XP Network Bridge Problem


J

Jered

I'm at my wits end, and can't seem to find anyone having the specific
same problem I'm having. If anyone can help, it would be HUGELY
appreciated.

Here's my setup:
I have a PC upstairs that is running XP Pro, connected to the internet
via a cable modem, running ICS, and connected to a Linksys WAP. I've
got multiple machines connecting to this WAP successfully (two laptops,
my PDA, and a Tivo). The WAP has a WEP key and MAC filtering.

Downstairs, I have three PCs connected to each other through an
Ethernet hub. One of the PCs (running XP Pro) also has a wireless
adapter (a Belkin USB adapter) that works just fine AS LONG AS I DON'T
BRIDGE IT WITH THE ETHERNET ADAPTER. As soon as I bridge it, although
the wireless appears to be connected the MAC Bridge Miniport does not
get an IP from ICS, and the machine loses connection to the internet.
I've put the MAC Bridge Miniport's MAC into the MAC filter list. I've
deleted and recreated the Bridge a dozen times. I turned off IEEE
Authentication on all connections, including the Bridge. I even put
the Ethernet card's MAC in there for good measure. No dice.

Yes, I turned on promiscuous mode on the Belkin wireless adapter, and
followed the Crawford article
(http://www.microsoft.com/windowsxp/using/networking/expert/crawford_02april22.mspx).

The worst part is, this once worked. It all stopped working when I
UNPLUGGED THE MACHINE. Reboots didn't kill it, but for some reason
losing all power (while I rearranged the room) did.

PLEASE HELP!!

Here are some things that might help:

1. Turn on promiscuous mode on the Ethernet adapter, too.
2. Temporarily disable MAC filtering.

If all else fails, I'd consider abandoning the network bridge and
getting a wireless gaming adapter to connect to the downstairs hub.
