My modem won't let me connect wirelessly - Time Warner Internet

This question is about "My modem won't let me connect wirelessly", with Time Warner Cable internet and apps. This started happenening to me a couple days ago. The modem does not have the wireless light on, and I couldn't connect to my devices. The only thing I can access the internet using the modem is to connect via Ethernet. It's fustrating for me because I use the internet to use Roku, Video games, etc. Can you help me with this, and do any of you have a solution to this?
