为何浏览器无法访问网络资源了？

Question

一个台式电脑，安装了一个Usb 的无线网卡，家用无线路由器可以上网，这台电脑没有用有线连接路由器，我准备借助无线网卡上网。

硬件信息
lsusb 
Bus 001 Device 007: ID 0cf3:9271 Qualcomm Atheros Communications AR9271 802.11n

sudo iwconfig | rg ESSID
wlx001a8c3008b1  IEEE 802.11  ESSID:off/any  

上网设置

wlan="wlxe0e1a99f3bc6"
sudo ip link set dev $wlan up
sudo iwlist $wlan scan | grep ESSID
                    ESSID:"Xiaomi_9113"
wpa_passphrase myhost xxxx | sudo tee -a /etc/wpa_supplicant/wpa_supplicant.conf
sudo wpa_supplicant -c /etc/wpa_supplicant/wpa_supplicant.conf -i $wlan

输出如下

Successfully initialized wpa_supplicant
nl80211: kernel reports: Match already configured

wlx001a8c3008b1: CTRL-EVENT-CONNECTED - Connection to 3c:cd:57:58:91:14 completed [id=1 id_str=]

应该是连上了吧，我打开chrome,输入baidu.com

Try:

Checking the network cables, modem and router
Reconnecting to Wi-Fi
DNS_PROBE_FINISHED_NO_INTERNET

如何解决？
