我已使用 hostapd 和 dnsmasq 設定 ubuntu 伺服器(16.04TLS)作為存取點。對於網路連接,我使用內建 wifi 網路卡 (RTLINK),對於存取點 - wifi-usb 適配器。無需插入 Wifi-Usb,就有穩定的網路連線(我可以使用curl 上網)。插入 USB-Stick (Edimax EW-7811Un) 後,我可以將我的裝置連接到它(它廣播存取點),但隨後就不再有任何網路連線。
有什麼問題嗎?
網關是192.168.2.1

好的,Ipor Sircer 的評論是正確的,我在設定中使用了相同的 ip 範圍(對於 AP 連接和託管連接)。由於我的路由器有 192.168.2.1 gateway-ip,我會為 Hostapd-wifi-adapter 設定相同的範圍。在10.0.0.1設定hostapd的位址後問題解決
