First of all guys, can I just say Thank You to all of you for the help and suggestions.
I had to rush off to work shortly after posting this, so don't think I was ignoring you all, I wasn't
Now, I have tried every suggestion listed above, and so far nothing has worked. I ran the Dr.TCP application from one of the above websites, and did every kind of test available. The tests suggested quite a few tweaks, and I implemented all of them, but still no luck.
All the speed tests were pretty good, more or less my advertised speed, so I can't complain there.
My Rwin number was very high, it was suggested I set it between 5840 and 16060. I did that.
I also set the MTU of my LAN card to 1500 (also suggested)
I enabled the passive ftp thing in Internet Options.
All my cables and phone lines are brand new, inside and outside.
I need to know how to uninstall QOS Packet scheduling (Fuzzy?) And will it wreck anything else if I do?
I am certain that it's just a setting somewhere, and I
will find the damn thing!
Has anyone ever heard about this problem before, corrupted uploads etc?
Thanks again for your input guys, it's really helped even though it's not fixed yet. Keep 'em coming!
