Thread: No wireless after resume from suspend

    Default No wireless after resume from suspend

    Hi all, I just recently installed openSUSE 12.3 (Gnome as DM) on my laptop and I am facing a problem when I close (or chose suspend from menu) and open lid.

    My network doesn't show wifi networks in range and I can't do anything.

    I've tried to restart network by issuing "systemctl restart network.service" which didn't show me any output. The only thing in /var/log/messages

    systemd[1]: Stopping Network Manager...
    systemd[1]: Starting Network Manager...
    kernel: [ 2575.564263] r8169 0000:04:00.0 eth0: link down
    kernel: [ 2575.564460] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
    kernel: [ 2575.581732] IPv6: ADDRCONF(NETDEV_UP): ath0: link is not ready

    kernel: [ 2575.590627] IPv6: ADDRCONF(NETDEV_UP): ath0: link is not ready
    systemd[1]: Started Network Manager.

    I've tried to search on this forum and on google, so far I couldn't find anything. Any help?

    If you need more info I will drop it here as well. I am running GNU/Linux on this laptop for more than 4 years with no problem like that (and it' still working on other distro I have on other partition) but I am in a search for distro that I will stay with.

    BR,

    Default Re: No wireless after resume from suspend

    If you are using Network manager instead of ifup then you may need to run after network service. Then again i might be wrong
    Code:
    systemctl  restart NetworkManager.service
    GNOME Version 3.20.2
    openSUSE Leap 42.3 64-bit

    Nope, that didn't do anything for real (no output as well).

    Thumbs up Re: No wireless after resume from suspend

    I fixed the issue by doing this:

    Code:
    sudo vi /etc/pm/config.d/unload_modules
    and than adding this to file

    Code:
    SUSPEND_MODULES="$SUSPEND_MODULES ath_pci"
    The value ath_pci is kernel driver for my wifi which you can find by typing

    Code:
    sudo /sbin/lspci -v
    and then searching for "Ethernet controller" which in my case looks like this:

    Code:
    05:00.0 Ethernet controller: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01)    Subsystem: Askey Computer Corp. WLL3141 (Toshiba PA3613U-1MPC) 802.11bg Wireless Mini PCIe Card
        Flags: bus master, fast devsel, latency 0, IRQ 18
        Memory at f8000000 (64-bit, non-prefetchable) [size=64K]
        Capabilities: [40] Power Management version 2
        Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit-
        Capabilities: [60] Express Legacy Endpoint, MSI 00
        Capabilities: [90] MSI-X: Enable- Count=1 Masked-
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [140] Virtual Channel
        Kernel driver in use: ath_pci
    At the end you can see that my kernel driver in use is ath_pci (in bold)

    Thank you vazhavandan for your interest into this post.
