[Solved] Wifi connection dropping frequently

Wifi setup is using Network Manager and wpa_supplicant.

steps I tried so far:

To change the DHCP client backend, set the option main.dhcp=dhcp_client_name with a configuration file in /etc/NetworkManager/conf.d/ from
DHCP client
Disabling MAC address randomization
wifi.scan-rand-mac-address=no

this is a recent problem, but since I don't use the wifii connection very often on my machine I haven't noticed it until now, I just thought that my wifi connection was not that good, but the problem seems to be happening only on the machine running arch.

it happens mainly every time when a process that requests a lot of packets is running, like updating the system for example. the internet speed drops and waits for a connection to be reestablished with the router automatically, if I run nmcli connection up, the connection is established quickly again.

wifi-card:
