Thanks Q and Kent...
I tried the Winsock Fix and it works perfectly for about 5 mintues and then
back to the same old sluggish intermittent internet. I had a problem with a
Trojan or a worm a long while back stopping up my bandwidth, but I got rid of
it and everything has been fine for months now.
It is starting to act like it's back, but all scans fail to detect anything.
Plus I got rid of it so I doubt it could just spontaneously reappear. It's
not the cable because I unplugged the other computers and it still does the
same thing. It's an issue with the computer itself.
Haven't tried the changing from Dynamic to Static IP, but I'll give it a
try. I still think it's something else though because this is the same setup
I've had for a year now and except for the one problem I had a few months
ago, the dynamic IP has worked fine. I will try the static to be on the safe
side.
Thanks again guys!
