CM 600 Frequently Dropping Internet Connections - Time Warner Internet

#1
This question is about "CM 600 Frequently Dropping Internet Connections", with Time Warner Cable internet and apps. I recently purchased the CM600 to upgrade the SB1690 from spectrum. I am frequently getting connection dropouts. A tech was recently at my house for over an hour performing some rewiring cable lines so everything should be good in that regard. I have contacted support and all the reccomend is me restarting my modem and router. I shouldn't have to do it 4 times a day in order for my internet to work. I am pretty tech savvy so any feedback would be appreciated. Thank you.
