How do I disable "Ready to connect when the network quality improves"?

Hi, I'm currently having trouble with my wifi connection repeatedly being disconnected and saying "Ready to connect when network quality improves" despite being at full strength and quite stable (from my laptop).

I have tried already going to the wifi settings and intelligent wifi settings and disabling most of the options however am not able to turn off the first one called Switch to mobile data as I am roaming at the moment.

Does anyone know a fix for this? Thanks!
