Hi Guys,I changed the USB Cables, as instucted by
Dalo,and I have ran 7 one hourly speed tests since.All are between 3500-4000 kbs/s.It is like a new PC.
Everything is so much faster.This headache is finally over,thanks to Dalo,and all who helped in trying to figure the problem.The USB Powered adapter was the problem.You are good,
Dalo.
Appreciate the fact that you Guys, just didnt give up, till a solution was found.Many Thanks.
