avlas, could you please provide your home router manufacturer, model, and firmware version?
As well, while the scope of this report will center around your home router, regarding your university router, do either or both of the following provide a WORKAROUND: 1) Adjust the line in /etc/modprobe.d/iwlwifi.conf to: options iwlwifi 11n_disable=1 and then restart. 2) (This also applies to your home router): If power management is off, execute at a terminal: sudo iwconfig wlan0 power off ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1403142 Title: [Lenovo Thinkpad X1 Carbon 2nd Gen 20A7,20A8] iwlwifi intel 7260 network does not connect Status in linux package in Ubuntu: Incomplete Bug description: Connection to the home and university wireless fail to connect. In the terminal I see repeated messages "no association and the time is already over". In contrast I can work and send this bug report through the hot spot wireless of my cellphone with no problem. I checked many bugs on the internet and tried many different things, none of those succeeded. For instance, I tried kernel from the proposed repository, I tried with multiple options of the iwlwifi module, I tried installing new versions of the firmware. 03:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b2] (rev 83) Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:c270] ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: linux-image-3.16.0-28-generic 3.16.0-28.37 ProcVersionSignature: Ubuntu 3.16.0-28.37-generic 3.16.7-ckt1 Uname: Linux 3.16.0-28-generic x86_64 ApportVersion: 2.14.7-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: jsardid 2608 F.... pulseaudio /dev/snd/controlC0: jsardid 2608 F.... pulseaudio CurrentDesktop: KDE Date: Tue Dec 16 11:49:01 2014 EcryptfsInUse: Yes InstallationDate: Installed on 2014-12-12 (4 days ago) InstallationMedia: Kubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) MachineType: LENOVO 20A8S30G00 ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-28-generic.efi.signed root=UUID=15cbe5cb-55eb-4579-8e23-dd0b1aa46557 ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-3.16.0-28-generic N/A linux-backports-modules-3.16.0-28-generic N/A linux-firmware 1.138 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 11/20/2014 dmi.bios.vendor: LENOVO dmi.bios.version: GRET42WW (1.19 ) dmi.board.asset.tag: Not Available dmi.board.name: 20A8S30G00 dmi.board.vendor: LENOVO dmi.board.version: SDK0E50510 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrGRET42WW(1.19):bd11/20/2014:svnLENOVO:pn20A8S30G00:pvrThinkPadX1Carbon2nd:rvnLENOVO:rn20A8S30G00:rvrSDK0E50510WIN:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20A8S30G00 dmi.product.version: ThinkPad X1 Carbon 2nd dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1403142/+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
