I fear I can contribute more commiseration than assistance.  I have an
HP laptop with builtin Broadcom wireless.  I initially got CentOS 5
working with ndiswrapper, but had to change my access point from
shared to open authentication (WEP) and found that ndiswrapper fails
to authtenticate in the latter configuration.  The default bcm43xx
module handles the open authentication OK, but I experience a lot of
lost and duplicated packets -- experiments with ping show up to 30%
failure some of the time.  (I should update the HP ze5300 wiki page
with this info.)  I have to plug in to a wired net to do package

I have other wireless devices using the same AP with no problems, and
the same laptop performs well when booted into Windows, so this
appears to be a problem with the bcm43xx drivers.  I keep hoping that
each kernel update will improve the situation, but so far in vain.
