They also cannot find 5G wifi networks, only 2G ones. The laptop came with Windows 8.1 64 but I installed Ubuntu 14.04 64 Bit alongside Windows, even though I only boot into my Ubuntu partition now. Also, I have installed both WICD Network Manager AND Ubuntu's Network Manager on my system, but for the purposes of this bug I am only using Ubuntu's Network Manager i.e. I am not opening WICD. I am including this information in case even installing WICD may be causing a conflict. ------------------------- The problem ------------------------- At work I use Ethernet, so when I plug the cable in in the morning my computer connects straight away to the internet through Network Manager! When I come home, I use wifi and expect it to connect straight away but it keeps saying its authenticating and then does not connect. I can see all the 2G wifi networks, but network manager just cannot connect to them straight away. Network manager will keep trying for up to an hour and then suddenly it will connect like magic! ------------------------- What solutions I tried that did not work ------------------------- * Using software updater to update my system fully * Restarting my laptop * Restarting the router * Connecting to the wifi with my phone (works fine!) whilst I am struggling to connect with my laptop * Disabling network manager and re-enabling it * Disabling wifi then re-enabling it * Disabling wifi and networking and then re-enabling it * In Terminal: `sudo service network-manager restart` ------------------------- What I am going to try ------------------------- * Move fully to WICD (which I have done in the past!) OR delete WICD totally and only keep network manager * Check to see if my particular card has any known issues with Ubuntu and try to solve those * I'm open to other suggestions ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.16.0-33-generic 3.16.0-33.44~14.04.1 ProcVersionSignature: Ubuntu 3.16.0-33.44~14.04.1-generic 3.16.7-ckt7 Uname: Linux 3.16.0-33-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.7 Architecture: amd64 CurrentDesktop: Unity Date: Fri Apr 10 20:04:48 2015 EcryptfsInUse: Yes InstallationDate: Installed on 2015-03-23 (17 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) SourcePackage: linux-lts-utopic UpgradeStatus: No upgrade log present (probably fresh install) --- ApportVersion: 2.14.1-0ubuntu3.8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: jas 3233 F.... pulseaudio /dev/snd/controlC0: jas 3233 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 EcryptfsInUse: Yes InstallationDate: Installed on 2015-03-23 (18 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) MachineType: LENOVO 20378 Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-33-generic root=UUID=3bbe0750-5817-4b2c-a1c7-07ab9d8ea1fb ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.16.0-33.44~14.04.1-generic 3.16.7-ckt7 RelatedPackageVersions: linux-restricted-modules-3.16.0-33-generic N/A linux-backports-modules-3.16.0-33-generic N/A linux-firmware 1.127.11 Tags: trusty Uname: Linux 3.16.0-33-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 08/18/2014 dmi.bios.vendor: LENOVO dmi.bios.version: 9ECN31WW(V1.14) dmi.board.asset.tag: 31900058WIN dmi.board.name: Lenovo Y50-70 dmi.board.vendor: LENOVO dmi.board.version: 31900058WIN dmi.chassis.asset.tag: 31900058WIN dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo Y50-70 dmi.modalias: dmi:bvnLENOVO:bvr9ECN31WW(V1.14):bd08/18/2014:svnLENOVO:pn20378:pvrLenovoY50-70:rvnLENOVO:rnLenovoY50-70:rvr31900058WIN:cvnLENOVO:ct10:cvrLenovoY50-70: dmi.product.name: 20378 dmi.product.version: Lenovo Y50-70 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1442781/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
