Windows – How to Load balance or make two WiFi adapter connections fail-over to the same network

on the windows PC open a command prompt and run the following command:

route PRINT

This will display your routing table on the laptop. Look for the entry that begins with 0.0.0.0 it will appear similar to the following:

Network Destination        Netmask          Gateway       Interface  Metric
          0.0.0.0          0.0.0.0      192.188.0.1   192.168.0.101       20

This should be pointing to the default gateway of your wireless router that is serving the internet connection. Chances are that it is currently pointing to the AD-HOC connection or you may see two entries for 0.0.0.0 with different metrics. The lowest metric is considered the 'best route' to the 0.0.0.0 network (which is your default gateway to reach networks that are not directly connected to your PC i.e. the internet) You can use the command:

route CHANGE 0.0.0.0 MASK 0.0.0.0 192.168.0.1 METRIC X

Replace X with a lower number than both existing 0.0.0.0 entries to make it the preferred path to reach the internet. Also replace 192.168.0.1 with the internal IP address of the router. This will not route your internet traffic from the Xoom to the internet through the gateway, however it will allow you to access both your network and the tablet at the same time.

When using teamview you and the remote machine must connnect to teamviewer's keep alive server, so as default you would need the internet but if you enable 'Accept incoming LAN connections' in Extras->Options, and use the remote computers local IP address you would not need the internet.
