I got the same problem om my Dell D520 with Intel Pro 3945. Without warning my wireless connection drops.
dmesg | grep eth1 [17179618.060000] ADDRCONF(NETDEV_UP): eth1: link is not ready [17179859.528000] ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready [17179870.268000] eth1: no IPv6 routers present While the connection is down I can do a "sudo iwlist eth1 scan", and get the SSIDs. But I can't connect to ant of them. I've tried different WLANs, with and without WEP. -- [ Wifi card Intel Pro 3945 ] - My wifi connection "disappears" after a while... https://launchpad.net/bugs/70719 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
