Im trying to limit the bandwith on a wired computer with a WRT54GS but it not working

    First off here is my specs and scenario:
    -2 Computers: 1 Wired (CompA) and 1 Wireless (CompB)
    -Both computers have windows XP
    -Both computer connected to a Linksys Router WRT54GS ver2 running Firmware Version: v4.71.1, Hyperwrt 2.1b1 + Thibor15c.
    -Router Connected to cable modem (Road Runner ISP)

    So my brother always downloads stuff via torretns and P2P (BitComet mainly), and IT GREATLY slows me down when I'm doing my homework. I want to, either, tell the router to give CompB (mine) full bandwidth and any remaining go to CompA (him and his downloads) OR just block him for downloads only while I'm doing my homework.

    Here is the set up I've tried:
    ---Under the Access Restrictions menu:
    -The Internet Access Status is disabled and I left it untouched.
    -Under Blocked Services I blocked the ports BitComet uses (TCP and UDP)
    -I didn't touch the Websites to block or Website Blocking by keyword

    ----Under the Applications & Gaming menu:
    -On the Port Fowarding subtab, I entered the IP address his computer uses and the port number for his BitComet, and I UNchecked the box.
    -I have nothing on the Port Triggering or Port redirection tabs.
    -UPnP IS enabled, but I'm I disabled the UPnP on the BitComet program itself (so only affecting it BitComet, but this might over ride it I'm not sure, I'm just afraid to turn it off because I might need it for other programs/Sites). Clear port forwards at startup and Send presentation URL are both disabled.
    -Under the QoS Tab I put the HIGHEST priority for CompB MAC address (my wireless). And the following stuff on LOWEST: His CompA MAC address, BitComet Port, Ethernet Port 1 2 3 and 4.

    And that's all I've tried. I still get slowdowns. I was thinking maybe I negated some of the settings since it is not helping me. Any ideas or what else I can do?

    Anything I can do with my router to accomplish what I'm trying to do?
    Thanks for your time.

    I know there has been several strings on this very topic, try searching around abit and you might find something. What comes to mind though is this, yes you have QoS set, the times that you are not using your computer and he has downloads running (24/7 for most torrent users), his machine takes all the bandwidth and leaves none for you. Yes when you come on it may give precedence to your packets going out, but if there is really no room to squeeze your information back in then you are going to feel the slowdown that you do now. What you are mostlikely going to have to do is if you get along, workout the details with him and tell him not to run anything during homework hours (whatever those hours may be). If you dont get along real well then just set up access restrictions blocking his machine or those sites during homework hours and tell him he is going to have to live with it.

    The best and most effective solution is to get your brother to change the configuration of this Bittorrent client and Limit it's bandwidth and number of connections. eg max down to 75Kbps, max up to 25Kbps and number of connections to 30. But that depends on the speed of your Internet connection.

    Because Bittorrent clients can configure their software to use different ports (eg it does not have to be 6881 it can be any high port) you will find it difficult to block and use QOS to limit. Additionally, stopping the port forwarding port will not stop Bittorent upload or download. It will stop him from connecting to peers that also do not have port forwarding configured.

    The endless barrage of small packets from large numbers of connections (peers) will also make limiting bandwidth appear to be ineffective.

    The only real solution you can do without talking and working things out with your brother is to block all outgoing ports except the ones you want, eg keep ports 80,443 for HTTP/HTTP traffic and block everything else. But this will cause other issues.

    We don't get along so if I have to block everything I will.

    So here is what I did:
    Under Access Restrictions:
    -I entered internet policy 1
    -I edit the list of PCs and put down his IP address and MAC address
    -For status I click enabled.
    -For Access I click DENY
    -Everyday 24hrs

    and that caused everything below it to fade away so I can't change.

    Now i save settings and I notice I STILL have slow downs. Somehow he keeps getting connection, how do I block him?

    On the Access Restriction Tab - Internet Access, create a policy
    Select a number, enable it, enter a policy name
    Select the MAC of your brother's PC and save
    Select to Deny
    Select every day and select 24h
    For the port range be sure to disable both UDP and TCP ports 0 - 65535

    Save the settings

    Now he can't access the internet.

    How do I go to the port range?

    if your talking about where I have to edit the list of PCs and than it asked me this:
    "Enter the IP Range of the PCs

    IP Range 01 : 192.168.1. [___] ~ [___]"

    I can only enter 3 digits and I can't enter the 65535

    and if your talking about the blocked services, that is faded out everytime I select Deny
