Package: network-manager Version: 0.7.1-1 Severity: normal For a while now I've been having a problem where my wifi connection (on my desktop machine) ends up "non functional". I do not know how to reproduce it and happens maybe about once a week, tho it's far from "regular" (e.g. it happened twice yesterday). I also do not know for a fact that it is caused by network-manager, but I think there's a good chance it's responsible.
Here's my machine setup: - two ethernet interfaces, unconnected, named eth-up and eth-down. - one wifi interface (USB dongle) configured with wpa-roam, named wlan0, which connects to my home router to access my DSL line. - one pseudo "ethernet USB dongle" (really, a neo Freerunner phone using the g_ether module on the other end), named usb0. - two PPTP VPN connections (ppp0 and ppp1). - I also had a wlan0:0 alias (with static IP 192.168.168.169), which I just stopped using yesterday. They're all configured in /etc/network/interfaces (appended at the end of this email) usb0 is configured statically to 192.168.0.200. The problem comes when at some point the routing gets all messed up, and the default route ends up pointing to usb0 rather than to wlan0. It seems that when this happens, it also happens that usb0 somehow was handed the 192.168.168.169 IP. I believe the chunk of daemon.log below is relevant: Apr 29 17:46:42 localhost nm-system-settings: SCPlugin-Ifupdown: devices added (udi: /org/freedesktop/Hal/devices/net_fa_fe_cd_0d_96_c3, iface: usb0) Apr 29 17:46:42 localhost nm-system-settings: Ifupdown: get unmanaged devices count: 4 Apr 29 17:46:42 localhost NetworkManager: <info> (usb0): new Ethernet device (driver: 'cdc_ether') Apr 29 17:46:42 localhost NetworkManager: <info> (usb0): exported as /org/freedesktop/Hal/devices/net_fa_fe_cd_0d_96_c3 Apr 29 17:46:42 localhost avahi-daemon[3501]: Joining mDNS multicast group on interface usb0.IPv4 with address 192.168.0.200.
