I've put the modem and my own router in bridge mode with great speed but in the last few days, speed has been extremely slow (400 to almost 50). It will be okay if i'm next to the modem but if i am 10 feet away, the speed begins to slow down.
I've also tried unplugging and vice versa.
Hi
It can be a problem with the signal from the coaxial cable. I will personally try to connect my computer directly to the modem and see if it will change something to do so, turn off the modem, disconnect the router, connect your computer at the place of the router, turn on the modem after 4-5 minutes try the speed.
If you have the same result, contact the support in order to test the cable signal and if they find a problem they will send a tech to resolve it,

, and click on the green bubble on the bottom right of the page in order to chat with them to find the right solution for you.

A coaxial signal checking is necessary
Could check if you are on 5ghz frequency too
Hello phar4oh,
We are sorry to hear about the situation encountered with your internet speed.
After making the necessary verifications into our tools we were able to see that your home internet plan is active, signals optimal and the modem is provisioned with the correct speed therefore your connection should work properly.
Given the fact that you are using your own router, as the users already suggested, it will be needed for you to disable it and use only the Fizz modem, at least for 48-72 hours in order to test the speed.
Since the wi-fi option is disabled, we are not having visibility over it into our tools in order to assist you properly.
If the restarting of both ( modem and router) did not help, you can try to factory reset the Fizz modem and configure it like first installing it.
To factory reset, you will need to press the small reset button from the back of modem with a sharp object, for at least 10 seconds, then wait for it to be back online.
After that, use the steps from here: https://fizz.ca/en/faq/how-install-my-wi-fi-modem
Our customer service agents are available at any hour therefore in case you need assistance, you can reach them.
For that, you can access this link: https://fizz.ca/en/support
Have a great day.
