Dell Latitude E6530 with Intel Centrino Advanced-N 6205, connecting to an unencrypted access point 3m away. Pinging the access point gives 20% to 100% packet loss, 8 out of 10 days I tried. The access point is an Edimax router with 802.11n support. Loading Ubuntu LiveCD at the same conditions gives 0% packet loss, always. Some report similar problems, see replies to http://forums.freebsd.org/showthread.php?t=38685 How-To-Repeat: $ dmesg | grep -E "wlan|iwn" module iwn already present! iwn0: <Intel Centrino Advanced-N 6205> mem 0xf7600000-0xf7601fff irq 17 at device 0.0 on pci3 wlan0: Ethernet address: xx:xx:xx:xx:xx:xx $ grep -E "wlan|iwn" /boot/loader.conf if_iwn_load="YES" iwn4965fw_load="YES" iwn1000fw_load="YES" iwn5000fw_load="YES" iwn5150fw_load="YES" iwn6000fw_load="YES" iwn6000g2afw_load="YES" iwn6000g2bfw_load="YES" iwn6050fw_load="YES" wlan_wep_load="YES" wlan_ccmp_load="YES" wlan_tkip_load="YES" $ grep -E "wlan|iwn" /etc/rc.conf wlans_iwn0="wlan0" ifconfig_wlan0="DHCP" $ kldstat Id Refs Address Size Name 1 34 0xffffffff80200000 1323388 kernel 3 1 0xffffffff81549000 c6d2f0 nvidia.ko 4 2 0xffffffff821b7000 484f8 linux.ko 5 1 0xffffffff82200000 2ed08 iwn4965fw.ko 6 1 0xffffffff8222f000 53520 iwn1000fw.ko 7 1 0xffffffff82283000 54188 iwn5000fw.ko 8 1 0xffffffff822d8000 534a8 iwn5150fw.ko 9 1 0xffffffff8232c000 6fe80 iwn6000fw.ko 10 1 0xffffffff8239c000 6d5c8 iwn6000g2afw.ko 11 1 0xffffffff8240a000 71758 iwn6000g2bfw.ko 12 1 0xffffffff8247c000 739d0 iwn6050fw.ko $ ifconfig iwn0 && ifconfig wlan0 iwn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290 ether xx:xx:xx:xx:xx:xx nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: IEEE 802.11 Wireless Ethernet autoselect mode 11ng status: associated wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether xx:xx:xx:xx:xx:xx inet 192.168.2.103 netmask 0xffffff00 broadcast 192.168.2.255 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: IEEE 802.11 Wireless Ethernet DS/1Mbps mode 11ng status: associated ssid Palantir channel 13 (2472 MHz 11g ht/20) bssid xx:xx:xx:xx:xx:xx country US authmode OPEN privacy OFF txpower 13 bmiss 10 scanvalid 60 bgscan bgscanintvl 300 bgscanidle 250 roam:rssi 7 roam:rate 64 protmode CTS ampdulimit 32k ampdudensity 8 -amsdutx amsdurx shortgi wme $ ping 192.168.2.1 [...] 1076 packets transmitted, 30 packets received, 97.2% packet loss round-trip min/avg/max/stddev = 1.356/104.635/2008.506/396.671 ms
