How to Test Business Internet Speed, Latency, and Packet Loss

Slow internet can be worse than a full outage because it is harder to diagnose. The best way to troubleshoot business internet performance is to measure speed, latency, and packet loss in a consistent way. These three numbers explain most issues that affect calls, video meetings, and cloud apps.

This guide shows how to test business internet speed and stability, interpret the results, and document the evidence you need for your ISP or IT provider.

What the three metrics mean

• Speed is your download and upload bandwidth. It affects file transfers and streaming.
• Latency is the time it takes data to travel to a destination and back. It impacts calls and app responsiveness.
• Packet loss is the percentage of data that never arrives. Even small loss can cause jitter and dropped sessions.

Step 1: Run a speed test on a wired connection

Connect a computer directly to the router or modem with Ethernet. Run a trusted speed test two or three times. Use the average result. This gives you the most accurate baseline for your business internet connection.

Step 2: Run the same tests on Wi-Fi

Repeat the test on Wi-Fi from a normal working area. Compare the results with the wired test. If Wi-Fi is significantly slower, the issue is likely the access point, interference, or device distance.

Step 3: Check latency and packet loss

Use a ping or network test tool to measure latency and packet loss to a well known host. Run the test for 30 to 60 seconds. If latency is high or packet loss appears, that explains choppy calls and slow cloud apps.

Step 4: Test at different times of day

Business internet performance can drop during peak hours. Run the same tests in the morning, midday, and evening. This shows if congestion is the real problem.

Step 5: Record your results

Document the date, time, location, and results. Screenshots are useful. When you contact your ISP, these records help them validate the issue faster and may qualify you for service credits.

What good numbers look like

There is no universal number, but many businesses want latency below 50 ms, packet loss close to 0%, and speed consistent with the plan they pay for. If you consistently fall short, it is time to troubleshoot hardware or escalate with your ISP.
