Thread: Wlan with Broadcom wlan circuit (BCM4311 802.11a/b/g) too slow problem

  1. #1

    Default Wlan with Broadcom wlan circuit (BCM4311 802.11a/b/g) too slow problem

    Installed Suse Leap 15 with Gnome on Dell D620 with sticker "Intel Core 2 Duo" with Intel Core2 T5600 (Dual core 1,83GHz) with Broadcom wlan circuit (BCM4311 802.11a/b/g) and after installation wlan was missing, but driving install_bcm43xx_firmware wlan was present (with b43), but in this case wlan is unusable because of slow speed 1-11Mb/s (earlier with Suse 42.3 version with same Broadcom wlan was working proper speeds). How to fix speed problem ?

    Assuming wlan0 is the applicable wireless device node, please show the output of
    Code:
    iw dev wlan0 link
    Code:
    iw dev wlan0 info
    Also for general device capabilities....
    Code:
    iw list

    Here information:

    Leap 15

    >iw dev wlan0 link

    freq: 2437
    signal: -42 dBm
    tx bitrate: 9.0 MBit/s
    bss flags: short-preamble short-slot-time
    dtim period: 1
    beacon int: 100

    >iw dev wlan0 info

    ifindex 3
    wdev 0x1
    type managed
    wiphy 0
    channel 6 (2437 Mhz), width 20 MHz (no HT), ceneter1: 2437 MHz
    txpower 20.00 dBm

    and with Leap 42.3 with working wlan has same values except tx bitrate: 48 MB/s ( tested shortly with swapping old hd in)

    I do not know if system is allready mixed bad way with earlier settings tests as wl driver is default (active) when started, but using

    >modbrobe b43
    >rmmod wl

    get wlan on but in unusable slow mode.

    Agreed that is a much lower bitrate than expected. I wonder why (no HT) is reported. Can you please also post the output from
    Code:
    iw list

    If the broadcom-wl package is installed, this then blacklists the b43 driver (via a blacklist file in /etc/modprobe.d/).

    Maybe easier now just to reinstal Leap 15 and try then from clean setup.

    That’s unlikely to help. Perhaps there is some issue with the firmware. More investigation needed.

    Please post the hardware details
    Code:
    /usr/sbin/hwinfo —wlan

    Default Re: Wlan with Broadcom wlan circuit (BCM4311 802.11a/b/g) too slow problem

    Suse Leap 15 reinstalled then:

    1) no wlan available on dektop after installation
    2) checked if b43-fwcutter installed -> Ok ( needed before running install_bcm43xx_firmware)
    >zypper se b43-fwcutter
    3) joined to network with wire and then driven "install_bcm43xx_firmware" -> Ok
    > install_bcm43xx_firmware
    4) wired networking cutted off and no wlan available: next step try reboot to get wlan activated.
    5) reboot done and now wlan network selection possible.
    6) tested connection speed when firefox-browser opens page.-> again unusable slow speed 11Mb/s
    7) tested hwinfo
    >hwinfo --wlan

    Default AW: Wlan with Broadcom wlan circuit (BCM4311 802.11a/b/g) too slow problem

    Yes.

    1. Update your System to get the latest Kernel.
    2. Restart your System.
    3. Add the Packman Repo (you need wired Lan). https://forums.opensuse.org/showthre...SUSE-Leap-42-3
    You have to change the URL of the Repos from 42.3 to 15.0
    http://packman.inode.at/suse/openSUSE_Leap_15.0/
    http://opensuse-guide.org/repo/openSUSE_Leap_15.0/

    Install all multimedia codecs as shown in the thread, switch your installed packages to Packman as shown also in the threat.

    4. Now install broadcom-wl:
    Code:
    zypper in -f broadcom-wl broadcom-wl-kmp-default
    5. Restart your sytem.

    Next step done

    1) Latest Leap 15 updates installed
    2) Wlan still slow
    3) Trying install from http://packman.inode.at/suse/openSUSE_Leap_15.0/
    next packages

    broadcom-wl-6.30.223.271-lp150.10.33.x86_64.rpm
    broadcom-wl-kmp-default-6.30.223.271_k4.12.14_lp150.12.4-lp150.10.33.x86_64.rpm

    done..but with warnings integrity. (click link from browser way to install in yast)

    4) restarted and no wlan present
    5) wlan started running install_bcm43xx_firmware
    6) wlan still unusable slow.

    You should add the Packman Repo as described in the Link.
    broadcom-wl does not need any Firmware!!!!!

    Code:
    zypper se -si broadcom
