Atheros AR2425 dhcp issues [SOLVED]
  • ms3811ms3811 August 2010
    My Dell laptop has a Atheros 2425 chipset wireless card. Slitaz automatically detected and installed the driver for it (ath5k), but I cannot seem to get it to connect to the wireless router. Udhcpc simply keeps sending discovers with no luck. I read in many places that there is an issue with this card with most Linux kernels. There appears to be a solution (http://madberry.org/2008/08/how-to-get-atheros-ar242x-wireless-to-work-2/), but that requires compiling the driver (not too comfortable with that).

    Does anyone know of another solution to this issue?

    Ps: The router is configured for WPA2-Personal.

    lspci | grep Atheros returns:

    0c:00.0 Network controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)

    dmesg | grep Atheros returns:

    anybody?

    can you give the output of 

    iwlist wlan0 scan
    or whatever your wlan is named like wlan0 eth1....
  • ms3811ms3811 September 2010
    it randomly alternates between:

    wlan0 No scan results

    and

    wlan0 Interface doesn't support scanning : Device or resource busy

    it seems, that the module is not loaded - check with lsmod if ath5k is present - if not load it as root with modprobe ath5k
  • Trixar_zaTrixar_za September 2010
    If it's not being loaded, you have to added it @ menu--->system tools--->control box--->initailization--->load modules

    This should load ath5k module everytime the machine is started now.
  • ms3811ms3811 September 2010
    I'm quite sure it is loading, I remember checking with lsmod to see if ath5k is present. in any case I'll confirm, also it's definitely in rcS.conf.
  • ms3811ms3811 September 2010
    so yes, it is loaded, I also tried rmmod ath5k, then modprobe ath5k, then network.sh restart, just to be sure. This is the output of network.sh restart:

    Stopping all interfaces
    Killing all daemons
    killall: udhcpc: no process killed
    Shutting down wifi card
    Configuring wlan0...
    Starting wpa_supplicant for WPA-PSK...
    Starting udhcpc client on: wlan0...
    Selected interface 'wlan0'

    Typically after the above, atleast with my other laptops that use wl, in a few seconds udhcpc will procure an ip address. However, with this laptop that never happens.

    One other thing that's a bit unusual. ifconfig outputs three interfaces, 1. the default loopback adapter, 2. wlan0 and 3. wmaster0. Now I have never seen wmaster0 anywhere else except with this laptop. This interface has the same MAC as wlan0 except the MAC is followed by quite a few 00-00-00s. The Link encap says UNSPEC. Not sure if this is helpful, but thought I would mention it.

    Thanks for taking the time.

    any ideas where I can look next?
  • kultexkultex September 2010
    what I would do - take another distro and look if and how it is working there
  • ms3811ms3811 September 2010
    ouch! that laptop has a lot of stuff on it. I've been using it for awhile with a wired connection.

    In the post,

    jozee has a fix, but its for the Ar8132 chipset. I need something similar. Maybe I will just have to compile the driver for this box -- just that compiling stuff is really not my cup of tea. I've done it before, so I guess it's time to do it again :(!
  • ms3811ms3811 September 2010
    ok, this is kinda embarrassing. Turns out the wireless radio was off :|!!!

    So I turned it on by pressing [Fn]+[F11] (button with the wireless antenna icon), then restarted network and bingo.

    Sorry for wasting everyone's time and thanks for taking the trouble to try and help.
