No internet connection at all when Wifi signal becomes average (Xiaomi 14 houji)

There appears to be a bug (specific to houji?) with Wifi connection

Initially I wasn't aware of this, but a user from a telegram group asked me to step away from my router a bit to see if the connection becomes unavailable when the signal is a bit weaker. And as you can see on the screenshot, no internet.

I am on HyperOS by xiaomi.eu (initial release).
