[DD-WRT/Tomato]使用Afterburner提升無線傳輸速度
Afterburner是Broadcom特有的無線傳輸技術, 可提升無線傳輸速度到125Mbps. 若依Oleg所回覆的這篇, Afterburner(125Mbps): 35Mbps; 802.11g(54Mbps): 27-28Mbps.
當然, PC端也要使用Broadcom無線網路卡(例如: 華碩WL-138g, WL-169gE)
雖然DD-WRT, Tomato都有提供Afterburner選項, 但以wl命令測試, 並非所有Broadcom的Router都具備此功能.
Belkin F5D7230-4

換WL-500W的WL-121W R1.03
