Problem is now solved - all connections are now working perfectly !!!
I fixed the problem by identifying my IP address & proxy server type information at http://www.ip-adress.com/whatismyip/ - I also needed to enter the proxy address number rather than it's name.
I found "Internet then Network" connection with HTTP proxy(connect alive) to work best for me.
Thanks again, Elecont weather just keeps on getting better
