Hi, the network manage showed me: Wired network device not managed Wireless network wireless is disabled I reboot and also tried /etc/initi.d/network-manage restart not work It used to work, but this afternoon I guess I disabled the wireless when chose to use cable, but now stuck how to get it back. do i need re-install the network-manage or which commands I should use. some attempted click on the interface not work. Thanks, Best regards,
