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

# 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
|

# systemctl restart NetworkManager |

# 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
