Extraordinary delay in accessing web-site

[Timothy Murphy]

I have a Linksys WVC54GCA camera in a remote site,
which I access at http://xyz.com:8080 on one of my Fedora-18 laptops.

For some reason there is now a delay of an hour or so
in getting the image on my laptop.
This occurs on both my Fedora-18/KDE laptops,
whether connected by WiFi or ethernet,
and whether using Firefox, Chrome or Konqueror.
But it does not occur - I get an immediate view -
running Windows XP on the same laptops,
or on my server running CentOS-6.4.

With Firefox I get the message "Connecting to ..."
and then (endlessly) "Transferring data from ...".

Any enlightenment gratefully received.
