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?
I'm afraid I don't know what the problem is, but if you have a working setup, you could copy that to the non-working one. Something like: To copy working SD card image. dd bs=4M if=/dev/path/to/sdcard of=workingImage.raw To copy new image to second SD card. dd bs=4M if=workingImage.raw of=/dev/path/to/sdcard Of course, when working with dd, double check your paths. -A -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
