How to Install Broadcom Wireless card (BCM43XX)
I am currently using Ubuntu 10.10 on my laptop , the model of my wireless chip is broadcom BCM4312 802.11b/g LP-PHY .
I tried to activate the driver for the chip by going to
System -> Administration -> Additional Drivers and activated Broadcom STA wireless driver.
But the laptop can't detect any wireless signal still.
Do I have to do any additional work to make the chip work ? Or how can I test if there is physical damage to the chip itself?
