I have two different Internet connections in my computer, each in a different network card. One is a 30 mb/s optical fiber link and the other is a 20 mb/s cable link. I would like to combine both and get a 50 mb/s link, or, at least, have them working in tandem in a load balancing mode. I've read a post in another forum stating that Window 7 Ultimate 64-bit (which is the one I use) is capable of automatically use load balancing when there is more than one Internet connection available. I tested it and it does not appear to be the case. I configured both connections to be part of the Home Network. They were joined, but only the faster one worked at a time. I, then, configured one of them to be a Work Network, but to no avail. I used a torrent client for testing, because it would be able to use both connections simultaneously. But, always, only the faster connection was working at a given time. If the faster connection was disabled, the slower one would take over automatically. But I was never able to see any downloading speed improvement during my tests. Is it true that Windows 7 will do load balancing automatically when the computer has two active Internet connections? If so, are they supposed to be in the same network or in different ones? Is there any configuration or registry change which must be done? Thanks in advance for your help.Eduardo Quintana .NET Developer

what you are asking about is called Channel bonding, and as far as I know the framing rate must be same for both connections for it to work.Load balancing in most cases is not bonding channels it is using the least used / or fastest connection, like when you access some websites which are hosted on a server farm.or using one connection for web surfing and one connection for upload..things like that.I do not think that win 7 would do channel bonding without help. You can pickup a daul port wan router which will do this (200.00 ~ 300.00 USD)

What you're wanting is adapter teaming, generally done with servers http://www.microsoft.com/windowsserver2003/technologies/storage/mpio/default.mspxor the use of a dual WAN router.additional information for you http://www.intel.com/support/network/sb/cs-009747.htmhttp://www.microsoft.com/windows/compatibility/windows-7/en-us/Details.aspx?type=Hardware&p=Intel%20PRO%2F1000%20MT%20Dual%20Port%20Server%20Ethernet%20Adapter&v=Intel&uid=PWLA8492MT&pf=0&pi=8&c=Networking&sc=Ethernet%20Adapters&os=32-bit Network Load Balancing, a clustering technology included in the Microsoft Windows 2000 Advanced Server and Datacenter Server operating systems, enhances the scalability and availability of mission-critical, TCP/IP-based services, such as Web, Terminal Services, virtual private networking, and streaming media servers.

I would suggest you to follow these steps. 1. Open Network Connections by clicking the Start button, and then clicking Control Panel. In the search box, type adapter, and then, under Network and Sharing Center, click View network connections. 2. Right-click the connection that you want to change, and then click Properties. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. 3. Click the Networking tab. Under This connection uses the following items, click Internet Protocol Version 4 (TCP/IPv4) and then click Properties. 4. click Advanced 5. And Uncheck Automatic metric and assign value as 1 for faster connection. 6. Click Ok. Hope this information helped!

The solution to your problem is RandomAdapter registry key, which will enable Windows built in feature of randomly using multiple internet connections. http://technet.microsoft.com/en-us/library/cc784947%28WS.10%29.aspx I think you also need to add ConnectOnRequestedInterfaceOnly registry key. http://technet.microsoft.com/en-us/library/cc781782%28WS.10%29.aspx I added those two keys and rebooted, now my bandwith has significantly improved when I download stuff.
