I use xfce 4.10 and wicd.
What is the matter?
Thanks

waterloo2005,
udev is the matter. | Code: | | [ 8.694189] systemd-udevd[363]: renamed network interface wlan0 to wlp0s29u1u3u4 |
udev has renamed your wlan0 to wlp0s29u1u3u4. Worse, its name will depend on the USB port that you plug the WiFi into.
Add net.ifnames=0 to the kernel line in grub.conf to keep the old kernel allocated names.
If you use wired networking now, your wired interface will revert to eth0 too.

Thanks first.
In wicd, I can not find any wireless connection point. I think the drive of usb wireless card does not take effect.
How to do with it ?

waterloo2005,
Its possible for your interface to exist but not work. Please post your dmesg output.
You can put it into a file with then post the file dmesg.txt.
If you are using wired networking then wgetpaste is your friend.

ath9k_htc is module for usb wireless card. ath9k is module for pci wireless card which works ok.
This is dmesg after I detach and attach usb wireless card .

waterloo2005,
Look at the very last line in your dmesg post.
Please try the net.ifnames=0 fix I suggested before.
The good news is that there are no messages about firmware not being loaded, so I would expect your inteface to work.

After using net.ifnames=0, pci wireless card does not work , too. In 'ifconfig' command , only find 'lo'.
Thanks
