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.

Same issue !!! no one will believe cause its normal for many mobiles to pick 72mbps link on 2.4ghz link ... But M51 use to pick 150mbps link on my 2years old 2.4ghz router and I used to get 70mbps on my 70mbps plan until One UI 3.1 ... Picture attached check ... Even my Asus Laptop vivobook 14 i5 picks up 70mbps over my old tp link router .... Screenshot_20210628-110526_Speedtest_59936.jpgScreenshot_20210628-110606_Speedtest_59937.jpg

True... Even this M40 used to pick up 150mbps link speed before One UI 3.1 update. And I used to get roughly 80 mbps when near to router on speedtest dot net on my 200mbps plan and now after update I am getting hardly 40 to 50 mbps.

I have Samsung M40 and A50 both link speed reduced to 72mbps after One UI 3.1 update. My poco F1 picks link speed of 144mbps and gives actual speed of about 70mbps on speedtest dot net.
