The Local Wireless NIC driver cannot be installed, which is inconvenient. After reading a lot of information, Dell and Broadcom do not provide drivers for Linux. The existing drive is b43, refer to http://linuxwireless.org/en/users/Drivers/b43

 

However, the instructions are not in English, and the installation method above finally encountered a problem. Khan ~~~~~~~~ It's just not done .............

 

That's all. I carefully checked my Nic chip type:

The chip type is bcm4312 802.11b/g.

bcm4312

A/B/g

14e4: 4312

Not Supported-ID is duplicated

Bcm4312

B/g

B43

 

 

My Nic is B/g, but a/B/g is supported. I don't know if my understanding is correct ~~~~ All of them are of the 4312 model, so complicated .....

 

At last, I accidentally found that my wireless network card was actually equipped with a driver, but it was not correct. Search for Broadcom in the new software package manager. It is found that there are four items in total and two items have been installed.

Remove the two items and then select

B43-fwcutter

Broadcom 43xx firmware Extraction Tool

Bcmwl-kernel-Source

Broadcom 802.11 Linux sta wireless driver source

 

These two items. I don't know if I can omit this item. After the restart, the NIC will be ready.

 

Note:

Bcmwl-kernel-Source

Description:


These packages contain the Broadcom 802.11 Linux sta Wireless Driver for use.

Broadcom is based on bcm4311, bcm4312, bcm4321, and bcm4322.

Hardware.

There is also a Broadcom bcm5700 Ethernet driver module usedSource code
I guess bcm5700 will install this, but I can't try it.

 

 

The wireless drive provided by this project is much more convenient. You can go to the sixth floor in one breath ~~~~
