Hello, I've just joined the list so don't know how to join the same thread so to indicate that it's the same matter I use the same subject. I am trying to make my "04:01.0 Ethernet controller: Atheros Communications Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01)" which is identified by ath5k as [ 10.356742] ath5k phy0: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43) [ 10.356748] ath5k phy0: RF5112B multiband radio found (0x36) work in master mode. I've patched /drivers/net/wireless/ath5k/base.c as was suggested, I even put a debug printk() to make sure the patched version is used: printk(KERN_ERR "ath5k_pci: AP PATCH APPLIED!!!\n"); hw->wiphy->interface_modes = BIT(NL80211_IFTYPE_STATION) | BIT(NL80211_IFTYPE_AP) | BIT(NL80211_IFTYPE_ADHOC) | BIT(NL80211_IFTYPE_MESH_POINT); in dmesg I do see this: [ 9.899231] ath5k 0000:04:01.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [ 9.899272] ath5k 0000:04:01.0: registered as 'phy0' [ 9.899275] ath5k_pci: AP PATCH APPLIED!!! [ 10.356742] ath5k phy0: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43) [ 10.356748] ath5k phy0: RF5112B multiband radio found (0x36) however it still doesn't work: # iwconfig wlan1 mode master Error for wireless request "Set Mode" (8B06) : SET failed on device wlan1 ; Invalid argument. Obviously I am missing something, but can't find what. Are there any other prerequisites?
