• Fiber-to-the-home: symmetric by design, lowest jitter, and the most reliable under real-world load
• Coax, copper, and fixed-wireless: competitive download figures, but upload and peak-time performance vary by neighborhood and time of day
• What "good" looks like: a wired test in the 80–95% range of your advertised speed, with upload in the same ballpark your plan promises

Speed Test Tips for Philadelphia, PA 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
