gidday Keef,
I connected the netgear router via ethernet to the netcomm modem/router, then the desktop via ethernet to one of the 4 ports on the router, and left the ADSL line intact (in the modem/router).
Looked gorgeous, all those flashing lights where they should be, but I then couldn't access the internet on the desktop.

Needless to say I didn't try with the lappy - I figured that wouldn't go there if the desktop wouldn't.
Tweaking isn't my strong point ...
