Hi!

Some more information would be usefull. Which OS are you using on the
desktops, and how are the networks configured (DHCP or static IP).
Would you like the other desktop to be able to access the internet as
well, or would you like the other computer to be preventet from
accessing the internet, and only let the comouters talt to eachother.

Also (when LAN is disabled),

1. I can ping 192.168.2.1 (the router)
2. I can ping 192.168.1.1 (the modem)

When LAN is enabled,
1. I can ping 192.168.2.1 (the router)
2. I cannot ping 192.168.1.1 (the modem)

Thanks.

Then what does it have to do with Linux ? Why don't you ask in a general
TCP/IP group ?

If a default route is defined on the LAN interface, delete it.

Since you do not tell us what you want, it is an impossible question to
answer. Both cannot be "used" to access the web at the same time. But
one can be used to access specific places on the the web while the other
is used to access in general. Look at "routing".

I have 2 desktop computers on my desktop connected to a desktop switch.

One of the computers has a wireless device connected via a USB port. This
wireless
device is used to connect to a Cisco wireless Access Point, via which
intenet traffic passes.

If I disable the LAN on the computer with wireless device, I can access
internet.

I am wondering how to configure the PC so that wireless LAN and LAN can work
together.

Thanks.

I think I understand the open-source people are strenuously defending this
tuft
against "windows" encrouchment; I for one, don't like to see windows
domineering.

I am just curious, if my problem is in the the realm of Linux, isn't the
method of leaving the
entry of default gateway empty the same with Linux ?

Generally I avoid subscribing to many newsgroup; and I think this case
applies to both
windows and Linux. My apology.

I was thinking about this question last night on bed. I figured that when a
network request
is issued, the computer does not know which network to send the request. In
my case,
I supposed the computer direct the request to the desktop switch.

So I thought, why don't I remove the default gateway entry for LAN. There is
entry there
because the gateway was reached via the desktop switch in previous network;
..ie have a
gateway entry on wireless LAN, but leave the gateway entry for LAN empty.

I did that this morning, and the PC now accesses internet via wireless
device, and the LAN
is working normally.

Thanks.
