Okay,
I am making an assumption that your phone is a Samsung and not a ios device.
On the watch ⌚ set WiFi to Auto (on the watch slide a finger from the 12 o'clock position down to enter quick settings, look for the cog (a star with a hole in the center), swipe from right to left if it us not immediately visible.
Slide your finger down the Settings menu (or rotate the bezel) until you get to Connections, then Wi-Fi, now Auto, select it. Press the bottom button (Home) on the right, to take you back to the watch face.
Slide your finger once again down the screen to check the watch status; you should see the battery and the Bluetooth symbols at the very top and the bottom should say 'Connected using Bluetooth'
Now on your phone 📱 slide down the notification shade and unselected Bluetooth (Turn off Bluetooth).
You watch will vibrate and a picture (symbol) of the watch will appear at the 12 o'clock position.
Slide a finger down the watch screen, you will see the words 'Stand alone' at the bottom of the screen.
Now wait about 15 seconds, and your watch will vibrate again, it will then flash the name of the WiFi network. Now when you slide your finger down the watch screen again, it will say at the bottom 'Connected remotely' and at the top left you will see the WiFi symbol.
Hope this helps
