|Depends entirely on the manufacturer. I have a router that shows a nice shade of pink during its boot process. This is brought about by a combination of blue and orange. |
The orange light flashes during the synchronisation phase. Once the Modem has synchronised with the equipment at the telephone exchange the orange light goes steady and the blue light comes on while the log-on to the ISP is accomplished. Hence the pink.
Once the log-procedure is completed the orange light goes out and you are left with just a steady blue light.
So unless you have a BT Home Hub version 3, I doubt if your Router has a pink light.
