Wireless Network bridged to hard wired lan

[alan]

I have a problem creating a network bridge so that I can
share my DSL connection to the internet with both a
wireless network and a hard wired LAN.

Both work independently when I configure internet
connection sharing. But when I bridge the two networks
the wireless connection stops working.

The problem seems to be with the bridge and the wireless
card, a D-Link Airplus Extreme DWL G520+. If I bridge the
two networks then only the wired network is able to
connect to the DSL Modem. Any ideas anyone?

The nic that connects to the DSL connection shouldn't be bridged with
anything.

If you also have a wired and a wireless nic on the ICS machine bridge these
2 together.

yes, it's a USB DSL Modem so I couldn't bridge it with
any of the nic's. I can create the bridge, add the first
nic that runs my hardwired lan and all works ok. if i
then add the wireless nic then the wireless card stops
working as though it doesn't exist. Yet both nic's will
work unbridged.

I contacted D-Link to see if there was an updated driver
but the driver is still v1.0.

Most wireless cards can not be bridged directly, because they are unable
to transmit frames with source MAC address not their own.
Because of this limitation, use only ICS.

Thanks Pavel A. this is probably the response that D-
Link should have given me. But what is ICS? (Is it
infrastructure something?) The answer to my problems
would be to go completely wireless and do away with the
bridge. There is no reason that I can not setup a three
way peer to peer network to share the internet connection
with two wireless network cards is there? That would mean
that I have to throw some more money at mr D-Link for not
helping

ICS stands for Internet Connection Sharing (see in Windows help).
It works the same way as "IP masquerading".
If you can get wireless Access Point with integrated ethernet router or even DSL modem, this would be best solution.

That's a known problem with some network adapters. Please see this
Microsoft Knowledge Base article for an explanation and a possible
solution:
