TP Link T2U Plus 未连接也不显示任何网络（24.04）

谢谢你的帮助，我发现驱动程序中的 .conf 有问题，我改变了一些值，现在它可以正常工作了。.conf 文件（因为我是新手，所以我留下了评论，它们很有帮助）：

# /etc/modprobe.d/8821au.conf
#
# Purpose: Allow easy access to specific driver options.
#
# Edit the following line to change, add or delete driver options:
#
options 8821au rtw_led_ctrl=1
#
# Note: The above `options` line is a good default for managed mode. Below
# are examples for AP mode. Modify as required after reading the documentation:
#
# Band 1 (2.4 GHz)
#options 8812au rtw_switch_usb_mode=2
#
# Band 2 (5 GHz)
#options 8812au rtw_switch_usb_mode=1 rtw_vht_enable=2 rtw_dfs_region_domain=1 rtw_country_code=US rtw_power_mgnt=0
#
# After editing is complete, save this file (if using nano: Ctrl + x, y, Enter)
# and reboot to activate the changes.
#
# Note: hostapd information is located at the end of this file.
#
# Documentation:
#
# -----
#
# Log options ( rtw_drv_log_level )
#
# 0 = NONE (default)
# 1 = ALWAYS
# 2 = ERROR
# 3 = WARNING
# 4 = INFO
# 5 = DEBUG
# 6 = MAX
#
# Note: You can save a log file that only includes RTW log entries by running
# the following in a terminal:
#
# sudo ./save-log.sh
#
# Note: A log option greater than 1 must be set. The name of the log
# file will be `rtw.log`.
#
# -----
#
# LED options ( rtw_led_ctrl )
#
# 0 = Always off
# 1 = Normal blink (default)
# 2 = Always on
#
# -----
#
# VHT options ( rtw_vht_enable )
#
#  0 = Disable
#  1 = Enable (default)
#  2 = Force auto enable (use only for 5 GHz AP mode)
#
# Notes:
# - A non-default setting can degrade performance greatly in managed mode.
# - Option 2 allows 80 MHz channel width for 5GHz AP mode, such as when
#   you are using hostapd.
#
# -----
#
# Power options ( rtw_power_mgnt )
#
# 0 = Disable power saving
# 1 = Power saving on, minPS (default)
# 2 = Power saving on, maxPS (not recommended for AP mode)
#
# -----
#
# DFS Options ( rtw_dfs_region_domain )
#
# 0 = NONE (default)
# 1 = FCC
# 2 = MKK
# 3 = ETSI
#
# Notes:
# - Activates DFS channels in AP mode.
# - DFS FCC 80 MHz channels for hostapd: 52(58), 100(106), 116(122) and 132(138)
# - 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.
#
# -----
#
# Wireless Mode options ( rtw_wireless_mode )
#
# 1  = 2.4GHz 802.11b
# 2  = 2.4GHz 802.11g
# 3  = 2.4GHz 802.11b/g
# 4  = 5GHz 802.11a
# 8  = 2.4Hz 802.11n
# 11 = 2.4GHz 802.11b/g/n
# 16 = 5GHz 802.11n
# 20 = 5GHz 802.11a/n
# 64 = 5GHz 802.11ac
# 84 = 5GHz 802.11a/n/ac
# 95 = 2.4GHz 802.11b/g/n 5GHz 802.11a/n/ac (default)
#
# -----
#
# Country Code options ( rtw_country_code )
#
# Note: Allows the Country Code to be set in cases where it is unable to
# be obtained otherwise.
#
# URL: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2
#
# Example for the US: rtw_country_code=US
# Example for Panama: rtw_country_code=PA
# Example for Norway: rtw_country_code=NO
# Example for Kuwait: rtw_country_code=KW
# Example for Taiwan: rtw_country_code=TW
