Today the hard disk on my old computer decided to fail on me so I purchased a new PC. However I tried to hook my router up to this new computer and I can't connect to the internet through it. I don't know much about computers when it comes to troubleshooting the technical stuff. Although it's telling me my Local Area Connection doesn't have a valid IP address and it's not even detecting my router. Is there something specific I have to do in order to get my old router to work with this new computer? Any help would be greatly appreciated. Thanks.
