Nighthawk AC1900 Model EX7000 SN 46D57C7FA2717

thanks.  there no lights on.  i powered it off and then on.  there are now green lightes.  I recall, when I initially set it up, there were green lites.  However, they had since gone off and I didn't realize that until your response.  Why would they have gone out?  I did move it and so pulled the plug out.  Could that have done it?  So green lites and it's working.  But how do I find out if it's really helping here in the house and actually extending the signal for me?

I'm really getting sick and tired of these antennae falling down.  I wrote to Netgear support about it the same day I originally started this thread. But haven't heard a word back.  do you think I should get a replacement?
