What modem are you using? 

What signal light? The lan light? 

Go to netgear.com/support/   type in your actual model number. It'll take you to the support site with the manual that'll tell you what that light means

I posted picture for you bud can you help me I read the manual but it really doesn’t get into it much all I noticed is it said solid green it didn’t say anything about flashing and I was wondering if it is the problem I am having with my network being unstable it’s secure but not stable thank you

There's no picture showing. so not very helpful.

I added a picture to file the last light on right is not solid flashes constantly does that mean my network is unstable

When you add photos, click "choose file..." and add the file. Nothing is showing and if you add it using the photo option, a moderator has to approve it. 

Did you look in the manual what that specific light is and means?

I hit choose file and added a picture of a modem like mine it says in manual it’s the lan light has a symbol above it looks like a pc,phone and tablet mine flashing constantly it doesn’t say anything about that light in manual

instead of posting a picture. look at the label. probably under the battery cover.
