Windows 7 Dual WAN + Load Balancing / Teaming

Configured Manually, with the same network metrics:
http://support.microsoft.com/kb/258487/EN-US/
It suggests a primary gateway, that it's not what I'm aiming for, so I place the same metric, different metrics cause to send all connections to the preferred link.

Also tried a Registry trick:
Quote:
System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters]
Value Name: RandomAdapter
Data Type: REG_DWORD (DWORD Value)
Vale Data: (0 = disabled, 1 = enabled)

Value Name: SingleResponse
Data Type: REG_DWORD (DWORD Value)
Vale Data: (0 = disabled, 1 = enabled)


No luck, it doesn't switch between connections.
Speed tests returns same results as when I have one disabled.
uTorret reports a problem with upload and I don't see any gain.

Some guidance?

  1. #1. A single stream can only go over one connection at a time, so all speed tests will show the max bandwidth of whichever connection it's using.

    #2. You need a NAT/Router that supples translations over 2 or more connections for this to function correctly.

    Google Dual WAN router or "untagle" is nice from what I hear

    as Kewlx25 mentions, you will not be able to have your computer use bother wired and wireless sources at the same time.
    you may also want to look at the peplink balance series of multi-wan routers.
    the entry level model supports two wired wan inputs and is less than $300
  3. Hi, so I have beem scrumming around trying to find a workable solution and devised a workable load balancing vbs code that I wish to pass along and get feedback...

    It is very "chop chop" so please no bashing. Just add some ideas, and I figure this could lead to something worth while!


    The script searches the WMI for the named connections (mine are labeled Wired, and Broadcom NetXtreme 57xx Gigabit Controller - SecuRemote Miniport) Then it finds one of the nics that you want to monitor and change the metric for the balance to work...

    The premise is that if the 'wired' connection exceed 50% of the max load in my case 5.6mbits, it will change the metric to a higher value than the other nic. This will cause all traffic to be routed to the alternate nic. However, what I find, that the existing connections are disconnected and when the mectric is changed all traffic is sent to the lowest metric nic. So this is where my logic ends, and I need someone to figure out how to make the connections of the 'wired' nic persistent and when the metric switch occurs so those connections are not dropped....

    Anyway here it is!

  4. Just get Ubuntu, simple 1 line terminal makes this all possible. Just dual boot like I do :D
