My internet connection slows (or stops) when uTorrent is running

[0verture1001]

I followed the guide in this thread here, even tried Switeck's conservative settings. None of it has improved my internet performance while uTorrent is running.

Basically, the moment I run uTorrent, my internet either slows to a crawl or becomes unresponsive entirely. Web pages timeout, I can't connect to remote servers, etc.

This problem only cropped up after I switched from AT&T U-Verse to Comcast. AT&T provides a Residential Gateway for U-Verse subscribers, and even though the speed of the connection was slower, I could function normally whilst online with uTorrent in the background. Now that I have Comcast, I have my own modem and my own router and things are not working out so well.

Cable Modem: Motorola SBG901

Router: NETGEAR WNR3500L (latest firmware)

Comcast XFINITY Internet

I recently changed my port, and it is opened (forwarded)

Windows 7 x64 Professional (up to date)

ESET NOD32 4.2.71.2 - I have tried disabling my antivirus to see if that helped and it didn't.

I don't have much else running in the background in terms of services/processes. I run a fairly clean PC.

Any help?

Missing your current uTorrent settings (yes they are important)

While these settings might look too aggressive, they were not causing any problems for my connection while I had AT&T U-Verse and the RG unit they provided.

Also keep in mind that I have tried Switeck's conservative settings, which includes lowering max. global connections, connected peers per torrent, and other advanced settings.
