Internet Connection Drops

[Goodlookinguy]

Alright, this is a bit of a tricky one. I've yet to figure out the exact cause of this problem.

The Internet connection works fine until someone opens up a torrent program and is seeding/leeching. Suddenly everyone, including the person with the program open on their computer, has sudden connection loss and error every 3-10 minute or so. Here are some pictures and other information that will hopefully help.

Company: AT&T
Package: ADSL (3000kB/s Upload and 500kB/s)
Router: http://store.att.com/Catalog/ProductDetails.asp?ProductId=1000-401047-000&CategoryId=catMRG

Here are some pictures, when the error occurs, I'll be sure to snatch a picture of it as well. When the error occurs, on the picture where it says up (several times), the PVC Connection is the first thing on the list to have the error.

Hope someone here knows what this problem is or related to.

Too many connections, overloading your router. Limit the number of connections.

The router is being overloaded eh?

Now when you say limit, do you mean the number of computer connected accessing it or how many ports are being accessed by each user causing an overload?

We have 4-5 people connected at a time, usually, and we have no problems. So I'd like to try and automatically remove the number of users from my previous question. Now, anyone know how to go about finding the maximum amount of consistent connections at once?
