TFTP安裝
 | 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
在DD-WRT下安裝
- 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”
- 讓電腦自動取得OpenWRT新的IP位置
- 請參考checks_and_troubleshooting 第一次安裝
升級OpenWrt
基本設定
Basic configuration 設定您的Internet連縣，配定無線網路，USB 等設定
救援模式
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.
其他特別設定
LED for USB裝置
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'

解磚
- 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

Notes
串列阜
→ port.serial 串列阜相關資訊
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
