When I use uTorrent to download and it reaches the highest bandwidth (50 Mbps), it drops the connection for a few minute, and then reconnects. As I often use my Internet connection it is quite annoying when suddenly there is no connection.

The firmware is the latest (07.23), I am connected via Ethernet cable.

I set the QoS to always provide 50 Mbps but no luck: http://s16.postimg.org/4ur7ziqud/qos.jpg

Here us the speed graph: http://s14.postimg.org/jptsaqk7l/tplink_speed_issue.jpg

What should I do?

It dropped the connection 4 times in 20 minutes. What should I set? Why does it drop the connection? –  Nestor Aug 30 '13 at 20:58
    
My connection is 60/6 Mbits/s. When my download speed reaches 1.5 MB/s, I cannot reach the router and speedtest.net shows, I have a 3.5/2 Mbit/s. What is it? –  Nestor Sep 29 '13 at 19:08

Sadly, it is a common behavior of the routers all around the world. The torrent uses so many connections that the router's routing table is filled with addresses so quickly that it overflows and drops the connection to prevent the incoming of more addresses to route. It should be more fault-tolerant, but when these types of routers were designed, they didn't think of such a scenario.

The only solution is to reduce the available connection in your torrent client.
