According to the spec, a VHT STA must support 80 MHz: 802.11ac-2013, 22.1.1: A VHT STA shall support the following features: [...] - 20 MHz, 40 MHz, and 80 MHz channel widths Consequently, there's no bit indicating whether or not 80 MHz bandwidth is supported (like there is, for VHT, indicating 40 MHz is supported or not.) Also it is invalid to advertise a VHT capabilities IE and an HT capabilities IE without 40 MHz. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
