手上有2B,也剛好有個3B的板載無線沒反應(yīng)壞掉了，就學(xué)如何安裝USB 無線網(wǎng)卡

EDUP EP-8508GS

• 1、EDUP EP-8508GS支持11n標(biāo)準(zhǔn)也讓無線暢游更加出色。
• 2、采用REALTEK 8188cus芯片802.11n無線傳輸技術(shù)，傳輸速率高達(dá)150Mbps

確認(rèn)你的Kernel支持那些無線網(wǎng)卡:這款是我的網(wǎng)卡 realtek/rtl818x/rtl8187/rtl8187.ko

第一行的Realtek設(shè)備就是無線網(wǎng)卡.

查看Kernel載入的模塊:

sudo nano /etc/network/interfaces

# wifi (dhcp config) : auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

sudo nano/etc/wpa_supplicant/wpa_supplicant.conf, 增加如下幾行:?

network={???ssid=“WIFI名稱“proto=WPA2key_mgmt=WPA-PSKpairwise=TKIPgroup=TKIPpsk=”WIFI密碼“}

這里存的是明文密碼, 如果需要存儲加密后的密碼, 執(zhí)行命令wpa_passphrase ssid password, 替換上面的psk密碼.
wpa_supplicant.conf里面更多參數(shù)詳情, 請參考man手冊鏈接, 上面的配置能應(yīng)付大多數(shù)路由器了.

重啟wlam0

重啟無線網(wǎng)卡: sudo ifdown wlan0(關(guān)閉)

sudo ifup wlan0(啟動)
然后運行ifconfig wlan0 查看無線網(wǎng)卡是否獲能夠取到了IP.

?

?

安裝完成之后，創(chuàng)建一個配置文件，輸入如下命令：

$ sudo nano /etc/wpa.conf

將下列內(nèi)容復(fù)制進去：

network={
ssid="你用的WIFI的SSID"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="WIFI的密碼"
}

接下來編輯網(wǎng)絡(luò)配置文件：

sudo nano /etc/network/interfaces

?

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa.conf? <---增加此行
#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf?? <---注釋掉此行
iface default inet dhcp

保存，退出。

重啟樹莓派，記得拔掉網(wǎng)線，它將自動連上無線網(wǎng)絡(luò)。

之后，若要換無線網(wǎng)，只需要編輯/etc/wpa.conf中的ssid和psk即可。
