I found a workaround that I introduce here for the case it can help some other people in my situation, as well as for the case it gives a clue for a potential fix:
- I duplicated my local wifi connection and in one of the two I modified the default options to adhoc, B/G 2.4GHz, Channel 1 (I also changed the label to know which one is each) - Then I manually connect the modified wifi connection, but right at the time it is requesting an IP, I rapidly connect the other (default) connection If I do it in this specific order, then the default network works. If I just try to connect either of the two without replicating this sequence, the two fail miserably.

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. Hence, I decided to report this new bug, as the issue may be different to others. --------------------------------------------- Ubuntu 3.16.0-28.37-generic 3.16.7-ckt1 --------------------------------------------- lsb_release -rd Description: Ubuntu 14.10 Release: 14.10 --------------------------------------------- linux-image-3.16.0-28-generic: Instaŀlat: 3.16.0-28.37 Candidat: 3.16.0-28.37 Taula de versió: *** 3.16.0-28.37 0 500 http://mirror.cc.columbia.edu/pub/linux/ubuntu/archive/ utopic-updates/main amd64 Packages 500 http://mirror.cc.columbia.edu/pub/linux/ubuntu/archive/ utopic-security/main amd64 Packages 100 /var/lib/dpkg/status 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
