Not a firefox issue.

The fact that it works from the windows box shows that the address is
visible from your location.  That wget got a 404 says that the request
the server received was not for the same file that the windows box
sent.  It implies that the linux boxes are mangling the address somehow.

I would guess at the CentOS server.  You could take the fedora laptop
to a local access point and try to get the file from there.  If it
succeeds, that says it is the CentOS server.  If not, there is
something wrong in the protocol on all the linux boxes you're sending.

I've given pretty much all the help I can.  At this point you need
to set up some packet monitoring on the CentOS server and try both the
wget from fedora and the browser request from windows.  Compare the
packets.  There must be a difference.  I don't know the details of how
to do that, though I'm pretty sure it isn't that difficult and is
available in linux.
