Nicolò Chieffo, as per http://www.dell.com/support/drivers/us/en/19/Product/latitude-e6400 an update is available for your BIOS (A34). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?
If not, 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 Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Tags removed: kernel-request-3.2.0-19.30 ** Tags added: bios-outdated-a34 bot-stop-nagging ** Summary changed: - wifi notworking + 8086:4232 [Dell Latitude E6400] wifi notworking ** Summary changed: - 8086:4232 [Dell Latitude E6400] wifi notworking + 8086:4232 [Dell Latitude E6400] wifi not working ** No longer affects: wpasupplicant (Ubuntu) ** Changed in: linux (Ubuntu) Status: Triaged => 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/956519 Title: 8086:4232 [Dell Latitude E6400] wifi not working Status in The Linux Kernel: Confirmed Status in “linux” package in Ubuntu: Incomplete Bug description: The wifi is enabled and connected to the correct access point.
