Ken is on a limited budget and he installed a new OS on his old laptop, but he can't get online now. Leo says that it can be several things. It can be the ISP. It could be the wires coming into your home. It could be a configuration issue. One easy test is to see if your internet is working elsewhere. If your phone has WiFi, then you're in good shape. That would point to an issue with Ken's laptop. Try connecting the computer to your router with an ethernet cable. If that works, then the issue points to the WiFi radio itself.
