Router: Asus RT-N12 C1 (identified as B1 on Tomato web admin page) Tomato firmware mod/version: Shibby mod v.99 (tomato-K26-1.28.RT-N5x-MIPSR2-099-Max) No other traffic is present during testing. QoS is disabled. With WMM: Without WMM: Is this intended behaviour? I know that without WMM I would be limited to G speeds. But enabling it (and thus enabling N speeds) seems to have a counter-intuitive impact on my download speed. UPDATE: Flashed Shibby v.100, cleared NVRAM, and WMM is still giving me the same impact on download throughput.
