Adding a Wireless Connection to a Bridge

I'm trying to bridge my HPNA 2.0 card and my wireless pre-802.11n (Belkin
Pre-N) card using the Windows software bridge. They both work fine
independently, and the HPNA works in the bridge, but as soon as the wireless
card is added to the bridge, the wireless component doesn't seem to respond.
It says it's connected to the router, but I can't ping any wireless device.
Even if I add the wireless card to the bridge by itself, it becomes
unresponsive. I know a lot of you have wireless networks, so can somebody
tell me if the same thing happens to them or if there's a workaround? Thanks
so much.
