150/10 Connection and Tomato Firmware No GO

    So I love the features of Tomato Firmware, however I recently upgraded my internet to 150 down and 10 up, I was using 45 down and 4 up before which worked fine. After I upgraded the internet I noticed that I can never acheive my full speeds on tomato firmware. With toastmen max I can do on speedtest is about 130Mbps down, on Shibby's about 96Mbps and DD Wrt around 70 Mbps. When I flash back to stock I get a consistent 200Mpbs+ on speedtest. As for Real World speeds on Toastmen using newsgroup I get around 112Mbps consistent, on stock 150Mpbs consistent. Will there ever be a fix for this since I hate stock E4200 firmware. Also tested on A Belkin N600 with tomato same speed issue as the Linksys E4200 v1

    To reach those speed with Tomato you will need a router with a fast CPU, such as the RT-N66U or RT-AC66U. An RT-N16 for instance won't be able to get much higher than 100 Mbits with Tomato (or DD-WRT).

    So what your saying is that even though my e4200 v1 is overclocked to 533mhz(vs RT-N66U 600Mhz) on tomato and using lanspeed test I get almost 477Mpbs transfer speeds it's not enough to keep up with my ISP's speed? but on stock Linksys firmware I able to keep up no problem?

    Which firmware? Try victek last beta fw, he made some tweaks for better throughput

    On stock, the firmware uses a proprietary module called CTF, which bypasses parts of the Linux firewall, and give a huge performance boost. Tomato cannot use the same module because it's incompatible with anything that requires custom firewall rules, such as QoS for example. That's why Broadcom-based routers will always be faster when running the stock firmware rather than any third party replacement.

    If you can overclock it at 533 MHz then I'd say you'll be close to the limit at 150 Mbits. What final throughput you will get depends on which features you have enabled that will introduce processing overhead.

    Lanspeed means nothing, because it's just raw traffic going through the router's switch. That traffic does not get processed like WAN traffic does. LAN traffic doesn't even go through the firewall rules at all.

    Yup, LAN traffic speed will be the same speed between all firmwares, just traffic routed in/out the WAN are different speeds (primarily depending on which settings are configured).

    I'm on 150/10, too. My trusty old RT-N16 would do about 110mbit/s so I upgraded to an RT-N66U.

    I hope by the time of the next speed bump, we'll get something non broadcom-ie that can go beyond 200mbit or I'll have to go back to stock (which is kinda sucky). Cable providers are already talking 500mbit and Fibre providers now do 300/300 for amounts that are not entirely out of whack.
    @RTMerlin: don't the standard build have some form of QoS too that can be configured? And have you ever considered adding some additional config pages to your build (additional tabs perhaps so it still pretty much keeps the default look & feel) ? Running OpenVPN back with script files kinda put me off so I degraded the RT-AC66U (running your mod) to AP duty and using a separate RT-N66U with Tomato as my actual router.

    When you enable QoS on Asuswrt, it will disable CTF (and therefore drop your performance to about the same level as Tomato).

    I did add additional tabs. There are OpenVPN tabs under the VPN section for instance. The Tools menu also adds a Sysinfo page, and additional settings. For example:


    I have reproduced the Tomato interface as much as possible (with Asus's look of course) to make it easier for people to follow Tomato-based tutorials.

    Oh - I must have been hit with blindness. Or the release I'm running is not new enough - as I'm not seeing more than two tabs in the build I'm currently on (270.26). Will try the latest now.

    Umm... what is needed to make the OpenVPN Server Settings, OpenVPN Client Settings, OpenVPN Keys and VPN Status Tabs appear? I only have VPN Server and VPN Details even on the latest build (on an RT-N16)

    @edit: ahh - I think I got it. Seems OpenVPN is only available on the RT-N66U and RC-AC66U. Reading the readme always help :confused:
