Okay... I'm on a cable modem where I used to get up to 300kbps downloads usually, to like 10kbps...
I don't use a router/network, proxy server... I'm a single computer connected on an ethernet modem to my ISP...
I tried releasing more ports since I have xp sp2, but that didn't work.
Some connection scans on the web detected that alot of packets are being lost and some ports cannot be reached by them - connections get lost about 10 steps before they reach my computer. I haven't run this test before my comp slowed down, so I don't know if this is the reason.
Only thing I can think of is someone is blocking traffic to my computer or my ISP is having problems... What else could be wrong?
