ISP Speed vs. Wi-Fi Speed

The difference between the speed your ISP delivers to your modem (ISP speed) and the speed you experience on your device over Wi-Fi (Wi-Fi speed). Most "slow internet" complaints are actually Wi-Fi problems.

What It Means

Your ISP delivers a certain speed to your modem — this is what you are paying for. Between the modem and your device, speed can be reduced by: router quality, Wi-Fi standard (Wi-Fi 5 vs 6 vs 7), distance from router, walls and interference, number of connected devices, and 2.4 GHz vs 5 GHz band. To diagnose: run a speed test plugged directly into your modem via ethernet. If wired speed matches your plan but Wi-Fi is slow, the problem is your home network, not your ISP. An estimated 70% of speed complaints are Wi-Fi issues.

Internet Speed Test
A tool that measures your real-world download speed, upload speed, and latency by transferring data to and from a nearby test server. Results vary by test methodology and conditions.
Speed Test Accuracy
The reliability of speed test results depends on testing conditions, device capabilities, connection type (wired vs. Wi-Fi), and the test server location. No single test gives a complete picture.
Single-Thread vs. Multi-Thread Speed Test
Two different speed test methodologies. Single-thread tests measure one connection stream (more realistic for typical use), while multi-thread tests use many parallel streams (showing maximum capacity).
Peak vs. Off-Peak Speeds
Internet speeds that vary by time of day due to network congestion. Peak hours (7-11 PM) typically show 20-40% slower speeds than off-peak on cable and fixed wireless connections.
