These three problems feel similar but have different fixes. Knowing which one you have saves a lot of time.- Packet loss: Data never arrives, so the server may cut you off.
- Jitter: Your ping jumps up and down, which causes stutter and sudden drops.
- High ping: Every action is delayed, which makes combat feel heavy.
How Can You Test Your Route?
