Baby monitor interference

Since we switch to Fizz, my baby monitor is not working properly. I really have issues with the signal. Its not a wifi monitor. It look like if the wifi was impairing with the monitor's signal.
I have segmented my network with a 2.4 and a 5ghz already.
Before, the routeur was in the room next to my monitor and there were no problem. Now its literrat at the opposite of the home (basement and opposite position of the house).. again my monitor is not using the wifi network, but its own signal.
Anyone has an idea?
