I got D-link DI624 wireless router, and I use the bitcomet to download the most stuff I need. The problem is I normal download speed by using Bitcomet is around 300k, but after I use the router the speed can only reach 80k.
I've tried to open the port for Bitcomet I open the virtual server 6881-6889 & 12242 to 192.168.0.100 and port trigger 6881-6889 & 12242 to 192.168.0.100, but It still doesn't help. I've test when I download reach around 300k and I swich to use Router and It just slow down to around 50-80k and never goes up.

Does anyone know what may cause this, and how to solve this problem.
Please help me out.
Thank you for your time and patience.

I have never used D-link, but have you updated your firmware? Also, some Routers just cannot handle torrents well.

Are you sure your PCs address is always 192.168.0.100? That looks like something assigned by DHCP and it can change at any time.

Setting the trigger ports to such a narrow range is a bad idea unless you are very familiar with the protocol. Don't use the trigger ports at all or if the router insists on them then put in 1-65535
