TP Link T2U Plus Not connecting nor showing any networks (24.04)

  • 772

I run Ubuntu 24.04, I switched from Windows because i got pissed off at a multi billion dollar company that cannot make a proper update. Anyways, I have a TP Link, I tried every driver I could find on GitHub, but nothing worked, I reset the NetworkManager multiple times after every driver install. Still nothing. I found people with the same problem fixed it with one driver which I downloaded and I still have the same issue. The system recognizes the adapter but it doesn't seem to communicate with the router? If anyone could help I would be thankful. Kernel version is 6.8.0.

    Thanks for the help, I figured the .conf was bad in the driver, I changed some values and now it's working. .conf file (I left the comments since I am new to this, they are helpful):

    # /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.
