And you can take a screenshot of it, like you did before with the ping utility... Simply pressing the "printscreen" button should open up the screenshot program.
Just in case:
Otherwise, yes a photograph would also work, especially if you want to post pictures of the router, so we can determine the model. But then it's easier if you figure out the model yourself an tell us.
This will be useful to give instructions for the router configuration.
It would be really interesting to know if the websites work after a clean install of Windows (i.e. without installing any additional software from your ISP!).
So yes, please do try it with Windows again and let us know.
But don't forget that you can dual-boot! (Install GNU/Linux after Windows for that)
I'm still dual-booting after 5 years of GNU/Linux (even though I barely use the Windows entry at all these days, not even for games, which is the main reason for still dual-booting ^^).
P.S.: I still don't know if you connect by wire or wireless, which router you use, etc. And you never posted all the files I asked for...
