Similar Problem here on my Dell E6500 (Intel Corporation Wireless WiFi Link 5100).
Using the Network Manager I am unable to connect to a wireless network. Using th commandline "iwlist scan" sometimes finds my wireless network and sometimes it does not. But no matter if the network is found I am always unable to connect. dmesg says ADDRCONF(NETDEV_UP): wlan0: link is not ready -- BOTH Network controller: Intel Corporation Wireless WiFi Link 5100 AND Ethernet controller: Marvell Technology Group Ltd. 88E8040T PCI-E Fast Ethernet Controller (rev 12) FAIL TO LOAD! https://bugs.launchpad.net/bugs/407824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
