Android 11 wifi issues on A71 & A72

I upgraded the firmware of my SM-A715F-XFA device over the weekend.

I have found that the wifi is not working correctly regarding speed, I changed the channel width to 40MHz 2.4Ghzon the router and the speed of the device remained at 72Mbps, however when the device was on Android 10 the speed of the wifi on the 40MHz channel width reflected 150Mbps.

I have also acquired a SM-A725F-XFA device Android 11 and the speed reflects 72Mbps on both the 20 and 40 MHz channel width.

This is a firmware problem and Samsung in conjunction with Google need to repair this as soon as possible.

Reason for purchasing Samsung devices is that we have a limited scope of devices available in this region.

This does not happen on the 5 Ghz channel

 

SAMSUNG FIX YOUR FIRMWARE AND DONT BLAME OTHER ISSUES

Hey. Did you fix the wifi 2,4 ghz 20 mhz issue?

Got an A32 yesterday and also here at max 72 mbit on 2,4 ghz with 20 mhz.

All other devices at home on 2,4 ghz 40 mhz and 150 mbit with my fritzbox.

Searched the whole day but couldn't find anything.

Is it the Android 11 software or the Galaxy A series?

Thank you for your help,

Markus

Yesterday a software upgrade has blocked my phone with continuous rebooting. When unlock phone and open something, the screen freezes. And 5 seconds after the phone reboot so again.

If I turn off WiFi problem stops. 

Problem seems to occur even if no WiFi is saved. Just switching on WiFi on main top switch makes phone reboot immediately. 

Software version is a725fxxs8fxe3 / foxm8fxe4 / fxxs8fxe3
