Kasaco mx780 16gb tablet will not connect to my wifi network

I've tried every trick online to get my new kasaco 10.1 inch 26gb tablet to connect to my wifi network. It just keeps displaying can not connect to WiFi then displays the network name as saved. I know that there are alot of people with the same tablet having the same issue. Someone on Amazon wrote “ when I first got the tablet the launcher wasn't set up, but after I set the launcher up it connects to WiFi right away and haven't had any issues since the launcher was installed. “ I'm confused what did he means by s launcher because that sounds like it might be the fix I need. Please if some decent human being out there see my question, could you take a few minutes and help out a fellow decent human being like yourself, but I'm probably not as smart if your assisting me with this GD tablet hooked up to my wifi so I can give it to my son and he can give me back my faithful Nexus 7 2013 edition tablet.

PLEASE HELP !!!
