ThinkPad E530 ora 20 wireless Internet access problem, e530fedora
I have been using Linux ora Linux, but its built-in wireless NIC Driver seems to be a problem. Sometimes it can be connected and sometimes it cannot. I often cannot find the home wireless router. Because there is a network cable at home, I have never cared about it. In the past two days, I had nothing to worry about at home and finally completed the wireless NIC Driver.
First, determine the model of the wireless network card. The lspci command can be used. The output result is one line as follows.
. 0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)
First, go to the Broadcom official website to find the driver.

Http://www.broadcom.com/docs/linux_sta/hybrid-v35_64-nodebug-pcoem-6_30_223_248.tar.gz
Follow the instructions on the website to start compiling. Various errors are reported in the result. It is speechless and you are too lazy to modify the source code. You can only find other methods. Maybe the source of fedora 20 already has a compiled package.

Try to install it. restart the computer after installation, and the wireless network card is connected to the Internet.
It seems that yum should be the first choice for driving problems, which can save a lot of time.
