Mixed wireless and wired (Ethernet) networks

Hello,

I have a PC running WinXP Home which has two network adapters
installed: wireless 802.11g and Ethernet. The wireless works
perfectly. However as soon as I plug in the Ethernet cable, the
internet connection goes down. The ethernet connection has a fixed IP
address of 172.16.1.203 and a subnet mask of 255.255.0.0 and no
default gateway.

How can I get both of these network adapters to work together. I have
made sure that the preferred network order is: 1) Wireless 2)
Ethernet. I have also tried putting in the 172.16.1.203 address in
the alternate configuration for the Ethernet connection.

Any other help would be appreciated.

Thanks
Mike

What's on the other end of the Ethernet cable? How do you know it's working?

How did you configure the "preferred network order"? Did you change the
interface metrics? If so, what values did you use?

In the properties for each adapter under TCP/IP properties, click on
the Advanced button. You will see a box labeled "Automatic Metric"
that is probably checked. With this box checked, a wired connection
will take precedence over a wireless connection. Uncheck this box and
put a number in the "interface metric" box. Lower numbers are
preferred (higher priority) over higher numbers (lower priority). Do
this for each network interface.

Hi
Having two Network card on a computer create a Psychological problem among
many End Users that can not let go that there is piece of hardware that is
useless under most scenarios.
You have to explain what is that you intend to do when you say working
together.
In most cases there is No working together when using regular client OS. You
let them work one of the time with Metrics, or switch Off the One that you
do not use. ( http://www.ezlan.net/metrics.html ).

I tried this and it does offer help.

I tried entering 10 for the wireless and 20 for the wired connection.
However now
the wireless works but the wired doesnt.

Is there something else that can be done to get the two networks to
work at the
same time?

Thanks
Mike

I posted your next step in microsoft.public.windowsxp.general.
In general, you should cross-post instead of multi-post when you can't
decide where to post.

No. You can't have wired and wireless connections active on the same
computer at the same time.

Of course you can. You just have to have the routing tables set
correctly.

That depends on the ip address of the wireless subnet which remains
unknown at this time (at least as far as my newsreader goes). If the
wireless is on a different subnet to the wired there shouldn't be an
issue in the first place.

Doh! You're right, of course.
It never crossed my mind that someone would try to
simultaneously connect both wired and wirelessly to the same subnet...

Thanks,
