    Why Test Your Internet Speed?

    Knowing your internet speed helps you:

    • Determine if slow performance is your internet or something else
    • Check if you are getting what you pay for from your provider
    • Troubleshoot video call quality issues
    • Understand if your connection can handle cloud applications
    • Provide useful information when contacting IT support

    How to Run a Speed Test

    Using Speedtest by Ookla

    • Go to speedtest.net in your browser
    • Click the large Go button
    • Wait about 30 seconds for the test to complete
    • Note your results

    Using Fast.com

    • Go to fast.com in your browser
    • The test starts automatically
    • Wait for the download speed to appear
    • Click Show more info for upload speed and latency

    Tips for Accurate Results

    • Close other applications using the internet (especially video streaming)
    • Use a wired connection if possible (WiFi can reduce speeds)
    • Test at different times of day (speeds vary with network congestion)
    • Run 2-3 tests and average the results

    Understanding Your Results

    Download Speed

    This measures how fast data comes TO your computer. Affects:

    • Loading websites and emails
    • Downloading files and attachments
    • Streaming video calls (receiving)
    • Using cloud applications
    What speeds mean for business:
    • Under 10 Mbps: Struggles with video calls and cloud apps
    • 10-25 Mbps: Adequate for basic business use (1-2 users)
    • 25-50 Mbps: Good for small teams with regular video calls
    • 50-100 Mbps: Comfortable for 5-10 users with heavy cloud use
    • 100+ Mbps: Excellent for larger offices or data-heavy work

    Upload Speed

    This measures how fast data goes FROM your computer. Affects:

    • Sending emails with attachments
    • Uploading files to cloud storage
    • Video calls (your video quality to others)
    • Backing up data
    Typical upload speeds:
    • Under 5 Mbps: Video call quality may suffer
    • 5-10 Mbps: Adequate for most business tasks
    • 10-20 Mbps: Good for regular video conferencing
    • 20+ Mbps: Excellent for uploading large files

    Ping (Latency)

    This measures delay in milliseconds (ms). Lower is better. Affects:

    • Video call responsiveness
    • VoIP phone call quality
    • Remote desktop responsiveness
    • Real-time applications
    What ping times mean:
    • Under 20ms: Excellent, no noticeable delay
    • 20-50ms: Good for most business applications
    • 50-100ms: Acceptable but may notice slight delays on calls
    • Over 100ms: May experience lag on video calls and VoIP

    Jitter

    Variation in ping time. High jitter causes:

    • Choppy video calls
    • Audio cutting in and out
    • Inconsistent performance
    Acceptable jitter: Under 30ms for business use

    What Speeds Do You Need?

    For Different Activities

    | Activity | Minimum Download | Recommended | |----------|-----------------|-------------| | Email and browsing | 5 Mbps | 10 Mbps | | Video calls (1 person) | 5 Mbps | 15 Mbps | | Video calls (multiple) | 15 Mbps | 25 Mbps | | Cloud applications | 10 Mbps | 25 Mbps | | Large file transfers | 25 Mbps | 50+ Mbps |

    Per Person Rule of Thumb

    For a shared office connection, estimate 10-15 Mbps per person for comfortable business use with cloud applications and occasional video calls.

    Troubleshooting Slow Speeds

    If Speeds Are Lower Than Expected

    • Restart your modem/router - unplug for 30 seconds, plug back in
    • Test with a cable - WiFi loses significant speed
    • Check who else is using the connection - downloads or streaming affect everyone
    • Test at different times - peak hours may be slower
    • Check your plan - confirm what speeds you are paying for

    If Speeds Match Your Plan But Feel Slow

    • Your plan may not be sufficient for your needs
    • Consider upgrading your internet plan
    • Check if multiple devices are consuming bandwidth

    WiFi vs Wired Comparison

    Run tests on both WiFi and wired (Ethernet cable) connections:

    • If wired is much faster, the issue is WiFi signal or interference
    • If both are slow, the issue is your internet connection

    Recording Results for IT Support

    When reporting internet issues, provide:

    • Download speed (Mbps)
    • Upload speed (Mbps)
    • Ping/latency (ms)
    • Time of test
    • Whether you tested on WiFi or wired
    • What internet plan you pay for
    This information helps IT diagnose issues much faster.
