Next up, power cycle your router and modem. This involves unplugging both devices from the power outlet, waiting about 30 seconds, and then plugging them back in. This process allows your router and modem to reset their connections and can resolve many network-related problems. Make sure you plug them back in the correct order too – modem first, then router. Another crucial check is to ensure that your Wi-Fi is turned on. This may seem obvious, but it's easily overlooked. Check the Wi-Fi icon in your system tray (usually located in the bottom-right corner of your screen) and make sure it's enabled. You can also check your laptop's physical Wi-Fi switch, as some laptops have a physical switch that can turn the Wi-Fi on and off. If that switch is off, you won’t be able to connect, no matter what! Another quick check is to verify that you're connected to the correct Wi-Fi network. Sometimes, you might accidentally connect to a neighbor's network or a public Wi-Fi hotspot. Make sure you're selecting your home or office network from the list of available networks. These simple steps can resolve a surprising number of wireless connectivity issues, saving you time and frustration. If these preliminary checks don't fix the problem, don't worry; we'll move on to more advanced troubleshooting steps in the following sections.
