[Bug 910054] New: updated driver fixes rtl8723be wifi speed issue
http://bugzilla.opensuse.org/show_bug.cgi?id=910054 Bug ID: 910054 Summary: updated driver fixes rtl8723be wifi speed issue Classification: openSUSE Product: openSUSE 13.1 Version: Final Hardware: x86-64 OS: openSUSE 13.2 Status: NEW Severity: Enhancement Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: erbenton@comcast.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Using kernel 3.18.0-1.gfc82a91-default (note that all other kernel versions I tried resulted in same issue) On Lenovo G50 laptops with Realtek wifi (pci 10ec:b723) There is an issue where the max wireless speed in an excellent wireless environment with AC1750ac/n enabled is limited to less than 5 mbits/s There is an available driver set for rtl wifi from: https://github.com/lwfinger/rtlwifi_new that should be looked at for future updates. My experince has been that installing the code there boosted my wifi to 66 mbits/s All tests were run using iperf bewtween two OpenSuse 13.x machines (13.1 wired ethernet and 13.2 wireless). -- You are receiving this mail because: You are on the CC list for the bug.

But Larry must know of any possible fixes included in rtlwifi_new that can be backported via stable kernel later once when it's merged to upstream. Feel free to provide a rtlwifi_new KMP from OBS. But as a policy, we prefer following the upstream, so this won't be put into FACTORY or released products like openSUSE 13.2. -- You are receiving this mail because: You are on the CC list for the bug.
http://bugzilla.opensuse.org/show_bug.cgi?id=910054 --- Comment #2 from Larry Finger <Larry.Finger@lwfinger.net> --- The work flow was as follows: 1. Troy from Realtek sent me a copy of the new drivers for the rtlwifi family. 2. I placed that code in the3 master branch of the rtlwifi_new git repo. 3. Two new branches were created. The code that is needed to support older kernels has been removed from the kernel_version branch. The troy branch is where Troy places any bug fixes that Realtek finds. I then port those fixes into the master and kernel_version branches, as well as the kernel code. Other than cosmetic differences, as far as I know, the code in the 3.18 kernel and the kernel_version and troy branches are thae same. I just reviewed the diff file between the current wireless-testing git repo and the troy branch to see if any errors had been introduced, but I did not see any. I cannot test driver rtl8723be at the moment, but I will do so later today. In the meantime, if you can identify any critical differennces in the code, please let me know. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=910054 --- Comment #4 from Eric Benton <erbenton@comcast.net> --- I just got an update that takes me from using kernel 3.18.0-1.gfc82a91-default to 3.18.0-2.g99a9f76-default. When I rebooted the wifi speed was again slow at about 4.3 mbits/s using iperf. Installing the attached drivers and reboting bumped me back up to over 65 mbits/s modinfo on the rtl8732be.ko for each kernel doesnt show a version so i cant say much in that regard. (a version string of some kind ought to be mandatory for drivers so you can quickly tell what you have via modinfo) I can make my laptop accessible for inspection or test sw if you want. There is nothing too important on it at the moment. Lenovo G50-70 with core-i7 I dont know if this is useful but here is some data. How do i know if I have the latest (or correct?) FW. I remember messing with that early on due to the wireless didnt work AT ALL when i recieved the laptop and intially installed OpenSuse 13.1 (I was wrong in my above posts, i just checked and it was OpenSuse 13.1 not 13.2 according to /etc/os-release) ls /lib/firmware/rtlwifi -l [snippet] -rw-r--r-- 1 root root 30746 Dec 15 13:34 rtl8723befw.bin -rw-r--r-- 1 root root 22996 Dec 15 13:34 rtl8723fw_B.bin -rw-r--r-- 1 root root 11662 Dec 15 13:34 rtl8723fw.bin lspci shows: # lspci -s 2:0.0 -xxx -vvvv 02:00.0 Network controller: Realtek Semiconductor Co., Ltd.

http://bugzilla.opensuse.org/show_bug.cgi?id=910054 --- Comment #5 from Takashi Iwai <tiwai@suse.com> --- Did you update kernel-firmware package as well from OBS Kernel:HEAD repo? This should contain almost the latest firmware from linux-firmware git repo. -- You are receiving this mail because: You are on the CC list for the bug.
http://bugzilla.opensuse.org/show_bug.cgi?id=910054 --- Comment #6 from Eric Benton <erbenton@comcast.net> --- According to Yast this is installed: kernel-firmware 20130714git-2.21.1 Is that the latest version? -- You are receiving this mail because: You are on the CC list for the bug.
http://bugzilla.opensuse.org/show_bug.cgi?id=910054 --- Comment #7 from Takashi Iwai <tiwai@suse.com> --- It's too old. The latest package is kernel-firmware-20141122git-1.1. -- You are receiving this mail because: You are on the CC list for the bug.
http://bugzilla.opensuse.org/show_bug.cgi?id=910054 --- Comment #8 from Eric Benton <erbenton@comcast.net> --- all i can find in the repo at http://download.opensuse.org/repositories/Kernel:/HEAD/standard/, (and it doesnt show up in yast), is kernel-firmware-20141122git-98.1.noarch.rpm Also, i probably ought to go to 3.18.0-4.1.g0510331 ? -- You are receiving this mail because: You are on the CC list for the bug.
http://bugzilla.opensuse.org/show_bug.cgi?id=910054 --- Comment #9 from Takashi Iwai <tiwai@suse.com> --- The release number doesn't matter but check the version number (20141122git). I'm referring to the FACTORY one, which has a different release number. You can update the kernel package, of course, but there hasn't been any changes in SUSE git tree regarding rtlwifi after 3.18 release, AFAIK. -- You are receiving this mail because: You are on the CC list for the bug.
http://bugzilla.opensuse.org/show_bug.cgi?id=910054 --- Comment #10 from Eric Benton <erbenton@comcast.net> --- That seems toto have worked fine. I now have the latest fw and it shows up in yast too - this can be closed -- You are receiving this mail because: You are on the CC list for the bug.
