I have installed arch in an another computer smoothly,but with this laptop things got weired. The device is a usb wirelesscard, should that be a question?
Any suggestion is needed, thanks in advance!

What is the device? What is the driver?
Not an Installation issue, moving to NC...

The device is Wavlink WN687N1 wireless usbcard with Realtek RTL8188CU chipset.
I don't know what the driver is ,maybe it's included in the kernel?

Well you clearly have the firmware.
What does this say:
ip r
EDIT: Hold on, is that the correct firmware?
Post the output of:
lsmod|grep rtl

So you have no IP addresses assigned.
You could try assigning them statically:
https://wiki.archlinux.org/index.php/Ne … assignment
If that doesn't work, check the product ID & vendor ID using:
# update-usbids
# lsusb
Then check if the device should be using the rtl8192cu module.

You are right, it's an IP problem,turns out the router was not properly configured. I was misleading in the first place.
Thanks a lot, I will do some reading and gain more concepts about connect process.
