Hi guys i have this extreme low wifi sensitivity in fedora 38 using a dell inspiron 5548
Other devices i have run totally normally, and im using a usb-wifi card and it works fine,
its just the built in antenna that doesn’t find o very weakly finds any network.
Please help me to find a solution to improve the sensitivity or whatever causes the non detection of wifi networks
I will paste some info
