In the end it was the router. As soon as I plugged one of mine in, it saw the DSL and reported.
Then the Sky admins told me they could not divulge the DSL username and password as they don't have it..... Ria decided to sign for another year and get the free router and didn't want me to go and get my mobile so I could get onto Google and hack the router to get the login details.
She'll be online again early next week at home.
Ria, you're welcome. I have little to do in the evenings and am local. So why not, it's not difficult for me and we all try to help. Plus I was fed a lovely meal and watered.
