I think it is something else, something in the browser or OS. I think the modem
is talking but the software is not working with it. Because it says 57-75% and
blinks without the Red ! in the icon. It just wont talk from the browser. Any
ideas about that?

It could have something to do with my set up as well. I don't know much about
the connection with the router in the hall. I did manage to get a list of the
IPs in it. But parts of the Ubuntu software only allow me to enter the data but
the buttons to click to finish are not active then.
