1 computer & 2 network cards

[Patrick Moran]

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.

Since the Internet connection is via the wireless interface then this
should be the one on which you set the default gateway. Don't set a
default gateway on the wired interface too or confusion will reign.

Similarly, when I want to use the internal network, I must disable the
wireless network connection before I can access the internal network.

This shouldn't be affected by having an enabled wireless card unless
your system is confused with multiple default gateways. If setting the
ONE default gateway as described above doesn't resolve your issue then
perhaps if you post your routing table it will provide some clues.

If you're not sure how to do this, boot to a command prompt and type

route print > c:\rprint.txt

This will put a printout of your routing table to a file (rprint.txt)
which you can then paste into your news client and here.

boot to a command prompt and type

I mean "go" to a command prompt not "boot" to. There is no need to
restart.
