I can download, almost normally, just few results and a bit harder to connect.
But only some 2-5 uploads a day are succesful. The rest time out.

All I found around are router/firewall-related problems. But I don't use any .
And WinMx setup detects the TCP and UDP ports as working.
I was told that is becoming a somewhat usual problem and is related to compatibility problems between WinMx V3.5 and V 3.3.
Could that be the reason?

99% of my uploads timeout (I guess my downloads are afected too)
I have tried with primary and secondary conecctions, opening different ports or not using them at all.
Also reinstalled all the network protocols (Win ME)
I don't have a router. My ISP is cablevision/optimum.
Thanks for any idea.
