Arris Sb8200 - dual IP address

Hi guys,

can someone help me with an issue I'm currently facing?

issue:

due to COVID, I have been working from home and so have my siblings. Due to the nature of my job, I'm constantly on zoom meeting, transferring heavy data, and being a parent of young kids, who's studying from home, constantly streaming video, and playing games. I'm facing lag in my internet speed and time to time get kicked out of meeting due to signal issues.

Currently, I have a smart netgear advanced switch installed for my work and personal machines and have google nest WiFi system for my WiFi needs currently on 1000mbps plan). Most recently, I have been running into this problem so much that my video and calls have been dropping a lot more. I'm finally given a last warning by my office. So I was doing research and trying to find a solution for my problem. Based on my research, I purchased a Arris SB8200 modem because they advertised that I can get two up adress from my isp. I called Comcast but they said they don't offer that, I checked the pdf file (based on other forms here) and it's not offered in my area.

I was wondering (praying) someone here could help me out and find me a better solution?
