Hi, I am using a device based on the Atheros QCA9882 chipset.
I would like to make use of the simultaneous dual-band functionality that the device provides. The goal is to have to interfaces with one acting as an Access Point (wlan0) and the other acting as a client of another AP (wlan1). Ideally, both of these interfaces should be operating on different channels. As I have understood it, Atheros/Qualcomm market the QCA9882 as being capable of both dual-band and concurrent operation: https://www.qualcomm.com/news/releases/2012/02/23/qualcomm-atheros-launches-80211ac-product-ecosystem-provide-end-end-gigabit I am using v4.1 of the Linux kernel. Having experienced some difficulties using hostapd and wpa_supplicant, I checked the device capabilities using iw. If I am interpreting the output below correctly, it is only possible to use 1 channel on both interfaces: valid interface combinations: * #{ managed, P2P-client } <= 36, #{ P2P-GO } <= 3, #{ AP } <= 7, #{ IBSS } <= 1, total <= 36, #channels <= 1, STA/AP BI must match As I understand it, #channels <=1 indicates that only 1 channel may be used at a particular time by all interfaces. I am wondering if this is a limitation of the driver, or if there has been a misunderstanding in the capabilities of the hardware. Does anyone have experience with this?
