    Hello.

    For a while i've realised that our Internet speed is maxed out at around 280mbit/s, after calling the Provider they said we should connect the PC directly to the Cable Modem (TC7230). Did so and made a Speedtest.

    Everything works fine!


    So using the Advanced Tomato firmware "tomato-R6400-AT-ARM-3.4-140-AIO-128K" i had huge problems with Speed.

    Maximum 300mbits, Average 285mbits.... Something clearly is wrong here... right? (Oh.. and yeas, i did a NVRAM reset during these Tests, so this result here is the best i could get out of various test over multiple days!)


    To get back to Stock Firmware i've flashed "dd-wrt.v24-K3_AC_ARM_STD_128K" and of course made a Speedtest with this Firmware......

    You can see the Maximum going up to 300mbits, but the average stuck on 120... uhgs!


    So yeah, i've finally flashed back Stock Firmware, "R6400-V1.0.1.22_1.0.17" to be exact.

    Now look at this! it doesn't look as sweet as on the PC, but it's a Solid 387mbits Average with 497mbits Peak.



    So yes, Stock Firmware is WAY faster than DD-wrt or Tomato, so there has to be something wrong....
    Is it a configuration error? or something in the Firmware?

    Anyone can help me out here?

    Advanced -> Miscellaneous -> CTF
    Have you tried enabling this?

    I did, and it did increase the speed by quite a bit!

    Why is this not activated as standard?



    P.S
    [​IMG]

    This is with Tomato and CFT activated and Overclocked to 1000Mhz


    Thanks for all the Help :) this small setting solved it all.

    It's not enabled by default, probably because it's incompatible with a few notable tomato features, like; qos, bandwidth monitor, IP Traffic, Bandwidth limiter etc.
