Why is my internet slowing down to 25% of its usual speed at random intervals?

Hi Fizz and Fizz users,
For the past week, my internet has been slowing down to very slow speeds at random moments during the day. Sometimes it will be the correct 12-15 mbps then out of nowhere it will go down to 2-5 mbps for 10-15 minutes. Upload speed is not affected. I have tried unplugging the modem and replugging it. Thank you!

    Hi Adam,
    I understand and I'm sorry for the inconvenience you're currently experiencing.
    Would you kindly please unplug the coaxial cable from the coaxial outlet and the modem respectively, wait for about 30 seconds, then plug it back in the outlet first and then in the modem, then restart it?
    Also, please perform a factory reset of the modem by using a sharp object to press on the small button in the orifice behind the modem for 15 to 20 seconds, then let the modem reboot itself and test the connection.
    Following this, please change the connection bandwidth from 2.4GHZ to 5GHZ as shown here below:
    The modification of this option is possible thanks to the mobile application Fizz Wi-Fi:
    Choose: ''My Wi-Fi''
    Select your Wi-Fi network
    Select: ''Advanced Settings''
    Band Steering ''On/Off''
    This change can also be applied through the Wi-Fi modem user interface:
    1. Log in at:192.168.0.1 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)
    I checked on your account and on your connection signals where I can see that they are within the optimal parameters, with no package loss or broadcast congestion.
    There is also no incident or maintenance work being performed in the area that could've caused the disruption.
