What Speeds to Expect in St. Louis, MO

Typical measured speeds for St. Louis, MO residents: 300 Mbps – 2 Gbps. For the true ISP-side number, test over Ethernet; Wi-Fi introduces a separate stack of variables (signal strength, channel congestion, client radio) that can skew results by 10-30%.

• Fiber connections: symmetric upload and download, lowest latency, and the most stable performance under peak load — ideal for remote work and cloud workflows
• Cable, DSL, and fixed-wireless: usually fast download but slower upload, and more likely to dip 20-40% during 7-10 PM peak hours on shared local segments
• Benchmark against your plan: a healthy wired result should land within 80-95% of your advertised speed; anything consistently lower is worth flagging with your ISP
