Re: Giving priority to MJ traffic (QoS, Tomato Firmware)
I'm trying to set up QoS on my ASUS WL-520GU router. Unfortunately I can't get good results no matter what I do...
My actual down- and uplink speeds are 6800/490 kbps. But as soon as I enable QoS on Tomato 1.21ND, my speeds are capped at 3900/380 kbps - no matter what the other settings are! The loss of 40%+ of downlink speed seems too much. What could I be doing wrong??
Setting aside the question of whether or not using QoS will improve my VoIP quality while using torrents or HTTP downloads, how can I enable QoS in Tomato on my router without limiting my download speed permanently at ~60%?
Does anyone get better results with the same router? |

For general Tomato questions, it would be better to go here:

Post your actual QoS basic settings and classifications. My guess is you have something wrong with your QoS settings.

One thought. Are you using a cable tier with "speed boost?" You didn't say how you're measuring your speed. But, if your service has a variable download speed (an initial burst), then you'll lose the benefit of this when setting the inbound speed in Tomato's QoS.
This seems to be a shortcoming of QoS. You have to specify the lowest speed you normally encounter. You can never take advantage of higher speeds. (If you specify a higher speed in Tomato, it could cause congestion, reducing the benefits of QoS.).

| Thanks amigo_boy! I'm checking the linksysinfo forum now, and will ask there if I don't find the answer...
And no, my cable provider does not use "speed boost" - my speed is stable at 6800/490 kbps. That's what all speed tests show (speedtest.net, or speakeasy.net), and that's what the torrents reach if I unleash them (well, at least download - torrents never reach my upload limit for some reason). What's interesting is that when QoS is activated on Tomato, the download speed is always capped at 3900 - no matter what downlink speed I specify in the settings. I can set it to 1, 4000, 7000 or 100000 - it's still capped at 3900 as long as QoS is enabled  ... |

I've never cleared NVRAM on my router. I don't know if there's any risk of bricking your router.
If I were having your trouble I would go into Tomato's Administration->Configuration->Restore Default Configuration-> Erase all data in NVRAM memory.
Maybe power off/on after that's complete. Then reconfigure Tomato, but be sure not to change any inbound settings on the "basic settings" page except the max inbound limit. (I.e., leave everything below the inbound limit set to "none"). And, don't change anything in the "classifications" page.
If that doesn't work, you should post to that Tomato forum I mentioned earlier.

| I am on a cable connection with powerboost (8/2, boosts to about 20/4). There is a trade-off between setting QOS and putting MJ traffic as the first priority and not setting QOS and achieving my full Internet speed. I chose the latter. My connection is fast enough that MJ shouldn't be interrupted at all unless I happen to be torrenting or something at the time. |

I wasn't impressed when I tried it (compared to ordinary QoS with Tomato). But, my speed is 1.5/.5. Maybe it would do better on a faster connection than no QoS (or limiting your powerboost using ordinary QoS with fixed, slower speeds representing your average speed).

Mark I am not crazy about DD-WRT -- the developer is trying to commercialize it and make money on the back of GPL'ed code. There's nothing wrong with that IF the GPL license is adhered to. But, as many on various forums have pointed out, he seems to want to control where DD-WRT can be used (i.e., he only wants it used at home, which might violate the GPL). |

There is now an unofficial (modded) version of Tomato 1.22 with TCP Vegas. Just announced here:

"TCP Vegas (TCP congestion control) added (enable in QOS:Settings), thanks to Rodney H. (see his writeup here for more information)."
