I updated my BIOS, and tested this with the Ubuntu 14.10 live CD. It seems much improved. I got 23 Mb/s in Linux vs 33 Mb/s in Windows on speedtest.net. Obviously that is not the ideal way to test, but my router doesn't have a speed test mechanism, and both tests were performed within a couple of minutes of each other.
So it seems it still isn't quite as good as on Windows, but it is far far better than the ~50 kB/s I was getting previously so I'd say this can be closed. ** Changed in: linux (Ubuntu) Status: Expired => Fix Released -- 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/1208197 Title: 7392:7811 Edimax EW-7811UN wifi speeds lower than in Windows Status in “linux” package in Ubuntu: Fix Released Bug description: I have an EW-7811UN wifi dongle. It does work (connects to networks). However it is much slower than in Windows (2Mb/s vs at least 15 Mb/s). Absolutely nothing changed between tests except I rebooted into Windows. Same USB port, same time, same position, etc. This is with Ubuntu 13.04 --- ApportVersion: 2.9.2-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: thutt 1853 F.... pulseaudio /dev/snd/controlC0: thutt 1853 F.... pulseaudio DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=a34186c7-adad-45aa-a1bb-50ad393c192b InstallationDate: Installed on 2012-12-23 (223 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) MachineType: System manufacturer System Product Name MarkForUpload: True NonfreeKernelModules: nvidia Package: linux (not installed) ProcFB: ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.8.0-27-generic root=UUID=7a24a1be-e5e6-41bd-adf7-2f7ec818c97d ro quiet splash ProcVersionSignature: Ubuntu 3.8.0-27.40-generic 3.8.13.4 RelatedPackageVersions: linux-restricted-modules-3.8.0-27-generic N/A linux-backports-modules-3.8.0-27-generic N/A linux-firmware 1.106 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Tags: raring Uname: Linux 3.8.0-27-generic x86_64 UpgradeStatus: Upgraded to raring on 2013-05-12 (83 days ago) UserGroups: adm cdrom dialout dip lp lpadmin plugdev sambashare sudo dmi.bios.date: 05/10/2011 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 0701 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: P8H67-M dmi.board.vendor: ASUSTeK Computer INC. dmi.board.version: Rev 1.xx dmi.chassis.asset.tag: Asset-1234567890 dmi.chassis.type: 3 dmi.chassis.vendor: Chassis Manufacture dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr0701:bd05/10/2011:svnSystemmanufacturer:pnSystemProductName:pvrSystemVersion:rvnASUSTeKComputerINC.:rnP8H67-M:rvrRev1.xx:cvnChassisManufacture:ct3:cvrChassisVersion: dmi.product.name: System Product Name dmi.product.version: System Version dmi.sys.vendor: System manufacturer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1208197/+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
