#
|
|
# Purpose: Allow easy access to specific driver options.
|
|
#
|
|
# Warning: Some adapters based on the rtl8821cu chipset may require the
|
|
# `rtw_RFE_type` option to be set. If wifi or bluetooth does not work
|
|
# after driver installation, see the appropriate section in the below
|
|
# documentation.
|
|
#
|
|
# Edit the following line to change, add or delete options:
|
|
options 8821cu rtw_drv_log_level=0 rtw_led_ctrl=1 rtw_vht_enable=1 rtw_power_mgnt=1 rtw_dfs_region_domain=0
|
|
#
|
|
# After editing is complete, save this file (if using nano: Ctrl + x, y, Enter)
|
|
# and reboot to activate the changes.

# Notes:

|
|
# - For more information: https://en.wikipedia.org/wiki/List_of_WLAN_channels
|
|
#
|
|
# Note: An AP needs to listen on a DFS channel for a period of 60 seconds
|
|
# before transmitting on the channel. If any radar pulses are detected,
|
|
# the AP cannot use that channel and will have to try a different channel.

# set. It may be necessary to try different settings to determine
