Cabled and Wireless connection on laptop without setup ?

[Glenn]

Hi,

I have a laptop with both cabled and wireless network adaptors.
The laptop runs win 2000 pro. The network is a small home network with
Linksys BEFS11W wireless router.

I can't get the setup right to connect via Wireless when the cable is
out, without having to disable the cabled Network connection.

Both cabled & wireless Connections have a static IP on the same subnet
(only one available due to linksys)
Cabled: 192.168.1.10; Wireless: 192.168.1.25

The other settings are the same, except Interface Metric:
cabled = 1; Wireless = 50

When both connections are enabled, the cabled network/route is
prioritized as it should be (quicker)

My problem starts when I disconnect the LAN cable. Windows confirms the
cable is disconnected, but still try to go the cabled route; resulting
in network connection loss.
( route print shows routes for both adaptors)

Only if I disable the cable network connection in control panel, the
wireless route is taken and yields a working connection.
( route print shows routes only for wireless adaptor)

How must I configure my machine to get the cabled & wireless adaptors to
live together without manually adjusting the settings each time
connectivity changes?

best regards
glenn

Hello there,

you can have a default gateway for each NIC adapter in Windows 2000 Pro but there is only a single active default route in the IP route table.
When you disconnect the the NIC with the active default route, it does not remove its TCP/IP configuration from the TCP/IP stack as you can confirm when
you run 'route print' from a command prompt.
Have you tried adding static routes to the routing table?
You may want to try enabling "EnableDeadGWDetect" for the TCP/IP stack on the client.

Setting the registry 'EnableDeadGWDetect' to 0 (disabled ?!) did the
trick. Disconnect the cable, wait a few moments and the traffic flows
thru the other connection. Great!

It was, as you indicated, the gateway route holding on to the
disconnected interface as seen in following data.
I tried to add/change a static route. Bu as route add/delete/change
refuses 255.255.255.255, I failed. Perhaps you can show me my error.

Already thanks for the solution
