Not too sure what's gone wrong but my daughter has disabled her wifi connection of her computer and can't nwo get connected. What can she do. The light comes on but there's no connection? Sorry it's so vague. Any ideas.
Have a look in the 'tools' tab, work offline may be checked, if so uncheck the box and all should be fine. This happened to my laptop a while ago, it took me a while to find the problem! hope this helps.....................welsh
