archive's connection fails

[Tom Coffin]

I have two kubuntu installs one on a dsl connection works fine. The other
is via wireless ISP.  On the wireless one when try to update the sources
list I get this error:
Err http:us.archive.ubuntu.com dapper Release.gpg
  Connection failed [IP: 146.137.96.7 80]
The error repeats for all the source sites.

My sources.list is correct apt-get,aptitude, and adept all give same
error.  I can surf the internet.

Need help with solution to connection problem. If more information is
needed will gladly supply it.
