ubuntu 能够连接无线网 但是不能用浏览器上网

sudo ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device

rfkill list
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
2: brcmwl-0: Wireless LAN

求大家帮忙看看

为什么不用自带的NetworkManager？

用了NetworkManager 但是还是没有用 不知道不能上网是不是在Additional Driver 添加网卡驱动导致
