TP-Link TL WN823N RTL8192EU

Post by sneh3127 » 2020/09/08 18:35:16

Hello,
Any suggestions on installation of RTL8192EU driver for Centos 8. The device is TP-Link TL WN823N RTL8192EU and my kernel version is 4.18.0-193.14.2.el8_2.x86_64.

What is the Vendor/device id pair from lspci -nn | grep -i net or from lsusb.py for that device? In lspci it'll be a pair of numbers like [8086:100e]

Code: Select all

[root@centos8 ~]# grep -i 2357 /lib/modules/$(uname -r)/modules.* | grep -i 0109
/lib/modules/4.18.0-193.14.2.el8_2.x86_64/modules.alias:alias usb:v2357p0109d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
Apparently supported by rtl8xxxu so try modprobing that and see what dmesg says afterwards and if you have any new interfaces listed in the output from `ip a`

Thank you for the feedback.

The output of the code is : -

# grep -i 2357 /lib/modules/$(uname -r)/modules.* | grep -i 0109 /lib/modules/4.18.0-193.14.2.el8_2.x86_64/modules.alias:alias usb:v2357p0109*dc*dp*icFFiscFFipFFin* rtl8xxxu

grep: /lib/modules/4.18.0-193.14.2.el8_2.x86_64/modules.alias:alias: No such file or directory
grep: usb:v2357p0109*dc*dp*icFFiscFFipFFin*: No such file or directory
grep: rtl8xxxu: No such file or directory

The output of grep in the first part produces result but he STDOUT of grep command in the first part and STDIN as piping to another grep produes no result as : - No such file or directory

As per my system

1 - Regarding modprobe

# lsmod | grep -i rtl
rtl8xxxu 126976 0
mac80211 888832 1 rtl8xxxu

2 - The output of ip a

# ip a

7: wlp0s20u6: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
link/ether <Mac_Address> brd ff:ff:ff:ff:ff:ff
The USB Wireless card is detected as wlp0s20u6 and in Wi-Fi GUI also in I can see the visible Wireless Networks

3 - The output of dmesg when the device is connected is

# dmesg

Now the problem is that when I try to connect the Visible Networks in the Wi-Fi GUI. The dialog box appears as

Authentication Required for Wireless Network

After supplying the correct credentials. It tries to connect and then : -

Connection failed : Activation of Network Connection failed

I tried to check the log files and are as below

Also please check this also :

enabled enabled enabled enabled

And
# systemctl status wpa_supplicant.service
Active and running

SSID is android as detected from GUI
Authentication method is WPA2 Personal

Any suggestions and help will be appreciated and will be helpful to me.

Thanking you again.

You flowed the command I issued and the response to that command into one line and tried to execute it as one thing. That's why it didn't work.

Do you have a firewall that would stop it from talking to the access point and receiving responses from it? Either firewalld/iptables on the machine in question or perhaps an external one between you and the AP.

Hi TrevorH,

Note : - I masked and edited the Mac Adress as <Mac_Address> in word file.

# pwd

/lib/modules/4.18.0-193.14.2.el8_2.x86_64


# cat modules.alias | grep usb:v2357p0109*

alias usb:v2357p0105d*dc*dsc*dp*ic*isc*ip*in* mt76x0u
alias usb:v2357p0100d*dc*dsc*dp*ic*isc*ip*in* rtl8192cu
alias usb:v2357p0109d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
alias usb:v2357p0108d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu

Inside the modules.alias file I can find only these lines for rtl8xxxu

alias usb:v0BDApB720d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
alias usb:v2357p0109d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
alias usb:v2001p3319d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
alias usb:v2357p0108d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
alias usb:v0BDAp818Bd*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
alias usb:v0BDAp0724d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
alias usb:v0BDAp1724d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
alias usb:v0BDAp8724d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu

# systemctl stop firewalld
same issue.

By the way when the device is connected to a VirtualBox Machine (Windows) then it authenticates and connects to the AP perfectly fine.

Any suggestions and any logs you want me to post please let me know.

Thanks a lot
