最近回家，學習許久未用的linux，之前也是在培訓的時候用的是 Ubuntu ，這次回家查了下 fedora 最適合開發人員使用，所以就裝了個試試。剛開始只能撥號上網，經過三天時間的各種搜索查找終于解決了無線上網問題，感覺挺開心！現在大致寫出來分享以下，希望可以幫助對fedora有興趣的同學們！

• 設備 筆記本（硬件型號最好是主流的，兼容性問題很難解決） + 有根可以上網的網線
• 步驟

1. 在 fedora 官網 https://getfedora.org/ 上下載 最新版 live 鏡像，選擇 WORKSTATION (版本選擇里面很詳細，個人就選這個)，電腦內存 >=4G 的裝 64 位的系統；
2. 搜索下載 Poweriso 軟件，按照步驟去制作 U 盤啟動盤，然后開機按 F12 進入 bios 選擇 USB 啟動……具體系統安裝比較簡單，就不說了，注意下選擇手動分區；
3. 安裝好系統后查好網線設置撥號上網和無線上網：

1. 首先設置撥號上網帳號，密碼和服務器等。之后使用pppoe-start即可上網，具體步驟如下：

   [root@localhost~]# pppoe-setup ---------------這里開始安裝PPPOE

   Welcometo the PPPoE client setup. First, I will run some checks on

   yoursystem to make sure the PPPoE client is installed PRoperly...

   LOGINNAME

   Enteryour Login Name (default root): 081842162@ahut---------------這里是上網的帳號

   INTERFACE

   Enterthe Ethernet interface connected to the PPPoE modem

   ForSolaris, this is likely to be something like /dev/hme0.

   ForLinux, it will be ethX, where 'X' is a number.

   (defaulteth0): ---------------這里按回車鍵（我這里的是enp4s0）

   Doyou want the link to come up on demand, or stay up continuously?

   Ifyou want it to come up on demand, enter the idle time in seconds

   afterwhich the link should be dropped. If you want the link to

   stayup permanently, enter 'no' (two letters, lower-case.)

   NOTE:Demand-activated links do not interact well with dynamic IP

   addresses.You may have some problems with demand-activated links.

   Enterthe demand value (default no): ---------------這里按回車鍵

   DNS

   Pleaseenter the IP address of your ISP's primary DNS server.

   Ifyour ISP claims that 'the server will provide dynamic DNS addresses',

   enter'server' (all lower-case) here.

   Ifyou just press enter, I will assume you know what you are

   doingand not modify your DNS setup.

   Enterthe DNS information here: ---------------這里鍵入server也就是自動獲得DNS

   PASSWord

   Pleaseenter your Password: ---------------這里鍵入上網撥號密碼

   Pleasere-enter your Password: ---------------這里鍵入上網撥號密碼

   USERCTRL

   Pleaseenter 'yes' (three letters, lower-case.) if you want to allow

   normaluser to start or stop DSL connection (default yes):---------------這里鍵入 yes

   FIREWALLING

   Pleasechoose the firewall rules to use. Note that these rules are

   verybasic. You are strongly encouraged to use a more sophisticated

   firewallsetup; however, these will provide basic security. If you

   arerunning any servers on your machine, you must choose 'NONE' and

   setup firewalling yourself. Otherwise, the firewall rules will deny

   accessto all standard servers like Web, e-mail, ftp, etc. If you

   areusing SSH, the rules will block outgoing SSH connections which

   allocatea privileged source port.

   Thefirewall choices are:

   0- NONE: This script will not set any firewall rules. You areresponsible

   forensuring the security of your machine. You are STRONGLY

   recommendedto use some kind of firewall rules.

   1- STANDALONE: Appropriate for a basic stand-alone web-surfingworkstation

   2- MASQUERADE: Appropriate for a machine acting as an Internet gateway

   fora LAN

   Choosea type of firewall (0-2): 0 ---------------這里鍵入0

   Startthis connection at boot time

   Doyou want to start this connection at boot time?

   Pleaseenter no or yes (default no):y ---------------這里鍵入y

   **Summary of what you entered **

   EthernetInterface: eth0

   Username: xy170638010214

   Activate-on-demand:No

   DNSaddresses: Supplied by ISP's server

   Firewalling:NONE

   UserControl: yes

   Acceptthese settings and adjust configuration files (y/n)? y---------------這里鍵入 y

   Adjusting/etc/sysconfig/network-scripts/ifcfg-ppp0

   Adjusting/etc/ppp/chap-secrets and /etc/ppp/pap-secrets

   (Butfirst backing it up to /etc/ppp/chap-secrets.bak)

   (Butfirst backing it up to /etc/ppp/pap-secrets.bak)

   Congratulations,it should be all set up!

   Type'/sbin/ifup ppp0' to bring up your xDSL link and '/sbin/ifdown ppp0'

   tobring it down.

   Type'/sbin/pppoe-status /etc/sysconfig/network-scripts/ifcfg-ppp0'

   tosee the link status.

   [root@localhost~]# pppoe-start ---------------激活PPPOE設備，成功后會自動返回

   [root@localhost~]# pppoe-status ---------------查看PPPOE狀態

　　　　　　2.設置無線上網

　　　　　　　設置好包好連接后，可以先 sudo yum update 更新系統，查看無線網卡型號，在終端輸入 lspci |grep -i network

　　　　　　　　[lsf@lsf ~]$ lspci |grep -i network　　　　　　　　03:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01) 　　　　　　　　這個型號的網卡我找了好多帖子，但是未果，后來搜索該網卡兼容性的時候發現了一個帖子完美解決了這個問題，方法如下：

　　　　　　　　　　用root直接　　　　　　　　　　yumlocalinstall --nogpgcheckhttp://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm

　　　　　　　　　　http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

　　　　　　　　　　　 之后直接yuminstall kmod-wl

　　　　　　　　　　　 最后reboot。

　　　　　　　　　　　之后可愛的NetworkManager里出現了wifi...

好了大致就這樣咯！最后看看我的桌面吧！
