i am using a router and i done all the portforwarding. however, no matter i use bitcomet, azureus, utorrent and emule, all download speed is dead(1-10kbps) for me but my upload speed still very fast(around 40kps). before the earthquake my download speed has no problem at all. Beside, my normal http download still remain as usual.

I hard try many ways such as do protocol or disable firewall but nothing is work for me. i really no idea of what had happen. is there any suggestion for me? no p2p download is killin me.

between my router i using is zyxel prestigo 600 series.
