Thanks for your help, though I'm not techy enough to understand it. Should have said that when it comes to computers I need someone to tell me where the boxes are and what to put in them - anything like "address range segment" goes so far over my head you would barely believe it!

I've downloaded and installed the Jetadmin from the web and have no idea what to do in it - doesn't seem to want to save anything I try to change like the subnet mask (not even sure if I should be trying to put that in Configuration but its there and I can copy the number from the Router settings screen!)

The Router shows it as occupying 192.168.2.3 but if I type that into the browser I get "page can't be displayed" or similar, and when I'm in Jetadmin it will print the test page OK but asking it to upload and print gave me garbage.

It doesn't appear anywhere else as an available printer and my head hurts so I'm going to forget it for tonight!
