Staring at a red light on Linksys router can definitely be frustrating, but typically it is quite easy to resolve. This light usually signals some sort of trouble, loss of internet connection, a firmware pane, or power problems. This is why you must remember to unplug the router for 30 seconds and then plug it back in. Check all the cables, and verify if your modem is working well. https://linksyswifiextender.net/red-light-on-linksys-router-cause-and-solutions/
