Why wireless and wired speed tests may vary

Last updated on Nov 21, 2024

Networks often deliver variable performance due to several factors. If you’re experiencing slower-than-expected speeds, here’s what to consider:

  1. Signal Strength: The distance from your router and physical barriers like walls or furniture can reduce signal strength and impact performance.

  2. Interference: Wireless networks can experience interference from other devices (e.g., microwaves, cordless phones) or neighboring Wi-Fi networks, especially on the 2.4 GHz band. Modern routers broadcast on both 2.4 GHz and 5 GHz to help minimize this.

  3. Device Performance: The age, quality, and wireless standards supported by your device (e.g., laptop, phone, tablet) can significantly impact the speed it can achieve.

  4. Router Placement: Positioning your router centrally in an open area can help ensure even coverage throughout your space. Avoid placing the router near metal objects or in enclosed spaces.

  5. Testing Variance: Speed test results can vary depending on the testing server and whether the device is connected via Wi-Fi or Ethernet.

For the most accurate speed tests, use a wired Ethernet connection whenever possible.


Steps to Reboot Your Cable Modem

Rebooting your cable modem can resolve many speed-related issues. Here’s how:

  1. Power Off: Unplug the modem from its power source.

  2. Wait: Keep it unplugged for at least 30 seconds to allow a full reset.

  3. Reconnect Power: Plug the modem back in and ensure all cables are securely connected.

  4. Wait for Reconnection: Allow 2–3 minutes for the modem to reconnect to your internet service provider (ISP).

Once rebooted, retest your speeds to check for improvement.


Testing Internet Speeds

When testing your internet speeds:

  • Use a speed test tool like speedtest.net.

  • Perform tests from multiple devices to identify if the issue is isolated to one device or affects the entire network.

  • For wireless tests, try standing closer to the router for stronger signal strength.


Expected Speeds

Confirm your subscribed internet speeds with your ISP. For example, if your plan is for 200 Mbps download and 10 Mbps upload, you should expect speeds close to these under optimal conditions. Note that wireless speeds may be lower due to the factors described earlier.
