前面有一篇 NanoPi – USB 網路卡 ( WiFi AP 應用 ) 真的要測試的同學應該都失敗了，因為文章內的網卡是多年前的產品使用 Ralink RT2573 晶片，雖然原生支援預設 hostapd nl80211 driver ，可是根本就買不到了。
友善之臂官網有賣 EDUP EP-N8508 USB WiFi ，使用的是 Realtek8188CUS 晶片，經過九九八十一難安裝過程如下

環境準備
|
1 2 |
# apt update # apt install git pkg-config libnl-3-dev libnl-genl-3-dev libssl-dev |

# vi /etc/network/interfaces allow-hotplug wlan0 auto wlan0 iface wlan0 inet static address 172.17.1.1 netmask 255.255.255.0 |
重新啟動網路讓設定生效
|
1 |
# systemctl restart NetworkManager |

安裝支援 RTL8188 的 hostapd 版本
|
1 2 3 4 5 |
# cd /home/pi # git clone https://github.com/lostincynicism/hostapd-rtl8188.git # cd hostapd-rtl8188/hostapd # make # make install |
驗證是否安裝完成

重新啟動 NetworkManager
|
1 |
# systemctl restart NetworkManager |
wlan0 已經脫離 NetworkManager 管理

hostapd.conf
|
1 2 3 4 5 6 7 8 9 |
vi /etc/hostapd.conf interface=wlan0 driver=nl80211 ssid=DAEGateway channel=8 macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=0 |
啟動程式測試
|

# hostapd -d /etc/hostapd.conf |
如果執行訊息沒有錯誤停止，那就是已經成功完成了
