【韌體】貝爾金 Belkin F5D7230-4 v1444 韌體更新
前幾天把一台貝爾金 Belkin F5D7230-4 v1444 韌體更新到DD-WRT V23-SP2 micro generic 版, 趁著記憶猶新把過程記錄下來, 資料參考:
[INDENT][URL="http://www.dd-wrt.com/wiki/index.php/Installation#Belkin_F5D7230-4_v2xxx_and_Lower"]5.9 Belkin F5D7230-4 v2xxx and Lower - Installation - DD-WRT Wiki[/URL][/INDENT]
小弟改刷DD-WRT 的最主要目的在於無線功率調整, 至於刷成功後, 預設連線數僅512, 這應該是受限於只有8MB 記憶體, 所以建議降低UDP time out, 以便迅速釋放記憶體
由於沒另外準備交換器, 所以小弟已經預期會遇上Windows 網卡 "[B]備妥[/B]" 的問題, 此問題小弟也曾在其他文章提及, 主要就是網卡和分享器實體連接之後, Windows 仍需數秒鐘的時間建立TCP/IP 連線, 其中主要花在[B]Link Speed & Duplex Negotiation[/B] 和[URL="http://support.microsoft.com/kb/239924"][B]Windows TCP/IP Media Sensing[/B][/URL], 前者可由網卡的進階內容調整, 後者可由登錄檔修改, 由於DD-WRT 安裝教學已經確定TFTP 可行, 所以小弟並未嘗試以原廠Web GUI 升級, 以免節外生枝
首先小弟研判[B]Media Sensing[/B] 的影響可能比較大, 所以先把它關閉, 再斷開WAN, 並重置分享器回到出廠預設值, 網卡設定成Dual-IP "192.168.1.2/24" & "192.168.2.2/24", 前者用於升級DD-WRT 成功之後, 後者為暫時針對Belkin 原廠韌體, Multi-IP 可由TCP/IP 的進階內容設定, Windows 桌面上一共開啟三個視窗, 瀏覽器登入Belkin Web GUI 192.168.2.1, 用來觀察分享器重啟過程, "[URL="http://www.kwakkelflap.com/fping.html"][B][COLOR="Red"]f[/COLOR][/B]ping[/URL]" 密集連續ping 192.168.2.1, DD-WRT 網友tornado 修改過的[URL="http://www.dd-wrt.com/dd-wrtv2/downloads/others/tornado/Windows-TFTP/tftp2.exe"]Linksys tftp2.exe[/URL] 則準備好以DD-WRT V23-SP2 micro generic 版韌體刷新, 由於原廠CFE Boot_Wait 可能只有1~2 秒之間, 所以用此方法必須眼明手快, 先由Web GUI 重新啟動分享器數次, 觀察fping 結果的變化, 看起來應該類似於:

18:55:10 : 192.168.2.1: request timed out
18:55:10 : 192.168.2.1: request timed out[/INDENT]
以上可看出CFE 啟動約需2~3 秒, Boot_Wait 大約有1 秒, 掌握節奏之後, 於 "[B]request timed out[/B]" 又重新 "[B]Reply[/B]" 之際, 立刻按下tftp2 "Upgrade", 此法嘗試了數次, 都不成功, 肯定仍然超過CFE 等候的時間, 於是又手動調整網卡速率為 "[B]10Mbps/Full Duplex[/B]", 接著便一試成功
小弟以[B]Web GUI Reboot[/B] 取代分享器關機再開 ([B]Power Cycle[/B]) 的理由是盡量減少對於網卡 "備妥" 的影響, 這點可由 "fping" 結果看出, 以下是小弟針對此流程所寫的韌體自動TFTP 更新批次檔, 請將[COLOR="Red"][B]fping.exe, 韌體以及此批次檔[/B][/COLOR]複製於同一個資料夾, 執行此批次檔之前, 請先登入分享器的Web GUI, 以下未經嚴格測試, 考慮未免不夠周詳, 敬請不吝批評指教
