Yep, one of the changes was that the wifi toggle was abolished ... I loved that widget! One option as Ann154 pointed out is to use the power control widget. Another is to use a settings shortcut, i.e.,
long-press 'settings shortcut' and move wherever you want it on your home screen
a menu will pop up; scroll to the bottom and choose 'wi-fi'
A person could also try a third party widget from the Play Store. I know CurveFish made a WiFi toggle widget that I used ages ago.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
