自 ASUS RT-N16 推出以來，採用 Broadcom 旗下 BCM 4718 晶片，這家晶片在過去被許多第三方韌體組織廣泛支援，加上原廠韌體穩定性一直保有很大的改善空間，使得向來潛藏的第三方韌體更加活絡起來。所以當 ASUS RT-N16 推出不到半年，市場上已經出現三套能直接支援 ASUS RT-N16 的第三方韌體。
而各家韌體皆有其專精獨到之處，例如 DD-WRT 內建支援多國語言，強調友善的管理介面。Tomato(teddy bear mod) 著重在 USB 介面及 QoS 的支援，在台灣很多死忠粉絲。LLY 則延續了老牌 Oleg 韌體的香火，提供網友一個簡單而直覺的改機環境。一般網友大多只能根據網路上討論來決定是否該刷韌體或該刷哪一家韌體，本文不詳細評論各家優劣，我們只針對網路傳輸效能部分做測試，希望此舉也能印證在同樣的硬體下，搭配不同的韌體對效能的影響程度，提供網友日後改機參考。

下圖是將各項測試數據整理後，所產生的圖表，我們可以很明確看得出來 ASUS 原廠韌體的 NAT 效能像是擁有獨家祕技似的，大幅領先其他家韌體，不過在 WLAN 部分的效能卻只能稱作笑能，把 N 當 G 用，明顯落後其他韌體。其他第三方韌體 LLY、DD-WRT 及 Tomato 或許少了 Broadcom 直接傳授的獨家密技，各項數據表現都在伯仲之間，相較之下，LLY 韌體各項效能表現穩定領先，以綜合各項效能的評估是較值得推薦的韌體。語法:ds209> iperf -c 192.168.1.1 -w 128k -t 60 -P 5 ------------------------------------------------------------ Client connecting to 192.168.1.1, TCP port 5001 TCP window size: 212 KByte (WARNING: requested 128 KByte) ------------------------------------------------------------ [ 7] local 192.168.1.50 port 49437 connected with 192.168.1.1 port 5001 [ 3] local 192.168.1.50 port 49433 connected with 192.168.1.1 port 5001 [ 4] local 192.168.1.50 port 49434 connected with 192.168.1.1 port 5001 [ 5] local 192.168.1.50 port 49435 connected with 192.168.1.1 port 5001 [ 6] local 192.168.1.50 port 49436 connected with 192.168.1.1 port 5001 [ ID] Interval Transfer Bandwidth [ 4] 0.0-60.0 sec 204 MBytes 28.5 Mbits/sec [ ID] Interval Transfer Bandwidth [ 5] 0.0-60.0 sec 200 MBytes 27.9 Mbits/sec [ ID] Interval Transfer Bandwidth [ 7] 0.0-60.0 sec 142 MBytes 19.8 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 0.0-60.0 sec 210 MBytes 29.3 Mbits/sec [ ID] Interval Transfer Bandwidth [ 6] 0.0-60.1 sec 170 MBytes 23.8 Mbits/sec [SUM] 0.0-60.1 sec 926 MBytes 129 Mbits/sec
