you will always get this error message, when your router is not able to identify the internet connection from your modem.
so let’s try to reboot your modem once, and wait for one minute.
now check what colour of light can you see on the linksys router? if you can see the solid blue or green light. it means, you are getting the internet on your router.
all you need to do, just run the linksys connect setup again and it will give you the congrats message on your pc.
But after rebooting the modem, if you still get blinking orange light on your router. then you need to call your isp, and ask to them about your isp configuration.
once you will get the configuration, you need to go ahead and setup your linksys wireless router manually.
