Problem with Youtube and basic QOS setup

    I would watch a youtube video and while doing that download a different youtube video using youtube downloader. The video I was watching would then freeze on me and NOT continue until the youtubedownloader is almost complete. I don't have QOS turned on and I only have a laptop and a desktop. I am only using the laptop when this happens, desktop off.
    I'm not a gamer and have no VOIP. Pretty much do web browsing, download videos, have sftp on and have a couple of android phones.

    I'm going to try the PolarCloud Tomato FAQ basic QOS recommendations but have a few questions:

    "But in most cases, simply entering 90% of your maximum upload speed in QOS/Basic, putting your VOIP device's (if you use one) MAC address on "Highest" and on the top of the classification list, and leaving everything else as-is...."

    My download is 15.5 Mbps and upload is 5.5 Mbps.
    My outbound limit: 5.5 Mbps x 1024 kbps= 5632 x 90% = 5069. So this is what I enter in the box.
    Nothing mentioned about inbound limit. Defaults are 230kbps OUT and 1000kbps IN when I turn on QOS.
    Do I leave it at 1000 kbps or do I take 90% of 15.5 Mbps?

    I’ve added the Bulk Traffic entry(#5) for the classifications which is the 5th entry on the page.
    There are up and down arrow to the right of each entry. Do I rearrange it to show Highest on the top and lowest on the bottom?
    As it is it shows: High, low, highest, lowest lowest.
    Do I change it to Highest, high, low, lowest lowest?
    Do I have to use any iptable stuff for my simple setup?

    I have the Asus RT-N16.

    Not sure why you are messing with QOS in your context.

    So I don't have to mess with QOS for my setup is what your saying?

    I wouldn't.

    So the youtube download is starving out the youtube video you're watching? Do you know what protocols are in use? I believe that QOS can be used to lower the priority of one type of protocol vs another but you need to figure out what they are first. My first thought would have been they're the same protocol but if that was the case one shouldn't pause the other.

    Do I do that by netstat? Can I distinguish the PID of me watching youtube compared to a PID of the download?

    I've managed to classify Youtube videos etc reasonably well. Youtube uses several protocols, I believe. HTTP video and Flash L7 filters are necessary to do a good job on most of the material.

    You can pick out examples of rules from the screenshots at the location at the bottom of the article. Those classified as "Media" may also be involved in streaming content and link setup.

    You know I'm not 100% sure but you read my mind as that's how I thought to start looking at it. If you run a software firewall like Symantec then you might find some info in the logs. And you can consider a more sophisticated tool like wireshark if needed.

    But your setting or context is not the same as tomato's....

    Well I decided to check my hardware stuff first to see if that could be causing my frustration. Defragged drive, created more free space, scanned for virus, removed some networking software, wireless driver up to date. Still no luck. Up until I noticed my wireless was set to Auto. Changed it N and all the floodgates have been opened. Now I can view, at least I tried, up to 5 simultaneous youtube videos on different windows while simultaneously downloading a video with yourtubedownloader. All my network devices are N. Funny how 1 setting can make it or break it. Thanks for all your help.

    On the other hand it's not a question of filtering youtube traffic; Setting proper QoS rules for p2p etc and the outgoing traffic to 80% or less is something you may want to double-check before proceeding.
