I AM UNABLE TO CONNECT THE SMART PHONE TO THE NIKON AW120. IT DOES NOT ALLOW ME TO GO THERE IN THE CAMERA

doing this might help:

1. Swipe down from the top of the screen with one finger.
2. Tap the Settings icon on the upper-right corner.
3. Tap the WiFi icon.
4. Tap the Menu icon on the upper-right corner of the screen.
5. Choose Advanced from the drop-down.
6. Uncheck the box next to "Smart network switch".

This is a computer issue, not a camera one

You need send your camera to service, your zoom lens stuck.

Did you try uninstalling the wifi and reinstalling it?

What smart device?
To connect it to a computer, you first have to install software and a driver, so the computer knows what camera you connect and what it should do.
When you have a camera connection kit for the iPad, you can connect the Nikon Coolpix S6800 direct to the iPad and it will ask you what to do with the pictures. You direct can access the pictures, download them on the iPad and deleted them in the camera, if you allow the iPad to do so.
I think other devices also should have connection tools and / or apps.
Next time, please also give us the device name and OS it is running.

It is in the manual page 92, but I print it here:
I don't like to type things what are already in black and white.
If you never have setup any wifi connection, this won't help, neither will a typed version I do. so if you don't understand ask someone close to you to help, with the description here.

The Smartphone connects to the camera NOT the camera connects to smartphone. You have to have the APP on the camera. You first have to turn on WIFI ON the camera. It is like a server. Then you turn on WIFI on the Phone and connect to the Camera WIFI.

Your TV must be a 'smart' TV i.e. it should have software enabling it to connect to the internet and access features such as Netflix. If you don't have a 'smart' TV then you can purchase a set top box which can be connected to your TV and will allow you to access on-line services such as Netflix. If you have a 'smart' TV then you still need to connect it to your internet router, either with an Ethernet cable or via WiFi if the TV has WiFi built in (or you can buy a WiFi adapter for the TV). If you connect with an Ethernet cable then the TV will connect to your router (and internet) with no further setup. If you use WiFi then you will need to access the WiFi settings menu on the TV and configure the settings for your router.

I have the same issue. I read and watched online tutorials about the compositors but after opening the set up I was unable to find any that had gone bad. I was able to upgrade the software by using a USB thumb drive but the issues are still there. I'm thinking of swapping out the motherboard and/or the power board next to see what the fix is.
