Thread: Leap 42.1 on HP ProBook 4535s, Wireless (Atheros AR9285) not working

    Default Leap 42.1 on HP ProBook 4535s, Wireless (Atheros AR9285) not working

    I'm trying to save my fathers Laptop (made unusable by Windows 10's enforced 'optional' upgrade ) with the latest Open Suse.

    While almost everything works out of the box, I'm a bit surprised that wireless with Atheros AR9285 (which I don't remember as a problematic chip on linux) doesn't seem to work.

    Code:
    linux-xn60:~ # hwinfo --wlan

    Hi
    Just check it's not blocked, from the install medium (or via ethernet) install rfkill;
    Code:
    rfkill list
    Also check the hp-wmi modules are installed, does the backlight work Fn keys work etc?

    I've had HP ProBook 4430s and 4440s systems which used the ath9k modules without problems.

    Well, certainly not the driver as I have the exact same card working without
    problems here.

    A first (wild) guess, some rfkill switch activated?

    /usr/sbin/rfkill list

    This is what rfkill says:

    Sorry for double-posting, I couldn't edit the old post anymore: although the the FN keys (backlight, volume etc.) work, the wireless button doesn't. Tried to load the module, which happened, but without any effect.

    Code:
    linux-xn60:~ # modprobe hp-wmi
    linux-xn60:~ # lsmod|grep wmi
    hp_wmi                 16384  0 
    sparse_keymap          16384  1 hp_wmi
    rfkill                 28672  6 cfg80211,hp_wmi,bluetooth
    wmi                    20480  1 hp_wmi

    Disclaimer:

    This is just a wild guess.

    As root run:

    modprobe -rv ath9k

    modprobe -v ath9k nohwcrypt

    Now have a look at rfkill output again and try to unblock it via wireless key if
    necessary and see if that works now.

    If there is no change, have a look at the UEFI/BIOS settings if there is some
    option like "Wireless always on" or similar.

    In a nutshell, your wireless card is hardware blocked, normally rfkill can not
    unblock this as it is a tool for soft(ware) blocking a device.

    There are also cases, where some (undocumented, non-standard) way of blocking
    the device in Windows (or when shutting down Windows) is deactivating wireless
    in a way linux can not unblock it.

    If so, you're screwed unless you have some Windows installed and running to get
    rid of this.

    Hi, never had a ProBook 4535 but other HP/Compaqs showed a similar status when Windows was shutdown with WiFi switched off and the only remedy was firing up Win, making sure WiFi was switched on (often via a custom "HP Wireless Assistant") and then reboot.
    Hope This Helps.

    ****, make that

    modprobe -rv ath9k

    modprobe -v ath9k nohwcrypt=1

    Sorry for the late reply (it's been a busy week for me), I thank you for all the answers/tips.

    I've tried everything to get it working, but the onboard wifi interface stays blocked. I even installed an old copy of Win 7 (without activating and internet), to see if Windows manages to solve the problem (which wasn't the case, not even with HP's drivers). And the BIOS didn't help either. All I managed to do there was 'disabling' wifi and bluetooth, which, strange enough, was still recognized under Linux and the corresponding modules were loaded.

    What I did now was simply buying an Edimax USB-Wifi-Stick, which works like a charm, but I needed to blacklist the ath9k module, because Network-Manager kept using the blocked Atheros-Wifi.

    Considering how well this aged laptop is doing with Open Suse Leap 42.1, it's alarming how Windows 10 could practically 'destroy' the machine. It was slow, it couldn't be put on standby/sleep, it often freezed, aged software and drivers were removed without any replacement available, and obviously, it even killed the wifi.

    This may (or may not) be relevant.

    One use found the following steps revived the wireless card. YMMV.

    - Shut down laptop
    - Remove power cable & battery
    - Press power switch for 30 sec
    - Attach power
    - Power up laptop without battery
    - Switch on wifi ---it works
    - Now switch on the laptop with battery
