120mbps During The Day / 5mbps at night

Network congestion can cause speed degradations at night when everyone is on the internet. However, is it reasonable to see a 120mbps become 5mbps at night? In my home there are no « additional » users at night. The slowndown would need to be from external.

Any tips, unsure of what I can do about this.

    Not even close to normal.

    Are you sure that no one has hacked your WiFi ? I don't use the Fizz modem WiFi, but I think if you log into the modem ( user: cusadmin / pass: your wifi password), you should be able to see what devices are connected. Do you recognize them all ? You can even try changing the WiFi password. Using the Fizz app on your cellphone is the easiest way, but if you are logged in with a PC, you can do it from the wireless section in the menus.

    Videotron network splits areas quite quickly if there is such congenstion. I get 0 difference between day an night.

    Just as a Test, if you have a PC which can be connected to Ethernet directly, try disabling the WiFi on the router for a quick test (from the settings), and try seeing if a hardwired PC also has the same issues.

    Otherwise, you can contact Fizz customer service and see if they can check your line stats. It should be clear if there is any congestion.

    Hello Kai O.,

    I am sorry to hear about this situation. 
    I have verified your connection and it seems you are using a personal router.  
    Please try restarting both your router and our modem and test the connection again. 
    Some of your signals are also fluctuating in the past few days.
    Here you can find some manipulation you can try: https://fizz.ca/en/faq/my-wi-fi-network-slow-how-do-i-make-it-faster
