Each light on a router’s control panel indicates a particular action or status of the router. Generally, the flashing green light indicates that your router is online or active. The flashing lights does not necessarily mean there is a problem with your router.

In some router models, if the LAN light flashes in green, then it indicates traffic/usage on the local network. But in most routers, the flashing green light indicates that the router is starting up. When it comes to the Power light, a solid green light indicates the router is connected to the power properly. Carry out the below-mentioned steps on router green light flashing.
