The four typical cables attached to the Nokia ONT are fibre, power, ethernet and landline phone. In your case the T3200 is merely only a router. It's not the modem. Resetting the router is the last recommended troubleshooting step
Does the ONT have a red light on it? If yes, call Telus for assistance.
Are you connected through ethernet to the Telus router (T3200) or by wifi?
If ethernet, does your computer report any problems getting an IP address? Can you log in to the modem from an ethernet connected device?
If wifi, does your device show it is connected to your T3200? If you've reset it, it likely has the default network name and password printed on the sticker.
What happens when you try to open a browser? Any error messages?
Have you tried the Telus My Wi-fi app on your phone? Can it connect to your T3200?
If you open the My Wi-fi app and tap Network at the bottom, at the top it should say Modem (T3200). If you tap on that it will show the current status of it. If it shows as Online, tap the Speed test icon in the top centre and see what speeds it gives. If that works, then the T3200 is online and the problem potentially is at your end.
