So... My brothers laptop has been acting funny lately, and yesterday, for some reason, the internet stopped working. It tries to connect to my router wirelessly but it cannot connect at all, I tried to plug the cable in but it still wouldn't connect. Then I tried to log in to msn, that, of course, didn't work either. But in the dialogue box it says that there's something wrong with the DNS and the network... Something (Don't remember the name of it in english). Is there any way to repair this? I've got to get it fixed, I've scanned the computer using Avira and no result.
