Hi. I got lenovo x200 with Intel WiMAX adapter onboard and Kubuntu 9.10. Wifi works perfectly, but wimax doesn't. Even light diode, that shows wimax activity, not blinking at all. I tried to use different drivers(built in and fresh from git repository) without success. Here some information: $ uname -a Linux pr1-ru 2.6.31-16-generic #52-Ubuntu SMP Thu Dec 3 22:00:22 UTC 2009 i686 GNU/Linux What i'm doing: Loading driver ./load.sh: dmesg: [ 655.672989] i2400m_usb 2-3:1.0: WiMAX interface wmx0 (00:1d:e1:0a:55:c5) ready [ 655.673020] i2400m_usb 2-3:1.0: firmware: requesting i2400m-fw-usb-1.4.sbcf [ 657.896539] i2400m_usb 2-3:1.0: firmware interface version 9.2.0 [ 657.904655] usbcore: registered new interface driver i2400m_usb [ 657.906768] ADDRCONF(NETDEV_UP): wmx0: link is not ready /etc/init.d/wimax start # wimaxll-rfkill wmx0 on I: rfkill status is 0x3 (HW on SW on) (off works normally too) # wimaxcu ron HW and SW Radios are ON. # wimaxcu reset factory WiMAX system is set to factory settings. # wimaxcu scan No networks found. # lsmod | grep 2400 i2400m_usb 29888 0 i2400m_sdio 18624 0 i2400m 97164 2 i2400m_usb,i2400m_sdio wimax 27072 1 i2400m logs: system_log: {pid:2386, tid: 3078941552} [1260039289] ./wimax_string.c:58 Error: [memcpy_s]Exit Error source buffer is NULL or format is NULL {pid:2386, tid: 3078941552} [1260039292] ./wimax_string.c:58 Error: [memcpy_s]Exit Error source buffer is NULL or format is NULL {pid:2386, tid: 3078941552} [1260039294] ./wimax_string.c:58 Error: [memcpy_s]Exit Error source buffer is NULL or format is NULL {pid:2386, tid: 3078941552} [1260039294] ./wimax_string.c:58 Error: [memcpy_s]Exit Error source buffer is NULL or format is NULL # wimaxcu info device WiMAX Device Info: Manufacturer: Intel(R) Corporation HW Model : Intel(R) WiMAX/WiFi Link 5150 HW Version : 778 FW Version : WIMAX_SW_EP.4.1.20 MAC Address : 00:1D:E1:0A:55:C5 NVM Img Ver.: 1538 lspci: 03:00.0 Network controller: Intel Corporation WiMAX/WiFi Link 5050 Series # rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: tpacpi_bluetooth_sw: Bluetooth Soft blocked: no Hard blocked: no 3: i2400m-usb:2-3:1.0: WiMAX Soft blocked: no Hard blocked: no Thanks.
