Wireless Network Driver

Postby kissellj » 2017/11/11 20:25:25

2 Questions on this please.

I'm trying to locate on the Elrepo Site the driver for kmod-r8192cu. I'm trying to get the wireless setup for
lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 046d:0826 Logitech, Inc. HD Webcam C525
***Bus 001 Device 003: ID 0b05:17ab ASUSTek Computer, Inc. USB-N13 802.11n Network Adapter (rev. B1) [Realtek RTL8192CU]
Bus 001 Device 005: ID 046d:c246 Logitech, Inc. Gaming Mouse G300
Bus 001 Device 002: ID 051d:0002 American Power Conversion Uninterruptible Power Supply
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

1) Does this mean driver is installed? If not I searched the mirror sites for the kmod-r8192c and am not finding it.

2) Below is what I get trying to install NetworkManger on command line with Gnome GUI. I don't see a GUI when I type
[root@localhost ~]# yum install NetworkManager
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: mirrors.syringanetworks.net
* elrepo: muug.ca
* extras: denver.gaminghost.co
* updates: mirror.raystedman.net
Package 1:NetworkManager-1.8.0-11.el7_4.x86_64 already installed and latest version

When I try to run [root@localhost jkissell]# NetworkManager I dont see a GUI. What command brings the GUI up in GNOME? Once I get the card working I will need some help with configuration.

The rtl8192cu module is already part of the CentOS 7.4 kernel. What is the output from uname -a ?

You already have the driver.

What command is needed to get the MAC address for the usb wireless card (see red below)? Does it need to be in single quotes?

I created 2 files in /etc/sysconfig/network-scripts. They are
keys-myqwest4XXX
ifcfg-myqwest4XXX

Content of keys-myqwest4XXX
WPA-PSK='11bxxe4400b6xxx3axxxxbd536'
Is the syntax correct for the script? My WPA key in single quotation marks?

Content of ifcfg-myqwest4XXX
ESSID="myqwest4XXX"
MODE=Managed
KEY_MGMT=WPA-PSK
TYPE=Wireless
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=<ESSID>
UUID=<THE_UUID>
ONBOOT=yes
HWADDR=<THE_MAC_ADDRESS>
BSSID=<BSSID>
PEERDNS=yes
PEERROUTES=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
