Network Optimization Guide (Gaming/Streaming)

How I Reduced Gaming Latency by 192ms on a Locked ISP Network 🔗 Project Repository GitHub: https://github.com/SoumyaKhaskel/Network-router-optimization.git Most gaming setup posts focus on GPU, RAM, or CPU tuning. This one is about the part people usually ignore: the network path. I worked on a single NAT home network with an ISP-locked ONT and limited router access, then documented every change with before/after testing. The goal was simple: reduce latency spikes, stabilize the connection, and improve responsiveness for CS2 and Valorant. What I was dealing with The setup had a few hard constraints: ISP-locked main gateway No custom firmware support on the existing router hardware No proper port-forwarding control from the admin panel Windows 11 Home, so no Group Policy editor for QoS Bufferbloat on the download side under load That meant the fix had to be practical, measurable, and done mostly from the OS side. Baseline testing first Before changing anything, I measured the network.
