I have had malware and other issues that I think I have cleaned off. In the process, somehow I screwed up something and now I can't connect to the internet. It is an HP win.7 laptop. I know it's not a router issue because nook, kindle, phone...all connect just fine. My laptop shows it is connected to our wireless but when you open the browser, nothing. When I troubleshoot, it finds nothing. Connection Status-IPv4 shows internet...but IPv6 says "No internet access". Realtek wiFi adapter is "working properly". I am at a loss as to what else to do. Please help, I'm a teacher who can't afford to take it in! Thanks
