Thank you very much and enlightening me about not to jump to the conclusion.
As I told I use Bitcomet 1.1.13 I configured a port and green WAN is appering event I restart ny modem who changes IP. Because I change everytime the port with the new IP (It's a Cisco Linksys WAG54GP2 router modem and the IPs begin from 192.168.1.64)
But When I use Bitcomet and open a http page or outlook or another operation such as starting MSN I got some problems of connection and connection slows down dramatically.
But with Bittorent 4.4.1 or utorrent 1.8.3 the same connections are not affected it goes very well.
In fact except this I was very glad using bitcomet which ise very complete for such P2P connections.
If there is a way for adjusting this I'll be happy to use Bitcomet as I was using before.
The configuration:
I have the router modem WAG54GP2 Linksys, a memory 2GB kingston 800DDR2 SDRAM, Gigabyte mainboard, AMD Athlon 64 X2 2600 FSB (no Overclock)
I have configured a port in windows firewall for TCP and UDP and in the router modem too. My bandwidth, because of the distance form the source, is 1MBS/256kbs
If there will be an advise for keeping speed of my connection for other connections (such as WEB, outlook) while I was uploading/downloading files, in the same speed of bittorrent or utorrent, I'll keep to use Bitcomet cause I like it.
PS:In my 1st post I did not ask any help for utorrent or bittorrent I asked if there is a compatibility between those torrents.
