Solid Red Power light, 2 yellow light. Constantly on

[Zad23]

I wasn't getting internet access, so I unplugged it, waited at least a minute, and plugged it back in. It usually runs through its process. This time it goes immediately to solid red power light and the two lights just below are solid yellow. Anyone know what's up with that? Thanks!

Which router model?

Which firmware? (not "the latest")

Have you done a factory reset?
