Hi, I'm struggling to figure out how to debug this, grateful for advice
I have a PCEngines Alix with a wlm200nx wifi card. This should have an
AR9220 chip in it and be detected by the ath9k driver. I have built my
own kernel using linux-3.15.10, however, the ath9k driver isn't
"recognising" or otherwise appearing to bind to the hardware, even when
ath9k is modprobe'd
lspci shows:
00:0c.0 "Class 0280" "168c" "0029" "168c" "2096"
dmesg, shows very little in addition, just a boot time:
pci 0000:00:0c.0: [168c:0029] type 00 class 0x028000
lsmod
ath9k 46564 0
mac80211 198136 1 ath9k
ath9k_common 5364 1 ath9k
ath9k_hw 327804 2 ath9k,ath9k_common
ath 11888 3 ath9k,ath9k_common,ath9k_hw
cfg80211 126984 4 ath9k,mac80211,ath9k_common,ath
Relevant bits of .config are:
CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K_BTCOEX_SUPPORT=y
CONFIG_ATH9K=m
CONFIG_ATH9K_PCI=y
CONFIG_ATH9K_AHB=y
CONFIG_ATH9K_DEBUGFS=y
# CONFIG_ATH9K_STATION_STATISTICS is not set
# CONFIG_ATH9K_WOW is not set
# CONFIG_ATH9K_HTC is not set
I see nothing in syslog when loading the module (well, just one line
"Calling CRDA to ..."). I have tried adding debug=0xfffffff module
parameter and that doesn't show anything additional.
I would be extremely grateful for help debugging this further. I'm not
sure how to debug the module loading to see why it's not recognising the
hardware.
Note, the same kernel is successfully loading and using a ralink USB
wifi device, so I don't believe I have completely borked wifi. rfkill is
disabled (but I don't believe that affects module loading and
binding?). Have I missed some firmware? Do I need some additional
module included?
Very grateful for any help
Thanks
Ed W
