When I said it terminated all connections, I mean to the box, not to the program. It's effecting all NIC traffic including my Remote Desktop connection which it promptly terminates.
I doubt this is something I can fix. Or if I fix it, it'll just be by accident. This is just a guess but, I think something in your windows is running out of RAM so, there's no room for additional network packets. I think you're going to find that it's specific to this machine or to old security software. Newsbin sets large read buffers to improve speed. my guess is, when you enable the limiter, these buffers fill up and there's no room left for additional packets. Might be a function of the NIC or windows running low on RAM, I don't really know.
You understand that MANY people use the BW limiter and don't have this problem right? Even the original poster is just complaining about the speed, not that it's killing his PC.
1 - First thing I'd do is cut the connections down to 1 or 2. See what happens.
2 - Next thing is tell Newsbin to use smaller net buffers.
HKEY_CURRENT_USER\Software\DJI Interprises\Newsbin50\Settings
RecieveBuffer
I'd set this to 8192 decimal (2000 hex).
This value won't be there. You'll have to add it.
Again see what happens.
