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
