    Wireless Network Configuration?


    The network connection icon on the top right corner shows "no network connection" but I can see all the available wireless networks. With this I assume that driver is working fine and wireless connectivity is available without access point connectivity. Here is the output for iwconfig eth1
    Code:
    eth1      IEEE 802.11abgn  ESSID:""  
              Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
              Bit Rate=144 Mb/s   Tx-Power:24 dBm   
              Retry min limit:7   RTS thr:off   Fragment thr:off
              Power Managementmode:All packets received
              Link Quality=5/5  Signal level=-256 dBm  Noise level=-90 dBm
              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    Then I assume it is the problem of network configuration. When I right click to Edit Connections... there are 3 tabs available for the selected connection: Wireless, Wireless Security and IPv4 Setting. The Connect automatically option is selected and for the Wireless tab I have set the SSID and Mode: Infrastructure. The security in Wireless Security tab is set to WPA & WPA2 Personal and the password is set. For IPv4 Setting tab Method: Automatic (DHCP) is set. With this configuration when I apply to connect it asks again and again for "Authentication required by wireless network" with WPA & WPA2 Personal and password information but failed to connect. The configuration files looks like this:
    Code:
    /etc/sysconfig/network-scripts/ifcfg-eth1
    # Broadcom Corporation BCM43228 802.11a/b/g/n
    DEVICE=eth1
    BOOTPROTO=dhcp
    ONBOOT=no
    HWADDR=08:ed:b9:e1:4e:ec
    
    /etc/sysconfig/network
    NETWORKING=yes
    NETWORKING_IPV6=yes
    HOSTNAME=localhost.localdomain
    
    /etc/resolv.conf
    # No nameservers found; try putting DNS servers into your
    # ifcfg files in /etc/sysconfig/network-scripts like so:
    #
    # DNS1=xxx.xxx.xxx.xxx
    # DNS2=xxx.xxx.xxx.xxx
    # DOMAIN=lab.foo.com bar.foo.com
    I had disabled the SELinux and Firewall since SELinux was preventing NetworkManager (NetworkManager_t) "execute" to ./dnsmasq (dnsmasq_exec_t).

    Another issue is that when I try to save the Network Configuration (System->Administrator->Network) after editing the wireless device configuration it exits with an unhandled exception...
    Code:
    Component: system-config-network
    Version: 1.3.99.21
    Summary: TBf6c835f4 NCHardwareList.py:482:save:AttributeError: HwWireless instance has no attribute 'type'...
    Also I don't know what to set in Wireless Settings tab of wireless device configuration if I will be able to save it.

    With Windows 7 on the same system (dual boot) I have absolutely no issue in wireless connectivity with the following settings.
    IPv4 connectivity, Access Point, Security type: WPA2-Personal and Encryption: AES

    Please help to configure the wireless connection. Thanks.

    hi,

    what is your distro/release?

    if you are not afraid of terminal-based commands, i would recommend trying some lower level commands, just to try and isolate the problem.

    first of all, have two terminals up and running, logged in as root. in one of them you'll be wanting to dmesg every so often, to see what the kernel is saying.

    in the other terminal:

    first, attempt to stop NetworkManager, it is a pain in the arse:
    Code:
    /etc/init.d/NetworkManager stop
    this command is distro-dependent, and may fail. just let us know your distro and we'll try to sort out the right command.

    now do a wireless sweep, to see the wireless networks. this part should already be working, b/c you can see them in the GUI tool, but it is a sanity check:

    Code:
    iwlist eth1 scanning
    now associate w/your wireless network:
    Code:
    iwconfig eth1 essid mywifinetwork
    echo $?
    iwconfig eth1
    the 2nd command should return a 0 (which means the previous command exited successfully)
    the 3rd command should now hopefully show something like:
    Code:
    eth1     IEEE 802.11bgn  ESSID:"mywifinetwork"
    now attempt to authenticate to the wifi network using your key:
    Code:
    iwconfig eth1 key *******************
    see that it is there:
    Code:
    iwconfig eth1|grep key
    you can also pass mode, channel, and other settings to iwconfig, but usually those can be figured out automatically.

    now try and get an IP address from your AP/wifi router:
    Code:
    dhclient -d -v eth1
    the dhclient program will run in the foreground, and will spew info to the terminal. hopefully you will get your ip address relatively quickly. if not, it is time to check your AP/router. there should be a log somewhere on it that you can peruse. you need to make sure the DHCP is enabled on the router and that it is not MAC-filtering (or if it is, you need to add your client's MAC to the list).

