	`注意 1:` 開機時WZR-HP-AG300H的bootloader大約4秒後的10-20秒、可以接收TFTP傳輸的韌體檔案 `注意 2:` 建議使用Linux系統連線!! `注意 3:` 網路線請接 PC =⇒ Switch =⇒ WZR-HP-AG300H

以下使用Lubuntu來做安裝範例

安裝TFTP連線軟體

sudo apt-get update
sudo apt-get install tftp-hpa

請確定WZR-HP-AG300H是電源關閉的
先停用電腦的網路服務

sudo /etc/init.d/networking stop

更改網路設定

sudo ifconfig eth0 192.168.11.2
sudo ifconfig eth0 netmask  255.255.255.0
sudo arp -s 192.168.11.1 02:AA:BB:CC:DD:20

啟動網路服務

start networking

使用tftp連線

tftp 192.168.11.1

設定tftp的設定

tftp> verbose
tftp> binary
tftp> trace
tftp> rexmt 1
tftp> timeout 360
tftp> put openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-tftp.bin

將WZR-HP-AG300H接上電源
如果紅色的DIAG LED在閃爍、表示WZR-HP-AG300H正在接收韌體、接收完成會自動重新開機
第一次登入請參考這裡

開啟網路瀏覽器連線到 http://192.168.11.1 and go to “Administration” → “Firmware Upgrade”
到“Administration” =⇒ “Firmware Upgrade”
上傳OpenWRT韌體
讓電腦自動取得OpenWRT新的IP位置
請參考checks_and_troubleshooting 第一次安裝

→ generic.sysupgrade

Basic configuration 設定您的Internet連縣，配定無線網路，USB 等設定

→ failsafe_and_factory_reset

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

如果你要插上USB裝置觸發LED 請增加 /etc/config/system

`config 'led' option 'default' '0' option 'name' 'USB' option 'sysfs' 'buffalo:red:diag' option 'trigger' 'usbdev' option 'dev' '1-1'`

你的設備不太可能會變磚，請先試試用TFTP的方法，如果還是不行、用較為進階的方式

怎麼連接串列阜:

打開機殼
在Movie Engine開關附近有串列阜的接點
從那“方形”接點開始是 vcc, gnd, tx, rx
Sends at 115200 8N1 as shipped
電壓是 3.3 V
