Apple Airport router
What does a blinking amber light on my Airport router mean?
Something is wrong.. or something needs attention.
You need to open the airport utility and click on the airport that has amber .. the summary page will list the problem/s.. post that screenshot and we can possibly help you.. but the method is to just click on it and see what wizard suggests.
eg here is my most severe listing yet.
Select each one and pick ignore.. ie stick your head in the sand and pretend there is no problem.. some of the issues cannot be "fixed" that easily.
