How do I turn off WLAN on my internet router

[Ahmad9]

Just switched to Fido and the internet doesn't reach to the basement so I put an Ethernet cable to another modem and in the basement the wireless internet works off the other modem coming from the new Fido. At night we turn off wlan so the kids don't stay up on the wifi but Ethernet connected cable still working, my question is how do I turn off wlan on my new Fido router? It's CNG3U model.
