    Hi all,

    I have ASUS RT-16N router.
    I had some time last weekend so I made some tests with stock and Tomato firmware. I focused on wifi transfer speeds, because I need stable and fast connection.

    I used latest firmware versions:
    ASUS stock firmware version
    Tomato Toastman 1.28.7497.1 VPN NOCAT

    I used same channel, channel width, same place, same hardware and antenas orientation.

    After 10tests with 100MB files I got these average results:

    Tomato firmware: download speed 19,52Mbps; upload speed 21,39Mbps
    Asus stock firmware: download speed 26,93Mbps; upload speed 29,03Mbps

    OK, is ASUS firmware really so bad? Because on ASUS firmware I have better speed on wifi than on Toastman... stability is not bad... I think the latest version is pretty stable...

    I have been using TOMATO firmware since August 2011, I like it because it is stable and developement is very fast.

    I dont know why the transfer speed are co different. I tried change channel and channel width on tomato firmware, but the results were same.

    Sorry for my English, it is not my native language.

    Your Tomato speed is about what you used to be able to get with wireless-g LAN to WLAN transfers. bit faster if both router and client supported SpeedBooster.

    What mode is your wireless connecting in and where are you downloading from internet or local lan?

    I downloaded from PC connected over lan to router. Same file 10 times. I think the latest stock asus firmware must have some improvement in performance... because when I bought router in August and I tried the wifi with stock firmware, the speed was terrible compare to tomato which I installed two days after...

    There are a series of features that the stock Asus firmware might enable by default which TomatoUSB doesn't. One such example is Speedbooster (called Afterburner and many other things) and a whole multitude of other features.

    The only way one would really be able to diagnose and determine the source of the difference would be to do actual packet captures on the LAN segment (e.g. on the machine you're transferring the file from? Or to? DIRECTION MATTERS! :) ) using Wireshark or something similar, and have someone do actual analysis of it. I'm familiar enough with Wireshark to do such an analysis, but I really don't have the time to step you through how to properly use Wireshark, write a pcap filter that's specific the traffic you're testing, etc... I'm talking about IP/TCP packet captures by the way, not layer-1 and layer-2 framing (wireless) captures -- I can't analyse those (and doing so is difficult given that promiscuous mode is often disabled in vendors' drivers for wireless chipsets).

    But here's an easier test that would rule out the need to do IP/TCP packet captures: do the exact same test on both firmwares but using LAN (wired) only. That would at least narrow down if the issue is specific to Wifi or not.

    OK, with frame burst I can get improvement - about 2Mbps
    Asus stock firmware must have something else, I need next 5Mbps :)))

    Keep testing
