Sure Arend, here in attach the capture file, I dont have time to clean it, so I send it to you as-is. Of course the capture was taken by BCM4313 in monitor. The AP is set to 11n *ONLY* (NO mixed mode b/g/n), bssid is 00:1f:a4:de:03:b2, filtering from that you will find all what you need. The sta is an ath9k (74:e5:43:93:56:82) from Windows, WPA encrypted, during the capture it was always connected and transferring (tcp,http, icmp, arp, dhcp, and so on..), I just did a reconnect 1 time to produce the setup frames you need. Fyi, here also the last part of dmesg output: [...] Loading modules backported from Linux version v3.13-rc2-0-gdc1ccc4 Backport generated by backports.git v3.13-rc2-1-0-gf69c248 cfg80211: Calling CRDA to update world regulatory domain bcma-pci-bridge 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 bcma-pci-bridge 0000:02:00.0: setting latency timer to 64 bcma: bus0: Found chip with id 0x4313, rev 0x01 and package 0x08 bcma: bus0: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x24, class 0x0) bcma: bus0: Core 1 found: IEEE 802.11 (manuf 0x4BF, id 0x812, rev 0x18, class 0x0) bcma: bus0: Core 2 found: PCIe (manuf 0x4BF, id 0x820, rev 0x11, class 0x0) bcma: bus0: Bus registered cfg80211: World regulatory domain updated: cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) cfg80211: (2402000 KHz - 2494000 KHz @ 40000 KHz), (N/A, 3000 mBm) cfg80211: (4910000 KHz - 5235000 KHz @ 40000 KHz), (N/A, 3000 mBm) NET: Registered protocol family 10 ADDRCONF(NETDEV_UP): eth0: link is not ready brcmsmac bcma0:0: mfg 4bf core 812 rev 24 class 0 irq 17 ieee80211 phy0: Selected rate control algorithm 'minstrel_ht' brcmsmac bcma0:0: brcms_ops_config: change power-save mode: false (implement) device mon0 entered promiscuous mode Regards, On Mon, Jan 13, 2014, at 10:57 AM, Arend van Spriel wrote: > On 01/13/2014 07:18 PM, Nikita N. wrote: > > Yes Arend, I confirm, 802.11 frames transmitted at 11n bitrate. > > The card looks 11n capable, as it handshakes allright from Windows with > > my router set to 11n only (beacon frames contain all HT tags as normal) > > But when I flip in monitor mode under Linux, only 11b/g frames are shown > > (Wireshark,no filter) > > Yes of course I can send you a capture, any particular frames do you > > want inside? > > - beacons > - setup connection (AUTH/ASSOC) > - some data transfers that would be aggregated. > > Regards > > > Regards > > > > On Mon, Jan 13, 2014, at 08:23 AM, Arend van Spriel wrote: > >> On 01/13/2014 10:30 AM, Nikita N. wrote: > >>> Hi All :) an issue for the maintainers of brcmsmac, or anybody who > >>> knows. > >>> Using module brcmsmac, when I flip my BCM4313 in monitor mode, it shows > >>> allright all frames sent in 11b and 11g mode, but the *11n* ones are NOT > >>> shown, maybe filtered out or not detected. > >>> Is that a known bug? > >>> If not, how can I set brcmsmac to show also 11n frames? > >> > >> What do you mean by 11n frames?
