpmfusion-free , Please verify it's path and try again.

I can't even do the following command and get the two rpmfusion.rpm to install, like it can't find rpmfusion.org, I have  to download the two rpm's and use yum localinstall --nogpgcheck to install the rpm's.

su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-
nonfree-release-stable.noarch.rpm'

This is a New Fedora 15 install could there be a problem with my Network 
Setup,  I can't even get PlayOnLinux to see the network connection, but 
everything else can connect to Internet, Yum, Firefox, etc.
