BCM4313 Wireless Adaptor Error

Since many time, I was facing an issue of wireless network adapter. My wireless was working perfectly.

The error appeared at the boot time.

b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 10, Type 8 (LCN), Revision 1)

b43 firmware doesn't support BCM4313 wireless network adapter

root@nirav:~# lspci | grep -i network
05:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)

blacklist "b43 module"

root@nirav:~# vim /etc/modprobe.d/blacklist.conf

at the end of file

blacklist b43

root@nirav:~# rmmod b43

root@nirav:~# lsmod | grep b43

I restarted the system to ensure the b43 module is not loaded.

root@nirav:~# reboot
