4.3.8 Known issues
Network interface renaming
After installation, CentOS/RHEL 6 sometimes decides to rename network interfaces, e.g. from
“wlan0” to “wlan4” or “rename11”. This prevents proper operation of Soft Eye, as it no longer
recognizes the network interfaces.
Symptoms:
 Tests are not running.
 Following entry can be found from system log:
7signalCore: WLANDriverManager: Failed to set interface mode: Could not resolve
device index of net device
Solution:
 Open file /etc/udev/rules.d/70-persistent-net.rules in editor
 Locate lines:
# PCI device <device ID> (<driver name>)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="<WLAN
MAC address>", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"
# PCI device <device ID> (<driver name>)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="<WLAN
MAC address>", ATTR{type}=="803", KERNEL=="wlan*", NAME="wlan1"
 Verify that on line containing text "ATTR{type}=="1"", the value of the NAME parameter is
“wlan0”
 Verify that on line containing text "ATTR{type}=="803"", the value of the NAME parameter is
“wlan1”
 Remove all other lines referring to WLAN interfaces
