I have installed Lubuntu on an old Dell D600 laptop. Everything is working great except for the wireless Ethernet card.
"lspci -vnn -d 14e4:" reveals the following:
Broadcom Corporation BCM4309 802.11abg Wireless Network Controller [14e4:4324] (rev 02)
Somebody recently (Sept 5th) posted the answer for a card very similar to this (all the same except for the "rev 02" part) - and in their answer they stated something similar to "You have a 50% chance of having the other (rev 02) version of this wireless card - if it turns out you have that one, post back again for recommendations relevant to that".
Apparently the other question-asker did not have the "rev 02" version, as they did not post back again.
I'm hoping either the person posting that answer or somebody else here could post their recommendations for the "rev 02" version of this card.
