Default 1 computer & 2 network cards

I have 1 computer which has a wireless card for internet
connection and a wired ethernet card for connection to internal
network resources on a different netowrk. The former is on IP
range 192.168.2.x and the latter is on 192.168.1.x
The problem I have is that I cannot connect to the internet when
both connections are 'enabled' and working. To connect to the
internet I must disable the lan adapter for the wired internal
network. Similarly, when I want to use the internal network, I
must disable the wireless network connection before I can access
the internal network. I do not get any error messages, other than
after a period of trying to connect, the attempt just seems to
'time out' It seems to me that the 2 networks are getting confused
with one another. I have tried bridging the networks but this did
not work. Any suggestions are much appreciated.


Given a wireless and wired network connection to a computer, the
default for Windows is to prefer the wired connection. You can change
the preference by changing the Metric assigned to each NIC. In your
network control panel, right-click on your wired connection and select
"Properties". Then in the window, scroll down to the bottom and
double-click on "Internet Protocol TCP/IP". Then click on the
"Advanced" button. Then, at the bottom, there's a box that's probably
already checked labeled "Automatic Metric". Uncheck this box and enter
a metric (number) into the "Interface Metric" box. For your Wired
connection, enter "10" and then "OK" to close out all windows. Repeat
the process for your wireless connection except enter the metric "5".
(the lower metric gets the higher priority).

This should direct your default gateway through your wireless card
instead of your wired card if both connections are active.

HTH,
John
