我正在使用 Ubuntu 20.04.6，并且一直经历着间歇性的 Wi-Fi 断开连接，期间我的 Wi-Fi 图标变成了一个问号。 在 Wi-Fi 自动重新连接之前，我能够获取到以下所有信息： - `ifconfig -a` 的输出： ``` eno1: flags=4099 mtu 1500 ether ec:8e:b5:45:a7:27 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 96567 bytes 8206625 (8.2 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 96567 bytes 8206625 (8.2 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 wlo1: flags=4163 mtu 1500 inet 192.168.0.20 netmask 255.255.255.0 broadcast 192.168.0.255 inet6 2606:a800:cf85:1a00:76e6:5d29:86fc:8d7e prefixlen 64 scopeid 0x0 inet6 fe80::20fc:fa07:8117:1c33 prefixlen 64 scopeid 0x20 inet6 2606:a800:cf85:1a00:c56d:f38c:137a:80e1 prefixlen 64 scopeid 0x0 ether 40:49:0f:48:d6:94 txqueuelen 1000 (Ethernet) RX packets 1558979 bytes 1007454192 (1.0 GB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 918856 bytes 168900180 (168.9 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ``` - `ping 192.168.0.1`（这是我路由器的 IP）的输出： ``` PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

    从您提供的`iwconfig`输出片段来看： ``` wlo1 IEEE 802.11 ESSID:"patawad" Mode:Managed Frequency:2.437 GHz Access Point: C0:C5:22:4C:9E:D0 Bit Rate=54 Mb/s Tx-Power=20 dBm ``` 您似乎正在使用2.4GHz，54Mb/s的网络，这相当于IEEE 802.11g-2003（WiFi 3）标准。 这个标准已经有20年的历史了，出于安全和性能的考虑，我强烈建议您将WiFi接入点升级至至少WiFi 5或6，这将更适合现代系统，包括Ubuntu。
