How long did you hold the reset button in? needs 15 seconds before the top LED blinks yellow/orange Then after it start slowly blinking white, hit the sync button on the satellite then select sync on the routers web page under the Add Satellite section.
What version of FW are you using on the router and satellite?
If the above process doesn't work, then contact NG support and ask about an RMA.
