Help lenovo ideapad tablet A2109A

Hi. My Lenovo Tablet A2109A will no longer connect to wifi. It says turning on wifi but nothing ever happens. I cant even move the tab that says turn on wifi. I have been able to use my tablet and connect to my wifi since I've had it. I'm not real tech savvy but I can follow directions and am able to figure most things out. (obviously not this) :) Any help would be greatly appreciated. Thanks.
