After some time the disconnect happened to me even when compiz was off,
so compiz may simply speed disconnects up but does not cause it
** Description changed:
network connection drops regularly when using
network controller : Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
and
- compiz visual effects
- and
- more drops under heavy network load
+ under heavy network load
original description :

Binary package hint: network-manager
Network manager drops wired connections repeatedly. It seems to be
correlated with accessing servers. Pages with lots of images (e.g.
www.dilbert.com) seem to trigger the bug more readily than simple text
only pages.
The connection is immediately picked up again using DHCP.
This is using Intrepid beta.
