I put my Nissen ITTL flash on my 7100 for the first time and could not get a satisfactory shutter fire or exposure until I put it on Auto which I had never used up to this point. Pop up flash was the same. I did not have this issue with my D90... I think. I need to read the manual some more and see if I have an issue with the auto focus. The modeling light was on. New Gear is always a challenge or so it seams. Am I missing something or do I need to go back to flash 101 in the manual. I have not order the Nikonian 7100 book yet. I will do it as I close this post. JBD90 (now D7100)
You probably need to go into a lot more detail about what you mean by "could not get a satisfactory shutter fire or exposure". What was your subject? What were the ambient lighting conditions? What were the flash and camera settings? What were the results?

If I recall the room light was low, the shutter speed was set to 60 and Shutter priority. Moving Child... what else. Focus was set on single spot. Shutter fire should have been stated as shutter lag. Push nothing .... focus hunt.... nothing ..... kid gone.... no shot. When I tried the pop up flash the same situation. When I test fired on a far wall ornament the exposure was dark. I kept trying to increase the exposure compensation with no effect. I kept cranking it up and when I reviewed four shots in a row they were identical. the comp had no effect.
When I set it to Auto, it was instant shutter and flash and the TTL worked fine, exposed for subject.
I should have taken notes for further research but I am not that patient. JB
Long shutter lag: you probably have red eye reduction set.
Poor exposure: ltd of things to go wrong, but the first thing I'd guess is having the flash exposure mode set to TTL-BL rather than TTL. BL means balanced, as in fill flash. Regular TTL means that the flash is the primary illumination.

You need to go to the Nissan website and update the flash so it recognises the D7100, your Nissan flash is unaware of the new camera or its firmware, updating the flashes firmware will resolve the issue.
Having the same problem with the built-in flash indicates a problem with settings. If the AF is hunting and you have the camera on Focus priority, the shutter might not release due to not having enough light to focus. As a test, put the camera in Release Priority and seen if it fires as excepted, but likely missing focus. If the light is low, the AF Assist Light function will greatly aid focusing. Nikon flash models from the SB-600 and up have an infrared patterned light for focus aid that is not noticed by the subject that way white light assist light does. This missing focus is more common with slow lenses because metering and focusing both occur with the aperture wide open. So even if you are stopped down on the aperture, a faster (smaller maximum aperture) will focus better in dim light. In really dim light my 24-70 2.8 is better than a 3.5 maximum kit lens in getting focus but my 24 1.4 can focus almost in the dark. I am assuming you mean "modeling light" when you wrote modeling light, instead of Assist light. Stan St Petersburg Russia
