Bad Wi-Fi when i have bluetooth on?

I want to play fortnite on my cell phone and for that I connect my controller via bluethooth but then my Wi-Fi is very bad if i turn bluethooth out i have very good Wi-Fi.

Bluetooth runs around the corner with 2.45ghz, so to speak, using the same resources in competition, so a drop in performance is quite conceivable even if the capacity is relatively low with 750kB / s.

A permanent influence is of course unpleasant, but the use of multiple hardware on the smartphone also has its limits.
