Hi. I have a network at home consisting of a main PC, with a Linskys router attached to my cable modem, which then serves two laptops which all works well and has done for some years. That's the good news! A few years ago we planned to go on holiday with some friends, so they came to us with their laptops, I gave them the security code to my network (WEP enabled) they logged in and we all merrily searched away to find our perfect holiday. When we recently tried to do the same again to book another holiday, none of them could log into my network. I do have vague memories of within the last couple of years, of reading in Webuser, a way of making a wireless network more secure and stopping other poeple logging onto it, thinking what a good idea that was and adjusting my settings accordingly. Unfortunately I can't remember what I did or how to undo it! Any suggestions gratefully received.
