Has anyone else seen this type of performance hit caused by the TAP driver?

I don't know if this qualifies as a performance hit, but with the TAP driver
my entire external network goes dead. I've spent many hours trying all kinds
of stuff and finally gave up. I also have a Broadcom B57 nic, but am using
the native driver.

You don't have it tied to a wireless as well do you?  If I connect to wireless it knocks out my whole network, wired and wireless.
