    Problem setting up my wireless interface with an arch install


    I am having issues setting up my wireless interface during the arch install on my cheap HP CQ60-419wm laptop. Unfortunately my wireless interface has always been weird and semi flaky and difficult to configure even with a hand holding OS like windows. What i have done so far is:

    I start of stating i have two Ethernet controllers: One wired NVIDIA controller and one wireless Atheros controller

    Code:
    lspci |grep -i net 
    
    00:0a.0 Ethernet controller: NVIDIA Corporation MCP77 Ethernet (rev a2)
    07:00.0 Ethernet controller: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01)
    I followed the beginners guide wiki

    even though my hardware indicator light is lit iwconfig produces

    Code:
    eth0 no wireless extension.
    lo no wireless extension.
    
    wlan0 IEEE 802.11bg ESSID:off/any
    Mode:Managed Access Point:Not-Associated Tx-Power=off
    Retry long limit:7 RTS thr:off Fragment thr:off
    Encryption key:off
    Power Management:on
    When i try to set up my wlan0 using
    Code:
    ip link set wlan0 up
    
    which produces
    RTNETLINK answers: Operation not possible due to RF-kill
    So i use rfkill list all which produces the following:
    (also note I am an intermediate linux user who wishes to learn more and i have never used wireless on linux and i do not know exactly what this information means i just can just view the results)
    Code:
    0: hp-wifi: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
    
    1:phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
    I use rfkill unblock all which changes the result of rfkill list all and allows the successful usage of ip link set wlan0 up which inturn changes the results of iwconfig
    Code:
    0: hp-wifi: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
    
    1:phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    
    
    wlan0 IEEE 802.11bg ESSID:off/any
    Mode:Managed Access Point:Not-Associated Tx-Power=20 dBm
    Retry long limit:7 RTS thr:off Fragment thr:off
    Encryption key:off
    Power Management:on
    now i use wifi-menu wlan0 and this is where i start to hit my head against a wall

    running that returns either No network found or interface unavailable..
    I googled this problem and tried to a few things such as rmmod hp-wmi to remove the wired controller driver, i have reloaded the ath5k driver and no matter what i can get the interface to work.. Also if my interfaced gets hard blocked i cant seem to unblock it with the physical button.

    I would love some advice.

    I've seen other threads like this and they had to blacklist the HP driver. if you do a little of searching around for this you should get it working.
