My Wi-Fi network is slow. How do I make it faster?

The speed of a wireless connection can be affected by several factors.
It is normal for the speed of a wireless connection to vary depending on, among other things, distance to the Wi-Fi modem, technology used by the devices, and Wi-Fi interference.

  1. Make note of the various sources of attenuation of your Wi-Fi signal

    The waves in your Wi-Fi network may be attenuated by various obstacles and sources of interference, causing speed drops and partial or complete disconnections of your internet connection.


    Sources of interference include:

    • Nearby Wi-Fi networks
    • Surveillance cameras
    • Baby monitors
    • Microwave ovens
    • Etc.


    Obstacles to Wi-Fi waves include:

    • Construction materials (concrete, aluminum, etc.)
    • Heated flooring
    • Mirrors
    • Windows
    • Etc.


    If you are unable to change your environment to limit sources of Wi-Fi signal attenuation, it would be better to use a network cable (RJ45).

    A cable is included in the original box of your Fizz Wi-Fi modem.

  1. If you have only one device, make sure you test it with other websites, browsers and apps

    If the low speed is limited to one browser, one website or only one application, uninstall the browser or application from your device.

    If the situation remains unchanged after you reinstall the browser or application, consult support for this particular product.

  1. Do some speed tests

    Perform some speed tests using the Fizz Wi-Fi app. This app is available for free on Google Play Store and Apple Store.


    AppApple AppAnd


    Do multiple tests with different devices and at multiple locations around your home.

    Compare the results obtained at the downstream (Download) and upstream (Download) speeds of your Fizz Home Internet plan.

    If possible, also a speed test with a device plugged in using a network cable (RJ45) directly into the Wi-Fi modem.

    You can also perform a speed test using any website or app of your choice.


    Make sure you choose a speed test that uses a local server.

    Some sites only offer test servers located overseas. It could skew your results.

  1. Make sure your equipment is capable of reaching the desired speed

    Each subscribed device has a Wi-Fi standard. This standard represents the maximum speed that the device can reach.


    Here is a list of Wi-Fi standards and their approximate speed:

    Standard Frequency Maximum speed Reach Congestion Bandwith MiMo Supported Year of appearence
    802.11a 5 GHz 25 Mbps Weak Low 20 MHz No 1999
    802.11b 2.4 GHz 5 to 6 Mbps Acceptable High 20 MHz No 1999
    802.11g 2.4 GHz 20 to 25 Mbps Acceptable High 20 MHz No 2003
    802.11n 2.4 GHz 30 to 110 Mbps Good High 20 or 40 MHz Yes 2009
    802.11n 5 GHz 50 to 180 Mbps Good Low 20 or 40 MHz Yes 2009
    802.11ac 5 GHz 90 à 400 Mbps Good Low 20, 40 or 80 MHz Yes 2014


    Standards A, B and G are now obsolete based on average use.


    A Wi-Fi network can be compared to a highway. Devices that use obsolete standards are like a vehicle that slows down an entire lane.


    Different devices supporting the same Wi-Fi standard may not all have the same maximum speed.
    Only the latest, state-of-the-art devices will be able to reach maximum speeds.

    Consult the manufacturer’s datasheet to see which standard your device is using.

    If the band steering function on your Wi-Fi modem is turned off, in most cases it’s preferable to manually select the 5GHz Wi-Fi frequency band.

  1. Restart your Wi-Fi modem


    1. Unplug the power cable on your Wi-Fi modem.
    2. Make sure all the lights on the modem are off once you have unplugged it.
    3. Wait ten (10) seconds.
    4. Plug your modem back into the electrical outlet. Expect a three (3) minute delay to allow your devices to reconnect to the Wi-Fi network.


    It is more effective to restart your Wi-Fi modem by unplugging its power cable instead of pressing its power button.


  1. If allowed by your device, connect to the 5 GHz Wi-Fi frequency

    Your Fizz Wi-Fi modem uses by default the frequency band steering technology. When this function is disabled, the Wi-Fi modem will display two (2) frequency bands, 2.4 GHz and 5 GHz. Manually select the 5 GHz from your devices.


    The modification of this option is possible thanks to the mobile application Fizz Wi-Fi:


    1. Choose: ''My Wi-Fi''
    2. Select your Wi-Fi network
    3. Select: ''Advanced Settings''
    4. Band Steering ''On/Off''

    The Fizz Wi-Fi app is available for free at various online stores (Apple Store and Google Play Store).


    This change can also be applied through the Wi-Fi modem user interface:


    1. Log in at: from the web browser of any device.

    2. Log in using the following information:

    • Username: cusadmin
    • Password: xxxxxxxx (Password you chose during initial setup)

    3. Go to the next section to apply changes:

    Wireless → General Settings → 5GHz → Band Steering (Disable)


    If you do not remember the password you entered during setup, press and hold the "Reset" button behind the modem to reset your Wi-Fi modem back to its factory settings.

  1. Consider adjusting your Fizz Home Internet plan to better meet your needs

    Reduced speeds are possible if your plan is not sufficient for your needs, or if several people are using your Wi-Fi network simultaneously.

    Some devices connected to your Wi-Fi network could also be using your network in the background, for example:

    • Operating system updates
    • Photo albums that are syncing
    • Cloud hosting
    • Etc.


    Here are some examples of average usage:

    Type of service Bandwith Data Consumption
    • UHD 4K: 6 to 10 Mbps
    • 1080p: 4.5 Mbps
    • 720p: 2.5 Mbps
    • 480p: 2 Mbps
    • UHD 4K: 2.7 to 4.5 GB/hour
    • 1080p: 2 GB/hour
    • 720p: 1.1 GB/hour
    • 480p: 450 MB/hour
    Music streaming
    • Audio quality: 320 Kbps
    • Audio quality: 96 Kbps
    • Audio quality 320 Kbps: 50 MB/hour
    • Audio quality 96 Kbps: 44 MB/hour
    Video streaming
    (Other than YouTube)
    • High video quality: 5 Mbps
    • Medium video quality: 2.5 Mbps
    • Low video quality: 256 Kbps
    • High video quality: 2 GB/hour
    • Medium video quality: 1 GB/hour
    • Low video quality: 115 MB/hour

    Video conference

    (Skype, Facetime and others)

    • 7 people: 8 Mbps
    • 5 people: 4 Mbps
    • 3 people: 2 Mbps
    • 7 people: 8 Mbps: 3.6 GB/hour
    • 5 people: 4 Mbps: 1.8 GB/hour
    • 3 people: 2 Mbps: 900 MB/hour


    The information provided here above is when the wireless connection is optimal, without interference or congestion.

  1. Restore your Wi-Fi modem to its factory settings

    IMPORTANT: This will reset any changes that have been made to your Wi-Fi modem settings to date. You may also need to reconfigure your devices’ Wi-Fi settings (network name, password, etc.).


    Using a small, sharp object, press the modem’s reset button for 10 seconds.

    Once your modem has restarted, follow the same instructions you used when you initially installed it.


    Reminder: The default username (Default Wi-Fi network) and password (Default key) for your Wi-Fi network are written on a sticker on the back of your Wi-Fi modem.
