Please visit Bolt Setup Debugging WiFi Connection and perform the steps as given. You will also find a lot of debugging steps on this link.
The steps to proceed from this link will depend upon the status of the Blue LED of Bolt (Blinking or Not Blinking). Please choose the correct link as you proceed in the debugging.
Do read each step carefully and perform. Please note that Bolt might be little slower in the Access Point (Hotspot) Mode so WiFi connection might take as much as 2-3 minuets to connect.
Note: AP (Hotspot) Mode is when Bolt transmits its own WiFi.
