TP Link T2U Plus Não conecta nem mostra nenhuma rede (24.04)

  • 772

Eu uso o Ubuntu 24.04, troquei do Windows porque fiquei puto com uma empresa multibilionária que não consegue fazer uma atualização adequada. De qualquer forma, eu tenho um TP Link, tentei todos os drivers que encontrei no GitHub, mas nada funcionou, reiniciei o NetworkManager várias vezes após cada instalação de driver. Ainda nada. Encontrei pessoas com o mesmo problema que consertaram com um driver que baixei e ainda tenho o mesmo problema. O sistema reconhece o adaptador, mas ele parece não se comunicar com o roteador? Se alguém puder ajudar, eu ficaria grato. A versão do kernel é 6.8.0.

EDIT: O problema era que o arquivo .conf do driver não estava configurado corretamente.

    Obrigado pela ajuda, percebi que o .conf estava ruim no driver, alterei alguns valores e agora está funcionando. Arquivo .conf (deixei os comentários, pois sou novo nisso, eles são úteis):

    # /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
