Off Topic: Your AirPort Router blinking amber with connection ok
The blinking amber light (instead of the usual green) while the connection is working well is a signal that a new update to the AirPort Router is available.
To download and install the update:
Choose the Finder and in the very top Menu Bar choose Go.
From the list choose Utilities and then AirPort Utilities
Click on the picture of the Router to open its information screen
Alongside version will be the option to Update.
Download time is not long but the short term disconnect for installation and return of the green light ons the Router feels like forever. It is actually a minute or two.
And you're good to go.
Good luck.
