I dual booted my Laptop Acer Aspire E5-573G with Windows 10 and Ubuntu 18.04 and since the first day the WIFI is connecting and disconnecting frequently. I have been searching in others questions but I do not know to fix it on my own.
From what I have learned from the other questions I leave here the results of the following commands:
- sudo lspci -v
