netstat shows too many established connections in windows
I have an Internet service by ADSL, the problem is that my download speed has decreased dramatically in the order of 60 or 70% down. One friend recommend me to put netstat -an on a terminal window and I got the following results:
The problem is that my actual IP is:
One quick question appears here, is it not suppose that the Local Address:
xxx.168.1.34 should match my ip xxx.43.236.168?
In any case, I was blaming my ISP because of the decrease of my internet speed, but my technician friend told me that maybe I have some trojans that are making these connections.
The weird thing is that when I boot my PC with Linux I only got two ESTABLISHED connections, and the internet speed has the same values as its windows counterpart.
Update info: I have applied netstat -an to see the established connections under Linux (I have both operating systems on my PC) and these are the results:
In both cases I am accessing thru the Internet using a wired connection, the wireless is deactivated.
What could it be going wrong? Should I change of ISP? Help, please

I have a similar problem to yours. I just called the customer service of my ISP and they ordered me to do netstat -n -o, then I found too many ESTABLISHED connections. The agent said that this is the problem of my weak bandwidth and I must have my PC clean from viruses and malwares.
I run Tcpview software and as you see the result in the image. Here is many ESTABLISHED connections but it belongs to some apps running on windows or some system processes. So, I didn't think that it is the cause of the problem. Now, my internet speed is good although there are still too many established connections on my PC.
I just wanted to share my experience and with it will help.
