Hello community, Im using a Wifi AP with an Atheros card now for quite some time, since a couple of FreeBSD revisions. I guess started back on FreeBSD 10(?). My wifi AP seem to limit me to 2MB/s basically, which is pretty slow. Im not sure if all my options are ok, or if there are some ways I can tweak around it... Is this a limitation of the current driver? Would be very interesting to hear from someone who runs a similar setup and has more speed/throughput than I do. I only have this box with this card, cant really tinker a lot around with other cards - and as I know Atheros is one of the drivers which is better supported than others. Back then it was quite hard to get 5GHz running correctly.... Some of my debug output, config files etc.: -------------------------------dmesg-ath------------------------------- ath0: <Atheros 9280> mem 0xfe800000-0xfe80ffff at device 0.0 on pci4 [ath] enabling AN_TOP2_FIXUP ath0: [HT] enabling HT modes ath0: [HT] 1 stream STBC receive enabled ath0: [HT] 1 stream STBC transmit enabled ath0: [HT] 2 RX streams; 2 TX streams ath0: AR9280 mac 128.2 RF5133 phy 13.0 ath0: 2GHz radio: 0x0000; 5GHz radio: 0x00c0 -------------------------------dmesg-ath------------------------------- -------------------------ifconfig-wlan0-------------------------------- wlan0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether XX:XX:XX:XX:XX:XX hwaddr XX:XX:XX:XX:XX:XX nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: IEEE 802.11 Wireless Ethernet autoselect mode 11na <hostap> status: running ssid XXXXXXXXXXX channel 40 (5200 MHz 11a ht/20) bssid XX:XX:XX:XX:XX:XX regdomain ETSI country DE ecm authmode WPA2/802.11i privacy MIXED deftxkey 2 AES-CCM 2:128-bit AES-CCM 3:128-bit txpower 17 mcastrate 6 mgmtrate 6 scanvalid 60 ampdulimit 64k ampdudensity 8 shortgi wme burst dtimperiod 1 -dfs groups: wlan -------------------------ifconfig-wlan0-------------------------------- As you can see Im using "country DE" - but this cant be the reason for such slow speed? -------------------------rc.conf-------------------------------------- create_args_wlan0="wlanmode hostap channel 40:ht/20 country de" -------------------------rc.conf-------------------------------------- ------------------------hostapd.conf---------------------------------- interface=wlan0 ctrl_interface=/var/run/hostapd ctrl_interface_group=0 ssid=XXXXXXXXXXXXXXXXXXXXXx wmm_enabled=1 ieee80211d=1 country_code=DE wpa=2 wpa_passphrase=XXXXXXXXXXXXXXXX wpa_key_mgmt=WPA-PSK wpa_pairwise=CCMP rsn_pairwise=CCMP ------------------------hostapd.conf---------------------------------- best regards, -- Georg Bege Mail: georg@bege.email IRC: megaTherion @ Freenode
