[Bloat] Question about Buffer Bloat and Verizon Fios

[games at djlatino.com]

I’m excited that I just got this to implement in my home. 
I installed cerowrt 3.10.50-1 on my Netgear WNDR3800. 

My question is, will this work with verion fios?
Reason is Verizon has a combo router/modem. 
I’m not sure having if I connect PS4 > Netgear > Verizon Fios will benefit buffer bloat. 
Maybe my setup is incorrect. 

I have been struggling with latency while playing on my PS4 kids streaming on youtube, and wife surrfing and hoping this will help. 
I do understand there might be issue with certain games net coding but hopeing to eliminate as much as posible. 
Any suggestions would be appreciated.
