thanks for your reply. What log file should I provide specifically?
The device is
Bus 003 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

I'm not sure, try looking in /var/log/syslog or dmesg
grep on terms like Network, network, Wireless, wireless as grep is case-sensitive.

Could you post the output of

and
ip link
?

Thank you. Finally I solved it by re-installing the rtl8188cus driver.
I downloaded the source code from AUR page, but it seems that is not compatible with my Linux 4.2.4-1-ARCH. After reading the discussion on the AUR page https://aur.archlinux.org/packages/8192cu-dkms/, I got the latest code from github https://github.com/dz0ny/rt8192cu. Compile and install it, reboot. And now the problem is solved.
Thank you for all your help.
One more question: will some update operation, e.g. pacman -Syu, which updates the kernel as well, affect some drivers? I mean, next time I update my system, would this problem come again? I used to work with debian and ubuntu and system update seems never to affect drivers or so.

each update can bring trouble so there will probably someday come an update which makes your drivers incompatible or something, but as long as the drivers are maintained as well the developers should keep it compatible with arch
