Last October for his birthday, I purchased an HP laptop for my son from Best Buy for approximately $430. It was a new laptop with Windows 10 preinstalled. It wasn't long before he had to return it to Best Buy's Geek Squad for a problem unrelated to Internet access. In the last month, he lost access to the Internet. I tried to connect his laptop to my wireless system, which works well for my laptop and other devices. Couldn't do it. So I connected it to my router with a cat 5 line. It displayed on his computer that it was connected on a cat 5 line but still no Internet access. Without Internet access I can't run a scan to check for malware or a virus. As a last resort, I thought of uninstalling and reinstalling Windows 10, but I wanted to check here first to see if that would even work.
