Before I make changes, I also want to mention that there are cameras connected to router as well. So is there some setting I want to keep so I don't mess up things. The Camera was setup by local engineer, I don't know how to do it myself, so I am little hesitant in resetting router.
I am uploading series of images of available settings in router.

Currently it's set to static
