My DELL laptop has been giving me issues with the following line: “wlp0s20f3: Limiting TX power to 30 (30 – 0) dBm as advertised by xx:xx:xx:xx:xx:xx” which causes a short drop in connectivity. I found the following solution:
Edit /etc/default/crda and add REGDOMAIN=NL
Edit/etc/modprobe.d/iwlwifi.confand append the following:
# Set TX power limit
options iwlwifi txpower=20
