Hi,
I have been struggling to configure usb wifi on Centos 7.
The problem is that It keeps on sending DHCPDISCOVER but do not receive a reply. Which brings me to the conclusion that either #1 the request is not reaching the DHCP Server (my wifi router) [maybe because of the wireless range] or #2 the settings is incorrect and it is actually not hitting the DHCP server. I would exclude #1 as wifi coverage is pretty good at my home and none of my other devices have any issue.
This brings me to #2, for which I seek guidance and your expert opinion.
- USB detected - CHECK
[root@Centos7]# lsusb | grep -i real
Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
- Module loaded - CHECK
[root@Centos7]# lsmod | grep -i 8188
8188eu 830341 0
- ifconfig output
[root@Centos7]# ifconfig wlan0
wlan0: flags=4099<UP, BROADCAST, MULTICAST> mtu 1500
inet6 fe80::e60a:flca:40c5:ffc2 prefixlen 64 scopeid 0x20<link>

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
I configured my network using NetworkManager GNOME GUI as well creating required files in /etc/sysconfig/network-scripts
Following files were created
/etc/sysconfig/network-scripts/ifcfg-wlan0
with ESSID=<my SSID>, KEY_MGMT=WPA-PSK, BOOTPROTO=dhcp, ONBOOT=yes, NAME=<my SSID>, BSSID=<my BSSID>, DEVICE=wlan0
/etc/sysconfig/networks-scripts/keys-<SSID>
WPA_PSK='MY WPA_PSK'
All I see in /var/log/messages is that DHCPDISCOVER messages are sent via wlan0 but no offer is being received.
Any suggestion/idea.
Thanks,

Re: USB wifi network activation
So does anyone know if there is some package with which I can see wifi networks in range.
Re: USB wifi network activation
I think I found the reason:
Sep 21 21:32:07 Centos7 NetworkManager[597]: <info> [1506043927.6059] device (wlan0): driver 'rtl8188eu' does not support carrier detection
Now back to square one - find appropriate driver

Hiya,
I had the same issues on arch linux.
my solution:
wpa_supplicant -B -i wlan0 -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf
lancs
