red ethernet light f3

[utdsudzy13]

hi does anyone know why my eithernet light on router lights red wen plugged to f3 but its green wen connected to any other device with same cable.

It may be because the F3 uses 10Mb Ethernet, and your other devices use 100Mb Ethernet. Check your router manual.

Is it a sky router? Mine does the same. It's still online though
