Will changing from 150 down to 1 gigabit down fix my packet loss/latency issues?

I'm pretty frustrated right now with intermittent latency issues and packet loss. I can't use voip to make my meeting calls or play online video games without lag. I've replaced basically all of my hardware, and there is still an issue. I've also had a tech come out. 

Will increasing my speed give me more bandwidth to fix these issues?
