Wifi drops - Time Warner Internet

This question is about "Wifi drops", with Time Warner Cable internet and apps. After a few days of monitoring, I am finding that most of my drops are wifi only. When they happen, ALL devices drop. I can be sitting immediately next to the router and have no wifi. Sometimes, the wifi even insists I am giving it the wrong password when I am not. I also can't go to the router through the IP address.

I need this to be fixed.

Can this be related to signal strength? Where do I go from here with support?

Wifi drops?
