Moshe Caspi, thank you for reporting this and helping make Ubuntu better. As per http://www.gigabyte.com/products/product-page.aspx?pid=1764#bios an update to your computer's buggy and outdated BIOS is available (F5). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
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, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-f5 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** 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/1528534 Title: No wireless connection on computer start Status in linux package in Ubuntu: Incomplete Bug description: I use tp-link wn723n usb dongle. When I start the computer I am not connected automatically to the router but the hardware is recognized. It looks like the problem is that I get a wrong MAC : kernel: [ 32.481663] MAC Address = 00:e0:4c:81:88:02 which looks like a combination of the first part of the serial number of the dongle: 00e04c, the chip: 8188 and and an index number: 02. I have to remove the dongle and insert it in order for the wireless connection to work. Then I get the correct MAC: kernel: [ 449.752527] MAC Address = c4:e9:84:0c:cb:af It looks like the problem starts here: kernel: [ 56.946579] r8188eu 1-2:1.0 wlan1: renamed from wlan0 even though I have: # USB device 0x:0x (r8188eu) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="c4:e9:84:0c:cb:af", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0" # USB device 0x:0x (r8188eu) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:e0:4c:81:88:02", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan1" If I reboot the computer at this point that I have a connection to the router, magically I am automatically connected again to the router. Here are 2 same issues with wrong MACs and the same chip: https://lists.openwrt.org/pipermail/openwrt- devel/2014-November/029401.html https://github.com/lwfinger/rtl8188eu/issues/75 ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: linux-image-3.19.0-41-generic 3.19.0-41.46 ProcVersionSignature: Ubuntu 3.19.0-41.46-generic 3.19.8-ckt10 Uname: Linux 3.19.0-41-generic i686 ApportVersion: 2.17.2-0ubuntu1.8 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: moshe 977 F.... lxpanel CurrentDesktop: LXDE Date: Tue Dec 22 12:25:13 2015 HibernationDevice: RESUME=UUID=5e5eaba6-2f6f-4a5f-8a75-9b6cd6841e46 InstallationDate: Installed on 2015-01-06 (349 days ago) InstallationMedia: Lubuntu 14.10 "Utopic Unicorn" - Release i386 (20141022.1) ProcFB: 0 VESA VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.19.0-41-generic root=UUID=a94f05c3-f057-45de-bc12-2c8c7c502cd4 ro RelatedPackageVersions: linux-restricted-modules-3.19.0-41-generic N/A linux-backports-modules-3.19.0-41-generic N/A linux-firmware 1.143 RfKill: SourcePackage: linux StagingDrivers: r8188eu UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 01/14/2004 dmi.bios.vendor: Award Software International, Inc. dmi.bios.version: F1 dmi.board.name: 7VM400M-RZ dmi.board.vendor: Gigabyte Technology Co., Ltd. dmi.board.version: x.x dmi.chassis.type: 3 dmi.modalias: dmi:bvnAwardSoftwareInternational,Inc.:bvrF1:bd01/14/2004:svn:pn:pvr:rvnGigabyteTechnologyCo.,Ltd.:rn7VM400M-RZ:rvrx.x:cvn:ct3:cvr: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1528534/+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
