Thanks Ethel - you're so clever. I've printed this off to try when I get home. I had switched the computer off, but not the modem, which is downstairs and the computer is upstairs, which is why we bothered to go wireless. The internet light is on on the modem, but the light wasn't coming on on the router. When the message came up saying that we weren't connected to the internet, and we went through al lthe diagnostics, it came up with the problem with the router, and it was only then I realised the light wasn't on. I'll give that a go tonight as I say. While I think on, by "switch off the router" , is that "unplug it from the back of the computer"?
