USB-WIFI-RTL8188F不工作，未见报错
使用USB的wifi模组，型号是RTL8188F，编译驱动后放进去insmod，没有看见报错，有一些信息打出来，但ifconfig wlan0 up，提示ifconfig: SIOCGIFFLAGS: No such device
可能是什么问题？

Re: USB-WIFI-RTL8188F不工作，未见报错
twzy 说：
用这个命名 ls /sys/class/net/ 查看一下看看wlan0有没有被命名为其他网卡
$ ls /sys/class/net/ eth0 eth1 lo sit0 usb0 usb1 wlan1 wlx30eb1f1f3b8f wwan0 wwan1 # 出现wlan0和wlan1，其中wlan0被系统重命名为wlx30eb1f1f3b8f
已解决，USB驱动有问题。。。
没有设置为host模式
