If you're seeing a blue light on Netgear router (https://routerlogln.com/blue-light-on-netgear-router/) and experiencing connection issues, start by checking whether the router is properly connected to the modem and receiving a stable internet signal. A solid blue light usually indicates a good Wi-Fi connection, while a blinking blue light means the router is trying to establish a link. If the blue light on Netgear router keeps blinking or doesn't turn solid, restart both your modem and router, verify cables, and ensure your ISP is not facing outages. Updating firmware or performing a quick reset can also resolve persistent LED issues.
