my PC's integrated wireless doesn't work

My asus PC seem to not recognize the wireless card since my last boot. It worked in the past for a short period of time but then started to be instable andthen doesn't seem to work at all.
My PC is asus x540la
My AP is huawei Name=Home Gateway Model=HG532e
I installed ubuntu 19 on a hard disk
Unfortunatly, my PC doesn't recognize the wireless so lspci -nn give me this output
