I have a Raspberry PI B with openSUSE 13.2 (JeOS) which has two USB
interfaces, a Bluetooth and WiFi (Realtek RTL8192cu). It worked OK during
installation at home, but at its destination the WiFi connection does not come
up. I can do "iwlist wlan0 scan" and I get the list of Access Points it the
neighborhood. The device is configured with wicket. For access I use the
Ethernet port (it works headless). I have the same system on another device,
same software, same type of devices, same network configuration and that one
works as expected. I can bring the interface down with "ifdown wlan0" and up
again with "ifup wlan0 -o debug" and the last lines of the output are:
wicked: waiting for 1 devices to become ready (1 explicitly requested)
wicked: wlan0: state=firewall-up want=network-up, wait-for=link-up
wicked: waiting for 1 devices to become ready (1 explicitly requested)
wicked: wlan0: state=firewall-up want=network-up, wait-for=link-up
wicked: waiting for 1 devices to become ready (1 explicitly requested)
wicked: device wlan0 failed: operation timed out
wicked: waiting for 0 devices to become ready (0 explicitly requested)
wicked: finished with all devices.
wicked: wlan0: changed state none -> device-exists, still waiting for event
wlan0 setup-in-progress
wicked: Exit with status: 162
On the device that does work, instead of the timeout I get:
wicked: ... great, we were expecting this event
wicked: wlan0: changed state firewall-up -> link-up, resuming activity
wicked: wlan0: state=link-up want=network-up, trying to transition to link-
authenticated
wicked: wlan0: changed state link-up -> link-authenticated
wicked: wlan0: successfully transitioned from link-up to link-authenticated
wicked: wlan0: state=link-authenticated want=network-up, trying to transition
to lldp-up
wicked: wlan0: calling org.opensuse.Network.LLDP.lldpUp()
wicked: wlan0: changed state link-authenticated -> lldp-up
wicked: wlan0: successfully transitioned from link-authenticated to lldp-up
wicked: wlan0: state=lldp-up want=network-up, trying to transition to network-
up
wicked: wlan0: calling
org.opensuse.Network.Addrconf.ipv4.static.requestLease()
wicked: wlan0: changed state lldp-up -> network-up
wicked: wlan0: cancel timeout
wicked: wlan0: successfully transitioned from lldp-up to network-up
wicked: waiting for 0 devices to become ready (0 explicitly requested)
wicked: finished with all devices.
wicked: wlan0: tentative addresses check
wlan0 up
wicked: Exit with status: 0
I found on the Internet problems with the power drawn via the USB ports. But
it that case the WiFi connection got established, but was unstable. The same
device with the same interfaces and the same power supply worked for almost 9
month without any problem with openSUSE 13.1. Because the SD card broke down I
had to reconfigure the software. I have a similar device doing the same thing,
with the same type of devices and also with openSUSE 13.2 working OK.
Any suggestions?
