Typical measured speeds for Detroit, MI residents: 200–1000 Mbps. 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

Speed Test Tips for Detroit, MI Residents

• Test on Ethernet to establish a baseline without Wi-Fi interference
• Run tests at both morning (off-peak) and evening (peak) hours — cable networks often slow significantly during prime time
• Check upload speed, not just download — upload is the limiting factor for video calls, live streaming, and cloud backup
• Run 3+ consecutive tests and note the minimum — your calls happen at real-time, not average performance
