Hehe....really simple answer in the end..
A few weeks ago I added a Proxy server address as I was unable to access Yahoo mail without it. Initially I did not have bypass proxy for local addresses... so I ticked this on and tried to connect to the Netgear page... but nothing.
So I just removed the proxy address and hey presto, it works...and in fact so does Yahoo mail now...
Thanks for all your suggestions!
