• 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 Jacksonville, FL Residents

• Test on Ethernet to establish a baseline without Wi-Fi interference
