One thing we can test with and can easily be reverted if it doesn’t help is changing the power save feature for your wireless.
Please open a terminal and run this command:
sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
This will change the power save setting from 3 to 2. Then reboot your Framework, run iwconfig again and it should display Power Management:off
This may help, it may not help at all. But I’ve seen examples where it has and does provide a bit truer performance.
If it does nothing, we can always change it back with:
sudo sed -i 's/wifi.powersave = 2/wifi.powersave = 3/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
