    Why Check Internet Speed?

    Slow internet can make:

    • Video calls choppy
    • File downloads take forever
    • Websites load slowly
    • Cloud apps feel sluggish
    A speed test helps determine if your internet is the problem.

    Running a Speed Test

    Step 1: Close Other Programs

    For accurate results:

    • Close video calls
    • Stop any downloads
    • Close streaming video

    Step 2: Visit a Speed Test Site

    Go to one of these sites in your browser:

    • speedtest.net (most common)
    • fast.com (simple, by Netflix)

    Step 3: Run the Test

    Click the Go or Start button and wait about 30 seconds.

    Step 4: Read Your Results

    You'll see:

    • Download speed - How fast you receive data (most important)
    • Upload speed - How fast you send data
    • Ping - Response time in milliseconds

    Understanding Your Results

    Download Speed

    | Speed | Experience | |-------|------------| | Under 5 Mbps | Very slow, video calls will struggle | | 5-25 Mbps | Basic browsing OK, video calls may have issues | | 25-100 Mbps | Good for most office work | | Over 100 Mbps | Excellent |

    For Video Calls (Teams, Zoom)

    • Minimum: 1.5 Mbps download and upload
    • Recommended: 4 Mbps or higher
    • Group HD video: 8+ Mbps

    Ping

    • Under 20ms: Excellent
    • 20-50ms: Good
    • 50-100ms: OK
    • Over 100ms: May cause delays

    What If Speed Is Slow?

    Quick Fixes:

    • Restart your router - Unplug for 30 seconds, plug back in
    • Move closer to the router - If on WiFi
    • Use a cable - Ethernet is faster than WiFi
    • Check for other users - Someone streaming video?
    • Close bandwidth-heavy apps - Downloads, streaming

    Still Slow?

    Contact IT. The issue might be:

    • Your internet plan
    • Router problems
    • Network configuration
    • Building infrastructure

    Testing at Different Times

    Internet can be slower when:

    • Many people are online
    • During peak hours
    • Bad weather (for some connections)
    Test at different times to get a full picture.
