Having trouble with Wi-Fi connectivity on my i7 laptop running Manjaro—what could be the cause and solution?

Hi,

It there are glitches with wifi connection, first try disabling powersave and Mac randomization. Seem to be one main source of wifi headaches:

RTL8822CE Instability even with newest kernel

You can try two workarounds. Turn off wifi power save first. Create .conf file: sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf And copy these two lines inside it: [connection] wifi.powersave = 2 If the issue remains, turn off Mac Randomization. Create .conf file: sudo nano /etc/NetworkManager/conf.d/disable-random-mac.conf Copy these two lines inside: [device] wifi.scan-rand-mac-address=no Hope this can solve your problem.