    NOTE: I did not mention wpa_supplicant. You may need to use this to authenticate, I do not on my wifi networks, but it is worth mentioning, as others definitely have need this.

    report your progress up to this point.

    that's good, your wireless network adapter seems to be working - or at least is partially working.

    Code:
    # iwconfig eth1 essid blade
    # echo $?
    0
    it looks like you successfully associated your PC w/the "blade" network, okay.

    Code:
    # iwconfig eth1

    You might need to use wpa_supplicant instead of iwconfig for the command line authentication. see this answer to a thread discussing your authentication problem.

    i'm not sure what is wrong w/that dhclient command. it looks like to me. but anyway, it will fail until you get your wireless adapter to successfully associate w/your network.

    Thanks atreyu for your quick reply. For wpa_supplicant I followed instructions from here:

    I checked /etc/wpa_supplicant/wpa_supplicant.conf and it has the correct essid and key. What is going wrong?

    can you post your wpa_supplicant.conf file? obscure your key, of course. it may be you need slightly different syntax in your network stanza. take a look at the example wpa_supplicant.conf file included with your wpa_supplicant package. a copy is here.

    Code:
    # wpa_supplicant -B -Dwext -i eth1 -c /etc/wpa_supplicant/wpa_supplicant.conf
    (wext) Device eth1 kernel driver name: wl.
    Device eth1 kernel driver name: wl.
    try leaving off the -B so that it runs in the foreground. also, leave off the -Dwext as a test. add debugging, too - try this:

    Code:
    /usr/sbin/wpa_supplicant -c /etc/wpa_supplicant/wpa_supplicant.conf  -i eth1 -d
    Code:
    # dhcpcd eth1
    bash: dhcpcd: command not found
    you probably want "dhclient", not "dhcpcd"...but anyway, don't worry about that part until you can see your ESSID and KEY in the output of "iwconfig".

    Here is the content of wpa_supplicant.conf file:
    ======================================
    Code:
    network={
    	ssid="blade"
    	#psk="************"
    	psk=****************************************************************

    and this was the content of original wpa_supplicant.conf example file before editing:

    Code:

    There are two things I noticed, first the supported drivers for wpa_supplicant does not include broadcom... is that a problem? Secondly in my previous reply #5 when I used "iwconfig eth1" command it shows Frequency:5.6 GHz, is that correct?... I assume it should be 2.4 GHz.
    Please help.

    i wouldn't worry about the freq question, b/c in your output i see:

    Code:
    Trying to associate with 20:aa:4b:da:5d:ae (SSID='blade' freq=2462 MHz)
    so it is auto-negotiating that.

    regarding broadcom, good question, i didn't pay attention to that before. broadcom is quite finicky in Linux. Try this fairly straightforward tutorial on install a somewhat reliable driver for Broadcom-based chipsets in CentOS. Follow the instructions for EL5 (as you are on CentOS 5.9). If your existing driver is working okay, then perhaps it has to do with how you are providing the key (in wpa_supplicant.conf), but I do think your problem is driver/firmware related, at this point.

    also, you appear to be running the wpa_supplicant command twice; you don't want to do that. it should only be run once. and watch out for NetworkManager, b/c it will keep restarting it, if NM is running.

    After re-installing CentOS5.9 I followed the tutorial you suggested and the driver seems to install fine but the wpa_supplicant result is same.

    What should I do?... this is really frustrating. Can I use ndiswrapper instead?

    before you try NDISwrapper, one more thought: are you sure the kernel's default drivers for that chipset are not being loaded? check the output of lsmod. maybe this:

    Code:
    lsmod|egrep 'bcm43|b43'
    if you see any such modules, use rmmod to remove them. they can be blacklisted for the future, if this turns out to be the case. the only driver that should be binding to the NIC is the new one you compiled, wl.ko.
