Raspberry Pi 安裝USB無線網卡 (Buffalo WLI-UC-GNM)

安裝USB無線網卡

執行lsub確認Raspberry Pi已經抓到USB無線網路卡。範例為Buffalo WLI-UC-GNM無線網卡。

> lsusb

執行結果：

Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 0411:01a2 BUFFALO INC. (formerly MelCo., Inc.) WLI-UC-GNM Wireless LAN Adapter [Ralink RT8070]

確實抓到網卡(Ralink RT8070相容驅動程式)。

編輯網路介面設定檔案

> vi /etc/network/interfaces

auto lo
iface lo inet loopback

# 設定Ethernet網卡以DHCP取得IP
iface eth0 inet dhcp

# 設定Ethernet網卡以DHCP取得IP
allow-hotplug wlan0
iface wlan0 inet dhcp

# 強制網卡以WPA2方式與Wi-Fi AP連線
wpa 2

# 設定Wi-Fi AP 之SSID與密碼
wpa-ssid <<YOUR_SSID>>
wpa-psk <<YOUR_WPA2_PSK_PASSWORD>>

重新啟動networking

> service networking restart



確認網卡已配置IP

> ifconfig -a
