Re-pit the little buddy a computer for CentOS practice and server use, hahaha

Installed CentOS 7 After discovering that the wireless card can not read, no driver, Nic is Broadcom╮ (╯_╰) ╭

1. First determine if the NIC is the pit-daddy type Broadcom:

/sbin/lspci | grep Broadcom

As a result, yes:

[Email protected] ~]#/sbin/lspci | grep broadcom04:00.0 Network controller:broadcom Corporation BCM4312 802.11b/G lp-phy (rev.) 06:00.0 Ethernet Controller : Broadcom Corporation netlink bcm5906m Fast Ethernet PCI Express (rev 02)

  

2. Need to get the network card driver down, and then compile their own, so you must first Ann this thing:

sudo yum install kernel-headers kernel-devel gcc

3. View the number of system bits (if you know you can skip this step):

Getconf Long_bit

(the int type and long type are generally 4 bytes in a 32-bit system, and the int type in the 64-bit system is still 4 bytes, but long has become a 8-byte inux "getconf word_bit" is available in the system and
"Getconf long_bit" gets the number of digits for word and LONG. 64-bit systems should be 32 and 64, respectively. )

Next, download the http://www.broadcom.com/support/802.11/linux_sta.php driver here.

You can also use wget: This is the address of wget:

32-bit: http://www.broadcom.com/docs/linux_sta/hybrid-v35-nodebug-pcoem-6_30_223_248.tar.gz

64-bit: http://www.broadcom.com/docs/linux_sta/hybrid-v35_64-nodebug-pcoem-6_30_223_248.tar.gz

4. Installation
