Bufferbloat Fix: Router Queues and Why Upload Ruins Your Game
Your internet can be fast and still feel terrible for gaming. The main culprit is often bufferbloat: large queues that build up under load and add big latency spikes.
What Bufferbloat Is
- Routers and modems buffer packets when links are busy.
- If queues are too deep, latency increases massively under load.
- Uploads are the usual trigger because upstream is smaller than downstream.
What It Feels Like
- Sudden heavy input and delayed reactions during uploads.
- Rubber-banding or hit registration feeling off.
- Voice chat breaks up when someone starts a big transfer.
Practical Fix Order
- Identify load spikes by testing while uploading and downloading.
- Reduce or schedule background uploads during gaming hours.
- Use a router configuration that controls queues (sane queue management).
- If your ISP gear is the bottleneck, bridge to a better router or replace it.
The Rule
A stable connection beats a fast connection for gaming feel. Fix latency under load first, then chase speed.
