wifi介面：不可用“Realtek RTL8723BE” |Debian 10

我最近在華碩筆記型電腦上安裝了 Debian 10，但沒有連接無線網路。這是命令 nmcli 的輸出：

enp2s0f2: connected to Wired connection 1
   "Realtek RTL810xE"
   ethernet (r8169), MAC Adress, hw, mtu 1500
   ip4 default

lo: unmanaged
   "lo"
   loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536

DNS configuration:
   servers: 192.168.1.1
   interface: enp2s0f2

通過更新和安裝 realtek 韌體解決了這個問題。以下是命令：

apt-get update && apt-get install firmware-realtek
