When you already have a Wi-Fi router and mobile devices with 5G or LTE, there’s almost no reason to even think about the hotspot feature on any of your devices unless your ISP is down. But recently, I faced a completely different issue. My Wi-Fi router stopped working altogether, but my internet connection itself was perfectly fine. I got my PC back online by plugging the Ethernet cable from the fiber ONT directly into my motherboard’s Ethernet port, but that still left my MacBook and iPad without Wi-Fi.
