Windows 7 with Realtek RTL8102E/RTL8103E frequent connectivity errors

I have 2 PCs connected to my router. One has no issues whatsoever.
The other, carrying windows 7 shows "limited or no connectivity" every 1 or 2 hours.
This is resolved by rebooting.
I think this only happens when using bit-torrent. Not 100% sure though.
I read some posts saying that disabling "Receive Side Scaling" will help.
It's found in :
Local Area Connection>Properties>Configure>Advanced>Receive Side Scaling>Set to ''Disable''.
The problem is that my machine doesn't have "Receive Side Scaling" there ...

Maybe you could run a command to show you the network status both when it is active and when it is not. The differences might help diagnose the situation.

Open a command prompt and type the following:

ipconfig /all > %userprofile%\Desktop\ipconfig.txt

You will need to rename one of the .txt files of course. But you could zip and attach them so we can see what is happening. You could edit them for personal info if you desire, or you could compare them and show us the parts that change.

Make sure and look at the least times for the connection, and you can also compare the two computers as to what they show.

I don't know what is causing the problem but I found a solution to it:
Problem was caused since there was no limit in utorrent to D/L bandwidth. Since I have a very poor Bandwidth it was very often clogged by utorrent. This caused connection loss for good, or until reboot was done (bug ?).
Now connection is running perfectly for 2 days.

I'm afraid the problem is back.
Here is a netstat when problem appears:
