True, but it wasn't doing that. It was using the lower bandwidth connection.
For some reason the Interface metric was greyed out for the lower bandwidth NIC. I uninstalled it and re-installed it and can now set a higher metric on the USB NIC. This has resolved the issue.

The slower network has better ping times by a couple of milliseconds, however, it is less than half the bandwidth, and not the network that has first priority in the network bindings.... From: Bob Fronk [mailto:[email protected]] Sent: Tuesday, June 14, 2011 9:03 AM To: NT System Admin Issues Subject: Windows 7 - Multiple NIC binding order Windows 7 Enterprise 64bit with two 1GB NICs. (NIC 1 is internal. NIC 2 is USB dongle) Each NIC is connected to a different subnet, LAN 1 = Domain LAN. LAN 2 = Local Test network. LAN1 is the domain LAN and has a 45mbps Internet connection. LAN2 is a test network and is connected has a 20mbps Internet connection. LAN1 is 192.168.x.x. LAN2 is 10.10.x.x. Both are DHCP. Both are 1Gbit networks. I have set the binding order for network services to use NIC1(LAN 1) first. The wireless (not connected) second. NIC2 (LAN 2) third. Windows has designated LAN 1 as "Domain Network" and LAN 2 as "Work network". However, at each log on, the OS is using NIC2 for external traffic (Such as WEB, Outlook connection, etc.). I can still connect to the domain LAN, however it is not primary. I have to unplug the network cable for the OS to switch to LAN1. If I plug the cable back in, the OS will switch back to NIC2 at various intervals. I use the test network for some VMs I run on my PC for testing purposes. I need external access for these VMs, but I do not want them on the domain network. This was working fine for me until my old 100mbps USB NIC experienced a "drop and break it" incident. The new USB NIC is 1Gbit, so I am guessing that Windows sees this as a "better or faster" network and somehow makes it priority over the Domain network. Beyond setting the binding order (which I have done), does anyone know another way to force Windows to use "think" LAN1 is the best priority network?
