    Wireless Fedora 19 iwlwifi wlan0 can't connect to wifi


    Hello;

    I have had some problems trying to get wlan0 wireless connecting to my WPA2 PSK network. NetworkManager can't figure it out yet the same lapop with Ubuntu starts up wlan on install. Why is wireless such a weakness of Fedora? Hardware works out of the box. So I turned off Network Manager and went to wlan0 and eth0 configs

    I can see my network this is output form iwlist wlan0 scan

    Code:
    iwlist wlan0 scan
    wlan0     Scan completed :

                        IE: Unknown: DD0700E04C02022000
    I installed the Intel Centrino microcode from kernel.org
    based on iwlist
    Code:
    lspci | grep Centrino
    01:00.0 Network controller: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] (rev 34)
    I have a wpa_supplicant.conf file including my psk inside /etc/wpa_supplicant/wpa_supplicant.conf:
    Code:
    ctrl_interface=/var/run/wpa_supplicant
    ctrl_interface_group=wheel
    network={
            ssid="WNETWORK"
            #psk="lemonjam"
        psk=3easnotreally1a9ee759e4076c5696a397df22bcfa0e92dd0e5cf8aac0a84d7e9d8c6
    }
    And here is my ifcfg-wlan0 inside network-scripts:

    Code:
    DEVICE=wlan0
    ONBOOT=yes
    BOOTPROTO=dhcp
    HWADDR=58:91:cf:4d:48:29
    NETMASK=
    DHCP_HOSTNAME=
    IPADDR=
    TYPE=Wireless
    USERCTL=yes
    NETWORKING_IPV6=no
    PEERDNS=yes
    MODE=Managed
    Ok so can someone provide some useful insight? Please tell me if you want to see any other config files.

    Thanks,

    Dave

    that's for my Fedora 17 box, but hopefully the same module is available for 19.

    check dmesg output for hardware messages, too.

    and does dmesg report that this firmware loads properly? if it doesn't, or you're not sure, perhaps you can try the one(s) packaged in Fedora's repos?
