    Hello everyone. Good to be on this forum.

    I was wondering if someone could give me specific numbers for the QoS section as I am really stuck and not sure what to do with it. I already know my maximum bandwidth for inbound and outbound. 6000,29000.

    I want to have the PS3, Wii, and video prioritised. I am sorry if I sound too much like a newbie at this. It would be appreciated if someone could help me with the percentages etc. Thanks guys.

    The link gutsman7 gave is Tomato QOS Bible. If you need to do anything QOS this is required reading. There isn't a catch-all solution, there's a lot of variables and network enviroment specifics.

    I can, however, tell you how I go about doing this, which seems to work alright for me. I grab the Toastman builds (the guy who wrote the QOS Bible) and use those as my QOS base, since he has a bunch of awesome QOS presets entered in. I then enter in additional QOS rules to Toastman's for my setup. There's a bunch of preset percentages, but I end up changing those, to what the pic shows. I'm actually still tweaking things, and I'm sure Toastman himself has spent a long time testing out certain configurations.

    Very much appreciated. Do you mind posting your classification page? Thanks again.

    Most of these rules are ones that come in the Toastman Builds. I may have took some out, and then added some of my own in, such as the Wii (for netflix) and my PAP2T Voip box.

    Thanks for that. My Wii seems to be buffering a lot, do you recommend changing anything?

    I found it much easier to leave QoS turned off, and use the Bandwidth Limiter instead. You can't control individual protocols, but you can set minimum & maximum rates and priority for each device, by MAC or IP. That's all I really need, although at some point I may try to figure out all the classification stuff to get a little finer control. That's all just way too complicated for most of us; this is one of the few areas where DD-WRT really has Tomato beat.

    Two things in the B/W limiter weren't clear to me at first:

    1. DLRate/ULRate are minimum guaranteed speeds for each device; DLCeil/ULCeil are maximums.

    2. If you want to set "Default Class rate/ceiling for unlisted IP's", you have to list devices by IP, not MAC. Any devices listed by MAC will fall under the Defaults, even if you have higher rates or priority set for them. (I haven't thoroughly tested this yet, but that's the way it seems to work.)

    You know, even though I have the Wii prioritized, it still occasionally has issues with needing to buffer. Generally this even happens when there is absolutely nothing else going on in the network. I know however that the QoS is working great everywhere else on the network like with gaming and VoIP. I almost think it has to do with some other issue, like the wireless maybe. My xbox 360 bit the dust recently, but I would bet it wouldn't have issues with a wired connection. Actually the little time I did use netflix, even over a wireless connection the xbox never gave me issues, but I only watched like 2 episodes.

    Interesting, thanks for that Lance. Don't you think tomato is a little too advanced for the average user? Changed to dd-wrt recently and put the Wii's mac address in and it doesn't buffer any more. Just seems like tomato's percentage thing is a little too complicated and needs to be spot on or you have trouble. Just my opinion, what do you think? Thanks.

    I don't know that much about dd-wrt's QoS. I tried it years back and found my self disappointed with it, but I certainly didn't tinker with it as much as I have with tomato. I really couldn't say for sure what is could be, there's potentially a ton of other variables between dd-wrt and tomato. This perhaps is a question more for Toatsman. I would test them both out with zero QoS, and with only the Wii connected to see if they perform similarly, and to rule out anything else but QoS. As far as my buffering issues go, I have a dedicated server that serves up some stuff, that also takes a high priority, and I really don't know when it is and isn't being accessed.

    Oh, one other thing that caught my eye earlier in the post. Your inbound and outbound numbers seem really high. I have a a 1mbit upload, and have set my outbound to 650 (needs to be in kbit/s ). Is your internet really that fast? I think maybe those numbers are higher than what they should be, and that would totally ruin QoS. I think that is my first concern with your streaming issues.

    I have tried just adding the Wii and PS3 with dd-wrt coming out the better. My download is 30 and upload is 8 and I think I read somewhere to use 75 or 80 percent of it.

    QOS takes fine tunning to achive your desired end results. It certaintly takes abit of tinkering to fine tune, never the lest tomato most certaintly is superior to many other open source firmwares. If ddwrt works for you then stik to it.

    The link gutsman7 gave addresses that exact issue, and countless other things. I myself had to be reminded by Toastman in this forum about the inbound and outbound rates. I had been negligent in reading and following the QoS guide, and had to return to it again to get a better grasp. Trying to take shortcuts with this topic will result in less than stellar results, and even educated settings require tweaking. I also feel that tomato is superior to other open source firmwares in Activity, Quality, QoS and true openness. This system will only work as much as you read and really understand how it works. I used DD-WRT for years, and it is a good feature filled firmware. Use what's best for you, but make sure to give them all a fair chance (and do the required reading).

    I actually just talked to my roommate who actually does all the netflix watching over the Wii, I hardly ever use it. I had recently made some changes which I previously shared, and he told me it's been working really good. He said over a whole season of Heroes, it only had to buffer twice. It was much worse than that before, so obviously whatever I did helped a lot, but some tweaking still required :)
