在 FreeBSD 上配置無線網路：路由器顯示無線設備已連接，但無法 ping
我的問題與此類似。
我在 FreeBSD 10.3-STABLE 上配置我的 Broadcom BCM4311 802.11b/g 設備，如下所示：
sudo kldload if_bwn sudo kldload bwn_v4_ucode sudo kldload bwn_v4_lp_ucode # # Now, interface `bwn0` is available # sudo ifconfig wlan0 create wlandev bwn0 sudo ifconfig wlan0 up # at this moment, laptop WiFi LED light turns on sudo ifconfig wlan0 scan # I can see my wireless router SSID sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf sudo ifconfig wlan0 list sta sudo dhclient wlan0 # # Optionally, rather than dhclient run: # sudo ifconfig wlan0 inet 192.168.1.103 netmask 0xffffff00
ifconfig顯示關聯的無線網路狀態：$ ifconfig bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE> ether 00:15:c5:ad:63:9c inet 192.168.1.101 netmask 0xffffff00 broadcast 192.168.1.255 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect (100baseTX <full-duplex>) status: active lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6> inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2 inet 127.0.0.1 netmask 0xff000000 nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> bwn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290 ether 00:18:f3:38:a0:36 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: IEEE 802.11 Wireless Ethernet autoselect mode 11g status: associated wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:18:f3:38:a0:36 inet 192.168.1.103 netmask 0xffffff00 broadcast 192.168.1.255 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: IEEE 802.11 Wireless Ethernet OFDM/48Mbps mode 11g status: associated ssid Mine channel 11 (2462 MHz 11g) bssid e8:de:27:6b:3e:67 country US authmode WPA2/802.11i privacy ON deftxkey UNDEF TKIP 2:128-bit txpower 30 bmiss 7 scanvalid 60 bgscan bgscanintvl 300 bgscanidle 250 roam:rssi 7 roam:rate 5 protmode CTS wme roaming MANUAL $我通過以下方法斷開筆記型電腦乙太網電纜以檢查與路由器的無線連接：
無線路由器顯示我的筆記型電腦列在“目前連接的無線客戶端”中：
ID MAC 1 00:18:F3:38:A0:36無線路由器有一個診斷 ping 工具，我可以通過它 ping 到我的筆記型電腦，當我這樣做時，
timed out會收到消息：IP Address/Domain Name: 192.168.1.103 Request timed out從我的筆記型電腦我ping到路由器：

我不使用
/etc/rc.conf，我手動完成所有操作。我使用以下wpa_supplicant配置：$ cat /etc/wpa_supplicant.conf network={ ssid="Mine" psk=79a174594e2ec3563ff4c35c1a82a006b19df646fa020aaf53078d34d09ed962 } $我想知道是否有人可以伸出援助之手。
更新：
現在，我
/etc/rc.conf這樣使用：# # Kernel modules to load after local disks are mounted # kld_list="linux nvidia if_bwn bwn_v4_ucode bwn_v4_lp_ucode fuse" # # DELL LATITUDE | D820 # hostname="D820" # # $ sudo ifconfig wlan0 create wlandev bwn0 # wlans_bwn0="wlan0" # # $ sudo ifconfig wlan0 up # $ sudo ifconfig wlan0 scan # $ sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf # $ sudo dhclient wlan0 # wpa_supplicant_conf_file="/etc/wpa_supplicant.conf" ifconfig_wlan0="WPA DHCP" # # gnome3-lite desktop environment services # #dbus_enable="YES" #hald_enable="YES" #gdm_enable="YES" # GDM will start automatically when the system boots #gnome_enable="YES" #linux_enable="YES" ## ## To enable the tor server ## #tor_enable="YES" ## ## web proxy of choice ## #polipo_enable="YES" #privoxy_enable="YES" ## ##For Linux compatibility to be enabled at boot time ## linux_enable="YES"
當您啟動筆記型電腦並通過 配置有線
bge0介面時dhclient，它成為預設路由（如 輸出中最右邊的列所示netstat -r）。當您稍後配置無線bwn0介面並斷開有線介面時，它並未設置為預設路由。當您嘗試訪問網路（或回復請求）時，流量正在嘗試使用bge0但已斷開連接。重新啟動您的筆記型電腦，您只需配置無線介面就不會出現此問題。
如果你將來想從有線轉向無線，我相信你可以做到以下幾點：
route change default -iface wlan0 route change default 192.168.1.1這會將預設路由介面設置為無線介面，這會重置路由器地址，因此我們在第二行重新添加它。
