Wifi 2.4 GHz link speed after One UI 3.1 Update Samsung M40

[VivekGangani]

After One UI 3.1 update my wifi 2.4 GHz link speed doesn't go higher than 72 mbps, before update it was 150 mbps. Other devices on my network are getting 144 mbps link speed.

P.S. Wifi Router 2.4 GHz channel width is set to 40 MHz.
