(Windows default) The priority connection that used to access Internet.

[Rex]

Dear Sir/Madam,
I have a question and hope to get help from anyone.

What is the priority connection (Windows default) that
used to access Internet when "dial-up (56Kbps)", "LAN
(10/100Mbps)" and "WLAN (2/6/11Mbps) are available.

I did a simple test, the following is the result that I
get and I am not so sure is that correct or not.

Test 1:
1. I connect the 3 connections (WWAN-GPRS, LAN, WLAN),
sequency is not important.
2. Ping www.yahoo.com.
3. It will use WWAN-GPRS (115.2Kbps) to access Internet.

Test 2:
1. If i connect the 2 connections (LAN, WLAN), sequency is
not important.
2. Ping www.yahoo.com.
3. It will use LAN (10Mbps or 100Mbps) to access Internet.

I hope someone could verify for the issue above for me.

Thank you.

Warm Regards,
Rex

A dial-up connection takes priority. Windows assumes that when you
connect to the Internet through a dial-up connection, you want to use
that connection instead of other ones.

Here's how it works:

1. Each Internet connection has an associated default route in the
TCP/IP route table.

2. Each default route has an associated value called "metric". The
value is in the range 1-9999.

3. When there's more than one default route, Windows uses the one that
has the lowest metric.

4. When a dial-up connection is established, its metric is set to 1,
and the metric of every other connection is increased by 1. That
guarantees that the dial-up connection's metric is the lowest.

5. When a dial-up connection is disconnected, the metric value of
every other connection is decreased by 1.
