Wireless doesn't use Internet when Ethernet connected at same time

[eljainc]

Hello,

I have an interesting situation. The wireless network connection
connects to the Internet with no problems as long as the wired
Ethernet is not plugged into the PC. The wired ethernet has a fixed/
private IP address of 172.16.1.203. If both are connected at the same
time, I no longer get internet connectivity. I have reviewed the
advanced settings with the order of the networks (Advanced Settings)
and the wireless network is on top of the Ethernet network so it
should get precedence. However the problem still occurs. How can I
fix this?

Thanks
Mike

While in the Advanced Settings did you also check the "Provider Order"
(TAB) ? Does the Wired Ethernet used by itself give you web connectivity ?

What's the reason you need both wireless and wired connection?

If both are connected at the same
time, I no longer get internet connectivity.

Is there default gateway on the wired NIC? Is there internet connection on
the wired NIC?

That's probably both NICs metric are set to Automatic. If you must use both
NICs simultaneously, try setting your WiFi NIC metric to 10 and wired NIC
metric to 20 (in TCP/IP Advanced settings).

What happens when you have two internet connections on the same computer is
the OS will detect the fastest path and use that.

That's exactly what I suspect. It auto picks wired connection (100Mbps or
1Gbps) and there's a good chance that there's no internet connection on the
wired connection. Setting metric weight might help.

I tried manually adjusting the metrics for each. I assigned 10 to the
wireless and 20 to the local area connection. However only the
wireless connection works now. The wired connection does not have
internet on it. It is connected to another computer through a hub/
switch.

The routing is governed by destination IP address and the Routing
Table. What would really be helpful to us is if you posted the output
of a "route print" or "netstat -rn" command from a Command window.
