Decoding router lights can be tricky: for instance, a solid orange light might mean something completely different from a flashing one – whereas a router that resembles a 1970s dancefloor might actually be working perfectly. Luckily, The Big Tech Question is on hand with the ultimate guide to what the coloured lights on routers mean.
Note this is our summary to what each router light signifies. We include links to in-depth guides for more information, such as what flashing lights mean and how to troubleshoot problems, underneath the bullet points.
