1. There is a Read This Before Posting announcement on top of this section; read it and answer all the questions.

2. What color is your status light now?

3. What are your connection settings in BitComet?

4. What does the Peers tab show you? (post a screenshot)

5. What does the Statistics tab tell you now?

Opening a udp port (or not) is not going to affect your download speed one way or another. It will allow you to connect to the DHT network (uses only UDP), which may get you some more peers than you'd otherwise have. Once you have those peers, though, they're treated exactly the same. You need to be looking elsewhere.

but is it ok to open the same port number??? What i did is opened one port using tcp and i used another description

and i opened the same port number using udt???

It is not literally the same port. It is just the same port number.

But TCP and UDP protocols use separate port address spaces, even though they are both from 0-65535. Therefore you can use the same port number if you are using different protocols (UDP or TCP). Because a socket is formed by IP address and protocol port number.

And yes, not only is it ok, it is required. BC uses the same UDP port number for its DHT connections as its TCP port number for bittorrent connections.
