Thread: Suse 11.4 can't find wireless network (ath5k)

    Default Suse 11.4 can't find wireless network (ath5k)

    I'm running OpenSuse 11.4 with kernel (2.6.37.1-1.2-desktop i686) and KDE 4.6.00 "release 6".

    When I first installed the system the KNetworkManager found my wireless network. After entering my details it suddenly couldn't find it any more and hasn't found it since (even after re-install). My network is definitely working.

    Below are the outputs as suggested in the stickies.

    /sbin/lspci -n

    I did try and set it up with ifup but it still couldn't find any network.
    Unfortunately I don't know anything about networks even less about wireless ones. Many thanks in advance.

    Ok, I believe my problem has something to do with the fact some rfswitch is set. I tried unblocking ath5k with rfkill...no result still hard and soft blocked.

    I also tried installing madwifi but I have the same problem. I can't enable wifi.

    Change your switch from off to on.

    Change your switch from off to on.
    Do I do this with "rfkill unblock all"? That doesn't work for me. It stays blocked.

    PS: I'm using madwifi now. I had a short lived success earlier, but I didn't do anything different. Just kept typing the command in the hope it would change. Suddenly I had wifi...for 5 minutes. Until I did a restart to check whether it was for real.

    You cannot unblock a hard block with rfkill. You have to activate the switch
    either with the physical switch or the fn key. If you have the latter, use
    Google to find the wmi module for your brand.

    Thank you very much...I didn't realise the led key would work, because it doesn't change colour. On madwifi it's constantly orange and with the ath5k it's always blue. I'm used to it changing colour, depending on the wireless state.
    I'll be reverting back to ath5k to see if the wireless will work out of the box, now that I know about the button...thanks again, for nudging me in the right direction.

    Hi everyone!

    I have the same problem, but I couldn't understand the solution explained in here, may anyone rephrase it to me? please

    lspci -k

    07:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)
    Subsystem: Hewlett-Packard Company Device 137a
    Kernel driver in use: ath5k
    lsmod | grep ath5k

    ath5k 142052 0
    ath 15984 1 ath5k
    mac80211 265888 1 ath5k
    cfg80211 151799 3 ath5k,ath,mac80211


    at first I thought it was Networkmanager, so I uninstalled it and tried manually with ifup, but I didn't get any good result with it.

    thanks in advance!!!

    In general, don't piggy back threads.
    The solution was to check rfkill
    Code:
    sudo zypper in rfkill
    rfkill list
    to see if anything was blocked. His wireless had a hard block. That is fancy for "his switch was off" So he flipped the switch and voila he had wi-fi. There was also a driver re-install which may/may not have been necessary.

    I installed rfkill as you mentioned it, however I don't know how to "flip" the switch on :-( could you give me a hand here? please

    Code:
    0: hp-wifi: Wireless LAN
            Soft blocked: yes
            Hard blocked: no

            Soft blocked: yes

    The switch is a "hard" block. That is not your problem.

    Try 'rfkill unblock wifi'.
