I have a problem about my D-link DI-604 router. I use DI-604 connect to my cable modem and my windows XP. When I browse internet, download stuff, it works perfect, the transfer rate can be up to 300k/s. But when I received files from my ftp server, it is very slow, only 6-8k/s. I redirect the ftp from my router (192.168.0.1) to my computer (192.168.0.100). I don't know why the responds is very slow. I have tried to connect my computer directly to the cable modem, then the ftp speed can go up to 200k/s. When connect back to the router, it goes down again. I have to use the router to connect 4 computers in my house, so don't tell me to remove the router. Any help is very appreciated. Thank you in advance.
