New Router, new upload speed problems.

My previous router was having some serious issues, propping packets and riciulous pings, so I got a new one, a TP-Link TL-WR841N. I've been using utorrent for years and had gotten the thing to a good place, where I could upload and download at solid rates for my Inernet connection, but as soon as I installed the new router, things didn't work so well. Now, my downloading capabilities seem fine, several hundred kb/s, which is what I've always had, but it just doesn't even try to upload anymore. when things are in seeding mode it only seems to connect to a handful of peers  at a time, even if there are plenty available, and only seeds at a very low speed, like under 1kb/s. Torrents of a type that used to only take me a couple hours or less to 1:1 now just sit there the days without balancing. My utorrent settings haven't changed, so it has to have somethign to do with how the router works, but I'm wondering what I need to change to make it work like it used to. One theory I had was that since the new router seems faster in some aspects, maybe it trips some red flag at Comcast that the old router wasn't allowing, and so Comcast is throttling my UL speeds? Or is it some setting in UTorrent that worked fine with my old router but would get tripped up with the new one? I'm just hoping someone has experienced a similar issue and figured out a way around it.

So just an update, I installed the newst verion of Utorrent on my tablet, and when I downloaded something on that, my seed and peer connections were as I would expect, and it easilly hit a 1:1 ratio in short order. My main computer still refuses to seed anything. A couple of peers will pop up, and vanish before they can get away with anything, on files that should have a healthy back and forth. I compared settings in the preferences, and changed all the ones that were different to be like the tablet's, but that had no effect. It downloads perfectly fine and perfectly fast, but barely trickles out the uploads because it refuses to stay connected to a peer for more than a few seconds at a time. Right now I'm looking at five actively seeding files with two connections between them, each transfering less than 1kb/s. What's going on here? How do I fix it?
