• USB Adapter TP-Link don't show Wi-Fi networks


    Hi guys,
    I purchased this adapter TL-WN723N a few days ago but I’m not able to connect any Wi-Fi network.

    Aparently is working but it doesn’t show Wi-Fi list:

    By the way, I’ve already installed 8188eu-dkms driver from aur:

    [[email protected] ~]$ lsusb
    Bus 001 Device 005: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
    
    
    [[email protected] ~]$ uname -r
    4.9.6-1-ARCH
    
    

    As you can see it appears as down:

    [[email protected] ~]$ ip link list dev enp0s20f0u11
    4: enp0s20f0u11: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000
    
    

    And it doesn’t show any Wi-Fi:

    [[email protected] ~]$ sudo iwlist enp0s20f0u11 scan
    enp0s20f0u11  No scan results
    
    

    Currently I’m using usb tethering from my android device :weary: .

    Could you help me please?

  • ip link set enp0s20f0u11 up
    
    dmesg | grep firmware
    

    will show you if the firmware is loaded…

    @joekamprad What does it mean?

  • this is for GPU not your Wifi…
    Is your module loaded?

    sudo modprobe 8188eu

  • @joekamprad it shows empty

  • lsmod | grep 8188eu
    

    needs to show some like that:

    % lsmod | grep 8188eu                     :(
    r8188eu               409600  0

  • But i think you do not need 8188eu-dkms try uninstalling and reboot…
