Re: WiFi configuration
Hi, It's a hold-over from what wifi will let you get away with. Just stick to 1500 and let the 802.11n A-MPDU aggregate things as appropriate. -a On 24 February 2014 00:56, Michael BlackHeart wrote: > > > > 2014-02-24 10:35 GMT+04:00 Adrian Chadd : > >> Hi >> >> all you need is: >> >> interface=wlan0 >> driver=bsd >> ssid=CACHEBOY_11N_1 >> wpa=3 >> wpa_key_mgmt=WPA-PSK >> wpa_passphrase=PasswordGoesHere >> wpa_pairwise=CCMP >> ctrl_interface=/var/run/hostapd >> >> >> I haven't tried running the wifi with an mtu greater than the default >> (1500).

Look at this ath0: flags=8843 metric 0 mtu 2290 ether cc:b2:55:00:68:1f media: IEEE 802.11 Wireless Ethernet autoselect mode 11ng status: running But when freebsd creates wlan0 it's lowered to 1500. I tried with another ath WiFi card this way - worked fine with 2290 MTU in a bridge. BTW 2290 is max value, but it seems than noone looked into wifi MTU under freebsd, theoretically it could be about 7k to 9k - normal jumbo frame. 2290 is some kinda way of baby jumbo frames - they're slightly bigger than 1.5k. So next is the bridge. By default bridge uses the MTU of a first member, so if it will be a stock ethernet i-face so it'll be again 1500. If you're asking me why am I to use increased MTU - I see it reasonable. > you also don't need to say ht, it'll automatically do ht for you. > > -a > -- amd_miek Think different.

Re: WiFi configuration
Hi all you need is: interface=wlan0 driver=bsd ssid=CACHEBOY_11N_1 wpa=3 wpa_key_mgmt=WPA-PSK wpa_passphrase=PasswordGoesHere wpa_pairwise=CCMP ctrl_interface=/var/run/hostapd I haven't tried running the wifi with an mtu greater than the default (1500). Why are you trying to do this? you also don't need to say ht, it'll automatically do ht for you. -a ___ freebsd-wireless@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "freebsd-wireless-unsubscr...@freebsd.org"
WiFi configuration
Hello, I've got a question about configuring WiFi bridged networking in FreeBSD 10 Stable. The config info: *Ethernet and WiFi transparent bridged network *WiFi is protected via WPA2 *802.11n/ht WiFi FreeBSD Configuration: wlans_ath0="wlan0" create_args_wlan0="wlanmode hostap" cloned_interfaces="bridge0" ifconfig_lo0="inet 127.0.0.1/8 mtu 9000" ifconfig_bridge0="inet 192.168.1.1/24 addm re1 addm wlan0 description LAN" ifconfig_re0="rxcsum txcsum tso -vlanhwtag -vlanmtu -vlanhwcsum description ToISP up" ifconfig_re1="description LAN_Ethernet" ifconfig_wlan0="ht channel 6:ht/20 country RU regdomain etsi -bgscan bintval 500" Hostapd from ports: In rc.conf hostapd_enable="YES" hostapd_program="/usr/local/sbin/hostapd" In /etc/hostapd.conf there's some stuff configured interface=wlan0 driver=bsd logger_syslog=-1 logger_syslog_level=4 logger_stdout=-1 logger_stdout_level=4 dump_file=/tmp/hostapd.dump ctrl_interface=/var/run/hostapd ctrl_interface_group=wheel ssid=MIEKOFF.LOCAL country_code=RU ieee80211d=1 beacon_int=100 dtim_period=2 max_num_sta=10 rts_threshold=2347 fragm_threshold=2346 preamble=1 macaddr_acl=0 auth_algs=2 ignore_broadcast_ssid=0 wmm_enabled=1 wmm_ac_bk_cwmin=4 wmm_ac_bk_cwmax=10 wmm_ac_bk_aifs=7 wmm_ac_bk_txop_limit=0 wmm_ac_bk_acm=0 wmm_ac_be_aifs=3 wmm_ac_be_cwmin=4 wmm_ac_be_cwmax=10 wmm_ac_be_txop_limit=0 wmm_ac_be_acm=0 wmm_ac_vi_aifs=2 wmm_ac_vi_cwmin=3 wmm_ac_vi_cwmax=4 wmm_ac_vi_txop_limit=94 wmm_ac_vi_acm=0 wmm_ac_vo_aifs=2 wmm_ac_vo_cwmin=2 wmm_ac_vo_cwmax=3 wmm_ac_vo_txop_limit=47 wmm_ac_vo_acm=0 ap_max_inactivity=600 disassoc_low_ack=1 max_listen_interval=600 ap_isolate=0 ieee8021x=0 eap_server=0 wpa=2 wpa_psk=da55ab74e575db9fcfa6dca52dbe9c1d29cc8a216627b0360e91c4ff3a50b6f9 wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP CCMP wpa_group_rekey=600 wpa_gmk_rekey=86400 rsn_preauth=1 disable_pmksa_caching=0 ap_table_max_size=255 ap_table_expiration_time=3600 time_advertisement=0 Question 1: Should I use hostapd from world or ports? Does it matter? Question 2: It seems than order of lines in rc.conf is important, e.g. if I place wifi before bridge there wolud be an error. Question 3: how should I configure WiFi device to be 802.11n/ht capable? When I place some args in "wlan_create" line they do not work or produce errors. e.g. if I place this: create_args_wlan0="wlanmode hostap ht channel 6:ht/20 country RU regdomain etsi mtu 2290" WiFi device would be not condigured due to unknown reason while system boots up. Question 4: I'd like to have increased MTU (2290), but when I try to add some MTU stuff to configuration, the bridge0 starts first, adds re1 with increased MTU and says that it cannot attach wlan0 with MTU 1500. Question 5: something happens with ht/40+. I just figure out how to configure wlan0 with ht/40+ at the boot time. When I add it to wlan_create nothing happens or error happens. Of couse each try breaks bridge0 and cuts me off so I have to log in directly - that's pain. Question 6: what sould I configure in hostapd.conf? Or what can I configure if I'd like to without disturbing wireless networking. -- amd_miek Think different.
