Using 802.11n the internet connection constantly getting lost after a random duration (usually after 20-30 minutes). The NetworkManager applet does not recognize it (still looks like i have a connection), but when I try do disconnect and connect again, there is only one useful information I can find in dmesg: "wlan0: deauthenticating from [ap mac address] by local choice (Reason: 3=DEAUTH_LEAVING)" Reinserting the driver (modprobe -r rtl8723be and modprobe rtl8723) used to be my only workaround, but it does not work anymore and now I have to reboot. Router Manufacturer: EDIMAX Model: BR-6214K Firmware version: 1.40 2008/11/03 08:33:04 Switching to 802.11g (54Mb/s) shows a small performance improvement while browsing websites. However there are still random "ping jumps" and the connection still drops (maybe 1-2 minutes later than usual at least). The following improves performance, but I am still encountering some minor performance issues while playing online games (random lag spikes): sudo nano /etc/modprobe.d/rtl8723be.conf options rtl8723be ips=0 fwlps=0 --- ApportVersion: 2.14.1-0ubuntu3.11 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: pk 1907 F.... pulseaudio /dev/snd/controlC0: pk 1907 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=4ce160f4-029c-4fd5-ba3f-254c6e3e33dd InstallationDate: Installed on 2015-05-24 (0 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) MachineType: LENOVO 20278 Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-38-generic root=UUID=a9da170f-b86b-434f-910b-00929ceb8420 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.16.0-38.52~14.04.1-generic 3.16.7-ckt10 RelatedPackageVersions: linux-restricted-modules-3.16.0-38-generic N/A linux-backports-modules-3.16.0-38-generic N/A linux-firmware 1.127.12 Tags: trusty Uname: Linux 3.16.0-38-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 03/03/2014 dmi.bios.vendor: LENOVO dmi.bios.version: J7ET61WW (2.06 ) dmi.board.asset.tag: Not Available dmi.board.name: 20278 QB0 dmi.board.vendor: LENOVO dmi.board.version: Not Defined dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrJ7ET61WW(2.06):bd03/03/2014:svnLENOVO:pn20278:pvrB5400:rvnLENOVO:rn20278QB0:rvrNotDefined:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20278 dmi.product.version: B5400 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1451233/+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
