well, a little story first -
- I disabled/removed the STA driver then
- over the weekend a belkin N300 usb wifi dongle plugged in and tried;
- I fiddled with dkms and tried to get the realtek module loaded; net results
same as with the internal broadcom (the realtek module was created and
installed with no errors); brief conn'n established , the dongle light was
coming on - as with broadcom then out of the blue disconnected and dongle
light disappeared.
- then in additional drivers the belkin/realtek driver removed too.
- used ndiswrapper and xp drivers; net result even worse than the first two -
as soon as the command connect issued the desktop disappeared , dumped to a
console with enable trace last line and a hard pc lock.
so I decided for a new oneiric install with the N300 usb wifi present.
alernate CD install went ok. after first boot

big diff from first post #4. no eth1 - now wlan0; no wl but (from
lsmod)

conclusion : broadcom internal wifi works flawless; solid good steady
conn'n. why this time and not on first install ? v hard for me to tell.
I used the same install media, reformatted the same size part sda7 same
swap - totally puzzled.
thanks to all. I will not try any other kernels - if it ain't broken
don't fix it. thank you Joseph.
