Beta 3- Intermittent network connection on MacbookPro?

[VTMac]

I've installed beta 3 with WinXP. I've tried both the RealTek and Parallels network driver. I am using Wifi, bridged. Both drivers intermittently drop and then come back. I can't seem to maintain a connection for more than 5-8 minutes. Then it drops for 60 seconds. Then 5-8 minutes. I'm also using Wifi on OSX. I've validate that both OSX and XP report different IPs / Mac Addresses, so I don't think it's a configuration problem.

Is anyone else having this issue?
Any ideas on how to get a stable connection?

Unfortunately, I have to use Wifi for both connections.

TIA

Ok, here is some more info. It appears that using bridged Wifi on the MBP, only OSX or WinXP can actually "own" the NIC at one time. What is happening is I have an IM going in OSX, and I'm trying to surf in IE. Everytime I get a message in OSX, IE stops working, until I open a cmd prompt and ping something on the local network. That seems to get "ownership" switched back to XP.

I hope this is a bug, and not by design, because this won't be real useful. As a model, I'd really like to see it work similar to Q.
