I have an old laptop,Dell Vostro 1510. I needed to install Kubuntu 14.04.3 on it. It doesn't recognize the wireless. I entered:
lspci -nn | grep 0280
in a terminal, as @chili555 suggested in question 547746 right here in ask ubuntu, and the outcome is:
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
Kubuntu 14.04 recognized wireless while live. I know there are some questions exactly about this on www.askubuntu.com but none have reached an end. Thank you
