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

    1) installed fresh leap 15
    2) install_bcm43xx_firmware
    3) installed all suse updates
    4) still slow
    5) added pacman repository in yast and checked that contains correct leap 15 url of pacman
    6) tried to install

    zypper in -f broadcom-wl broadcom-wl-kmp-default


    7) intall broken/failed and even wlan/wire visible no Network connection now not at all.

    Maybe somebody else with D620 with Core2Duo with BCM4311 will continue this issue solving

    Thanks from support to all.

    Post the error of:
    Code:
    zypper in -f broadcom-wl broadcom-wl-kmp-default
    Also
    Code:
    cat /var/log/zypp/history

    Installing new is also not the best choice............

    Also the answer of post #10 is missing.........

    After some break this done when looks that driver problem as it worked in Suse Leap 42.3:
    1) Install Suse Leap 15 with Gnome desktop
    then connect with wire to network
    2) Run all updates from Yast (additional: if you have extra hardisk clone spare backup to make easy to start again possible)
    3) open YAST -> open software management and remove package b43-fwcutter (allow
    also removal of pullin-pcm43xx-firmaware when b43-fwcutter removed
    4) Open web browser and open software warehouse: https://software.opensuse.org/
    and use its search too find b43-fwcutter (show all versions) and select openSUSE Leap 42.3 version of b43-fwcutter and start 1-click istallation on web page.
    5) After installation b43-fwcutter of openSUSE Leap 42.3 is in use.
    6) Restart computer
    7) Run install_bcm43xx_firmware in terminal
    >sudo /usr/sbin/install_bcm43xx_firmware
    8) restart computer; now wlan icon is visible but connection to network fails.
    9) pullin-pcm43xx-firmaware of openSUSE Leap 42.3 must be removed ( use YAST )
    10) open software warehouse (https://software.opensuse.org/) and search pullin-pcm43xx-firmaware and install openSUSE 15 pullin-pcm43xx-firmaware version with start 1-click istallation.
    11) Run install_bcm43xx_firmware in terminal
    >sudo /usr/sbin/install_bcm43xx_firmware
    12) Restart computer
    13) After restart check from terminal
    >dmesg|grep -i b43
    ..on output should be line with "Loading firmware version 666.2"
    14) Now wlan icon is visible and connection also happens and browsing of web
    works as it should (fast)

    It looks that new latest b43 (784.2 ?) firmware of Suse 15 fails but older of Suse leap 42.3 (666.2) works.

    Thank to all that earlier helped in this question.

    As suspected (post #6), a firmware issue. A bug report should probably be submitted for this.
    openSUSE Leap 15.4; KDE Plasma 5

    Noticed after running last Suse 15 Leap online updates that those updates brake wlan connection and unfortunately also wired connection is broken ( shows ? -symbol in both cases) when istallation has fix of message #13 (firmware version 666.2 of Leap 42.3 used). Using components from different versions used to fail.

    If fix of message #13 is used to get wlan working it's recommended to clone hardisk (as backup of working wifi installation ) before running Leap 15 updates.
