Jasdeep Khalsa, as per http://support.lenovo.com/us/en/products/laptops- and-netbooks/lenovo-y-series-laptops/y50-70-notebook-lenovo an update to your computer's buggy and outdated BIOS is available (2.01). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Description changed: - ------------------------- - Summary of my particular setup - ------------------------- - I am using a Lenovo Y50 Laptop which includes the following network cards/adaptors (which I checked with `sudo lshw -class network`): + When I attempt to use wifi it keeps saying its authenticating and then + does not connect. I can see all the 2G wifi networks. Network manager + will keep trying for up to an hour and then suddenly it will connect + like magic! Also, I have installed both WICD Network Manager and + Ubuntu's Network Manager on my system, but I am only using Ubuntu's + Network Manager. - *-network - description: Wireless interface - product: QCA9565 / AR9565 Wireless Network Adapter - vendor: Qualcomm Atheros - physical id: 0 - bus info: pci@0000:08:00.0 - logical name: wlan0 - version: 01 - serial: ac:b5:7d:71:1c:b9 - width: 64 bits - clock: 33MHz - capabilities: pm msi pciexpress bus_master cap_list rom ethernet physical wireless - configuration: broadcast=yes driver=ath9k driverversion=3.16.0-33-generic firmware=N/A ip=192.168.0.6 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn - resources: irq:17 memory:d1600000-d167ffff memory:d1680000-d168ffff - - *-network - description: Ethernet interface - product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller - vendor: Realtek Semiconductor Co., Ltd. - physical id: 0 - bus info: pci@0000:09:00.0 - logical name: eth0 - version: 10 - serial: f0:76:1c:1f:4b:de - size: 10Mbit/s - capacity: 1Gbit/s - width: 64 bits - clock: 33MHz - capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation - configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half firmware=rtl8168g-3_0.0.1 04/23/13 latency=0 link=no multicast=yes port=MII speed=10Mbit/s - resources: irq:46 ioport:3000(size=256) memory:d1504000-d1504fff memory:d1500000-d1503fff - - - I have read reviews that these adapters are not very good - i.e. they - are a bit old. 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 - ------------------------- + I've tried: * 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` + * 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 + 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 + 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 ** Attachment removed: "Dependencies.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1442781/+attachment/4371913/+files/Dependencies.txt ** Attachment removed: "ProcEnviron.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1442781/+attachment/4371914/+files/ProcEnviron.txt ** Tags added: bios-outdated-2.01 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1442781 Title: wifi continually tries to authenticate but fails on Ubuntu 14.04 LTS with network manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1442781/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
