Airport express G not working with new linksys N router

Question

I just swapped a new linksys N router into my old G network and my old airport express is flashing amber and refusing to acknowledge the network. It does not seem to be picking up. What does this mean and how do i fix it? thank you in advance

someone posted this anyone , not sure i actually understand all of it
hours of digging through blogs and Apple help docs, with some luck and trial & error, have gotten it to work. This experience seals the deal...if a Mac can ever run Excel, I'm abandoning my PC.
For the benefit of anyone else in my situation, here's what I did:
You have to override Airport Express's default desire to make itself the hub of a new network, and force it to be added as a client to your own network.
First, plug the Airport Express into the wall, then reset it by holding down the reset button with a paper clip for about ten seconds. Plug in an ethernet cord that's attached to your wireless router.
Open the Airport utility which you should've installed from the cd in the package. It should now recognize your Airport Express and the light will turn green. Be patient...mine took awhile, and even started flashing amber before it worked.
You will need to manually configure the AE from the utility by typing in the name of your wireless network, setting AE to "join an existing network" instead of its default "create new network," and enable Airtunes.
You may need to add the "Airport ID" printed on the case of the unit to your router's MAC list. This allows the router to recognize the device. Type your router's IP address into the address bar of internet explorer to access the router settings.
If you don't see your speakers listed in a box at the bottom of iTunes, you will need to go to the settings window (in iTunes) and click "search for remote speakers connected to Airtunes."
gonna try it out, cause nothing else has worked
