More information please.

1. Is your "latest b43legacy" from wireless-testing, 2.6.26-rc9, or what?

2. What BCM43xx card are you using?

3. What wireless router are you using?

Using the wireless-testing git tree with a BCM4306/2 and working with a Linksys 
WRT54GL router with standard firmware, my statistics for the ping -c 100 
192.168.1.1 command are 0% packet loss with average rtt of 2.919 ms.
