I get much stable connection with external wifi card and I'd expect to get
similar on Broadcom card.
This is ping got using external Belkin USB wifi

This is happening all the time and over same time it get even worse up
to seconds ping, basically making the inbuilt card useless.
product: BCM4322 802.11a/b/g/n Wireless LAN Controller
this is the original driver from ubuntu installation
configuration: broadcast=yes driver=wl0 driverversion=5.60.48.36
ip=192.168.11.5 latency=0 multicast=yes wireless=IEEE 802.11abgn
I also downloaded, built and installed latest driver from broadcom which does
not resolve the problem and works exactly same way
configuration: broadcast=yes driver=wl0 driverversion=5.60.246.6 latency=0
multicast=yes wireless=IEEE 802.11abgn
I've tried to disable power management as some people on boards say may
help, does not in my case.
To confirm that the problem is this card I tried 2 different access points,
with PSK2 or WEP with external and internal wifi and tried also different
computers with ubuntu 10.10 installed or windows 7.
In all cases, only and always problematic card was the inbuilt Broadcom card.
Please help, its quite bad to carry the USB wifi with me all the time
