Hi, first: Please CC me as I'm not subscribed to the list. I have the following wireless card: 04:02.0 Network controller: Atheros Communications Inc. AR9227 Wireless Network Adapter (rev 01) I can't set it to master mode, but this card should support it: server ~ # iwconfig wlp4s2 wlp4s2 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=19 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off server ~ # iwconfig wlp4s2 mode Master Error for wireless request "Set Mode" (8B06) : SET failed on device wlp4s2 ; Invalid argument. My kernel config should be correct: server linux # cat .config | grep ATH9K CONFIG_ATH9K_HW=y CONFIG_ATH9K_COMMON=y # CONFIG_ATH9K_BTCOEX_SUPPORT is not set CONFIG_ATH9K=y CONFIG_ATH9K_PCI=y # CONFIG_ATH9K_AHB is not set # CONFIG_ATH9K_DEBUGFS is not set CONFIG_ATH9K_RATE_CONTROL=y # CONFIG_ATH9K_HTC is not set server linux # cat .config | grep MAC80211 CONFIG_MAC80211=y CONFIG_MAC80211_HAS_RC=y CONFIG_MAC80211_RC_MINSTREL=y CONFIG_MAC80211_RC_MINSTREL_HT=y CONFIG_MAC80211_RC_DEFAULT_MINSTREL=y CONFIG_MAC80211_RC_DEFAULT="minstrel_ht" # CONFIG_MAC80211_MESH is not set CONFIG_MAC80211_LEDS=y # CONFIG_MAC80211_DEBUGFS is not set # CONFIG_MAC80211_MESSAGE_TRACING is not set # CONFIG_MAC80211_DEBUG_MENU is not set # CONFIG_MAC80211_HWSIM is not set I can scan for wireless networks and probably also connect to them (never tested because this is not an use case for me). Any ideas? Thanks in advance!
