No wireless after resume from suspend

English Hardware

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…

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.

If you are using Network manager instead of ifup then you may need to run after network service. Then again i might be wrong :\

systemctl  restart NetworkManager.service

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

I fixed the issue by doing this:

sudo vi /etc/pm/config.d/unload_modules

and than adding this to file

SUSPEND_MODULES="$SUSPEND_MODULES ath_pci"

The value ath_pci is kernel driver for my wifi which you can find by typing

sudo /sbin/lspci -v

and then searching for “Ethernet controller” which in my case looks like this:

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

    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.
