Deepin Linux doesn't show Wi-Fi?

I only installed Deepin 15.11 and I wanted to set up the WLAN but it does not show a single WLAN, so I have no Internet on my laptop. Can someone help me do not know me so well with Linux thanks.

There may be no drivers for your network hardware. Nobody can help you without any information.

It is best to open the terminal through the start menu and then enter the following commands:

1- ip link show or ip a (to check whether there's any Wi-Fi interface)

2- Check whether the WLAN card is recognized on the notebook with: iw dev

3- If this is not the case so no card installed, then determine what hardware it is: lspci -vv

Then please write what you think of problems
