    On my old router, whenever I used utorrent, my internet one my wireless laptop would bottom out. It would either go really slow or it wouldn't even load pages. To fix it, I had to restart my laptop, then it would work just fine.

    People told me this was one advantage of going to tomato, there was a workaround for this. Can anyone help me out?

    I've never had any problems with uTorrent running on my Tomato router. Never did anything special to either uTorrent or Tomato settings, it just worked right out of the box with default Tomato QOS settings.

    Man it's a weird problem I have no idea what's going on.

    My old laptop worked fine (Vista Home Prem), and then I got a new one, which also runs Vista Home Prem, and utorrent is giving me a real tough time.

    I haven't tried port forwarding, could that help?
    I'm actually not sure how to set it up, so any help would be appreciated (I used portforward.com on my old router, and they walk you through all the steps, including setting up a static ip).

    Man, I just use Tomato's static DHCP on all my network devices, turn on UPNP in Tomato (might be on by default?), turn on Tomato's QOS using default settings (adding in a couple for Xbox Live prioritizations) and use the default uTorrent settings on my Windows XP machine. My Macs run Transmission for bit-torrenting, and they have no problems with default settings, either.

    When you say Tomato's static DHCP, are you talking about going to Basic-->Network-->Type? Under type you choose DHCP or static?
    Upnp is on be default on tomato.

    Should I also be turning on upnp on utorrent? (it is off by default)

    Paparay, turn on QoS first. I believe it's off by default. Port forwarding will help your torrent download speeds, but it shouldn't slow down browsing.

    If you decide to use UPnP, it will need to be on in your torrent client and on the router. I decided to manually set up port forwarding with a port that I randomly choose because of torrent speed benefits I read about.

    But definitely make sure QoS is enabled. It's a lifesaver.

    I enabled QoS, and made sure tomato and utorrent were running upnp.
    My download speeds went up drastically! Thanks.

    However, my browsing still doesn't work (tried on IE and FF). I don't think the issue is utorrent taking up all my bandwith, since I can still use the internet on other computer that are on the same network.

    Something just isn't right for some reason.

    No, I'm referring to static DHCP for Tomato's DHCP server, not what type of internet connection the router uses from your ISP (DHCP, static, PPoE, etc.). Go to Basic-->Static DHCP.

    Yes, I would use UPnP in uTorrent. Enable UPnP and NAT-PMP in uTorrent's connection settings.

    Oh, so the internet browsing only breaks on the computer that is currently downloading a torrent through uTorrent? Yeah, that's not a problem with the router/Tomato, that's a problem with that device. It's probably Windows'/Vista's TCP connection limit or something.

    Exactly. Is there any way to work around it? For some reason my older Vista laptop didn't have this problem.

    I've seen something similar. When torrents are downloading fast, on that particular PC web browsing is noticeably slower. With QoS was off I couldn't browse at all. Other PCs don't have a problem browsing at all.

    I think perhaps it's an issue with the number of connections that torrents keep open, but I've not investigated it. And since I'm about to configure my Buffalo NAS to handle torrents I'm hoping my problem will go away.

    I'm glad your torrent speeds have gotten better, and I hope someone else has an idea for your browsing problem. I can't offer much other than my sympathy.

    I was reading some more about it.
    Some people think the half connections have a problem Vista. They apparently limited it because it can help stop virus's from spreading.


    That site offers some sort of patch, but I went through the first 10 or so comments, and already a couple of people were complaining of the Blue Screen Of Death...so I don't think I want to try that way.

    Hopefully someone has gone through this before!

    I've changed the half-open connections setting in Windows XP and it caused me no problems. (My slightly-sluggish web browsing was an issue before I made the change. To be fair, I can still browse when downloading torrents but I can tell there's a torrent going in the background.)

    I changed the max half connection thing in utorrent, but it won't work.

    One way--although I haven't tried it...is to download some Vista patch and have it fix something.

    I'm a little hesitant to download it without having some people letting me know it's totally safe...some comments say it cased the BSOD! but lots of people say exaggerated things in comments.

    Yes, you most likely need to increase the number of half-open TCP connections in Windows. I don't see how setting that in uTorrent would even do anything to Windows' TCP/IP stack.

    You MUST use the patch or you will have no cure for what ails you. Until you do you are effectively used a crippled operating system.

    Get the patch from this site:


    The default of the patch is to set 50 connections as a limit - this will not be enough. Select CHANGE and then enter 500. Then apply the patch and your troubles will probably disappear.
