Hardware & Software

Tenda u1, rtl8192eu chipset.
Could be found as wireless adaptor, but could not get networking.

# sudo wifi-menu wlp37s0u1
# dmesg
[42647.461034] wlp37s0u1: send auth to **:xx:xx:xx:xx:xx (try 1/3)
[42647.663969] wlp37s0u1: send auth to **:xx:xx:xx:xx:xx (try 2/3)

[42648.070657] wlp37s0u1: authentication with xx:xx:xx:xx:xx:xx timed out

Kernel Version:

$ uname -r


Install wireless_tools and use iwconfig for detecting the hardware:

$ sudo pacman -S wireless_tools
$ sudo iwconfig
wlp37s0u1  IEEE 802.11  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry short limit:7   RTS thr=2347 B   Fragment thr:off
          Encryption key:off
          Power Management:off

Seems the driver have some problem, so I got the following url, and run the same procedures as its comments:


Install it via:

$ yaourt 8192eu-dkms

Configure it via:

$ sudo vim /etc/modprobe.d/wlan.conf
blacklist rtl8xxxu
install rtl8xxxu /bin/false

Now reboot machine and examine the rtl8xxxu is not loaded via lsmod | grep -i 8xx, since we use the right device driver, our wireless adapter will work properly and connect to wifi ap.
