Long sequences of pings to the access point IP show 25-30% packet loss. Downloads get 'stuck', pages don't load, it's generally unusable. I've tried the following kernels: /boot/initrd.img-3.11.0-12-generic /boot/initrd.img-3.12.3-031203-generic /boot/initrd.img-3.11.0-14-generic /boot/initrd.img-3.13.0-031300rc3-generic all with the same result. Packet capture shows lots of dup ACKs, some retransmits. I suspected 802.11n might be the culprit, but I've disabled it at the AP, and the driver seems to respect that judging by these log lines: Dec 7 21:50:52 congo kernel: [13812.218008] rtl8188ee 0000:01:00.0 wlan0: disabling HT as WMM/QoS is not supported by the AP Dec 7 21:50:52 congo kernel: [13812.218011] rtl8188ee 0000:01:00.0 wlan0: disabling VHT as WMM/QoS is not supported by the AP Other than those lines there isn't anything noteworthy in syslog. Very interested in getting this fixed, please let me know how I can help debug. $ lsb_release -rd Description: Ubuntu 13.10 Release: 13.10 $ uname -a Linux congo 3.13.0-031300rc3-generic #201312061335 SMP Fri Dec 6 18:37:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux $ sudo lshw -C network *-network description: Wireless interface product: RTL8188EE Wireless Network Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:01:00.0 logical name: wlan0 version: 01 serial: 34:23:87:0d:23:85 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtl8188ee driverversion=3.13.0-031300rc3-generic firmware=N/A ip=192.168.1.68 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn resources: irq:18 ioport:5000(size=256) memory:b2600000-b2603fff *-network description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:09:00.0 logical name: eth0 version: 0c serial: 9c:b6:54:c1:7d:36 size: 10Mbit/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=half firmware=rtl8168g-2_0.0.1 02/06/13 latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:43 ioport:3000(size=256) memory:b2500000-b2500fff memory:b2400000-b2403fff To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1258870/+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
