Toshiba NB500, with rtl8188ce wireless card. Lubuntu 14.04 32 bit up-to-date. Tested with 3.13.0.32, 3.13.0.36 & 3.13.0.37.
The wifi is unstable. The connection is lost after about 30 minutes. Reboot is needed for reconnecting. Tried different solutions: http://askubuntu.com/questions/456453/realtek-rtl8188ce-wireless-driver- unstable-in-ubuntu-14-04 http://askubuntu.com/questions/414974/realtek-rtl8192ce-wireless-slow- intermittent-access http://askubuntu.com/questions/503763/connection-dropouts-with-realtek- rtl8188ce https://github.com/FreedomBen/rtl8188ce-linux-driver The best solution (for me) seems to be: echo "options rtl8192ce ips=0 fwlps=0 swlps=0 swenc=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf sudo reboot I'm testing now. It seems to increment stability but after 1 or 2 hours, no connection. I'm using iwevent on a terminal to control how much time it takes to fail. The command: modinfo rtl8192ce provides some information about the options for the module rtl8192ce (used for the rtl8188ce card). And: systool -v -m rtl8192ce permits to see the state of these options. For systool, package sysfsutils is needed. I have more than 100 netbooks with this problem. They used 10.04 and 12.04 before, without this problem! -- 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/1268833 Title: 10ec:8178 Wireless not working in 13.10 and 14.04 for rtl8192ce (RTL8188CE)/asus pce-n15 Status in “linux” package in Ubuntu: Triaged Bug description: in ubuntu / kubuntu 13.10/14.04 with kernel version lower than 3.12 network manager asks the wifi password again and again. using the kernel 3.13rc7 or higher connection is successful, but no access to internet or the router, the ping command is not responding. obed@Kubuntu:~$ sudo lshw -C net [sudo] password for obed: *-network description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:07:00.0 logical name: eth0 version: 06 serial: 8c:89:a5:2a:27:e2 size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl8168e-3_0.0.4 03/27/12 ip=192.168.1.65 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s resources: irq:51 ioport:d000(size=256) memory:d0004000-d0004fff memory:d0000000-d0003fff *-network description: Wireless interface product: RTL8188CE 802.11b/g/n WiFi Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:08:00.0 logical name: wlan0 version: 01 serial: f4:6d:04:a2:9f:dd width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtl8192ce driverversion=3.12.0-031200-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:19 ioport:c000(size=256) memory:fb300000-fb303fff obed@Kubuntu:~$ --- ApportVersion: 2.12.5-0ubuntu2.2 Architecture: amd64 DistroRelease: Ubuntu 13.10 InstallationDate: Installed on 2014-01-10 (3 days ago) InstallationMedia: Kubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MarkForUpload: True Package: linux (not installed) Tags: saucy Uname: Linux 3.13.0-999-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin netdev plugdev sambashare sudo --- ApportVersion: 2.12.5-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: kubuntu 4941 F.... pulseaudio /dev/snd/controlC2: kubuntu 4941 F.... pulseaudio /dev/snd/controlC1: kubuntu 4941 F.... pulseaudio CasperVersion: 1.336ubuntu1 DistroRelease: Ubuntu 13.10 LiveMediaBuild: Kubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: MSI MS-7681 MarkForUpload: True Package: linux (not installed) ProcFB: 0 radeondrmfb ProcKernelCmdLine: noprompt cdrom-detect/try-usb=true file=/cdrom/preseed/username.seed boot=casper maybe-ubiquity initrd=/casper/initrd.lz quiet splash -- maybe-ubiquity ProcVersionSignature: Ubuntu 3.11.0-12.19-generic 3.11.3 RelatedPackageVersions: linux-restricted-modules-3.11.0-12-generic N/A linux-backports-modules-3.11.0-12-generic N/A linux-firmware 1.116 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Tags: saucy Uname: Linux 3.11.0-12-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo dmi.bios.date: 05/31/2011 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: V22.2 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: Z68A-GD65 (MS-7681) dmi.board.vendor: MSI dmi.board.version: 4.0 dmi.chassis.asset.tag: To Be Filled By O.E.M. dmi.chassis.type: 3 dmi.chassis.vendor: MSI dmi.chassis.version: 4.0 dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrV22.2:bd05/31/2011:svnMSI:pnMS-7681:pvr4.0:rvnMSI:rnZ68A-GD65(MS-7681):rvr4.0:cvnMSI:ct3:cvr4.0: dmi.product.name: MS-7681 dmi.product.version: 4.0 dmi.sys.vendor: MSI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1268833/+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
