# Arch Linux Intel AX211 Wifi X1 Carbon (Gen 10)

### wifi (iwlwifi)

Had to configure the following to keep the wifi stable. For information about the parameters, see the [Parameters](#Parameters) section.

cat /etc/modprobe.d/iwlwifi.conf 
options iwlwifi 11n_disable=8
options iwlwifi uapsd_disable=1
options iwlmvm power_scheme=1 

### The error I was getting
