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

Thanks to all the people that is going to read this post and help me (and to others with the same/similar problem).
iwlist wlan0 scan | grep -i cell -A5
, changing wlan0 to your appropriate wireless device. What wireless network do you normally use? Post the output to paste.ubuntu.com and give me the URL. Start comments to me with @heynnema or I may miss them.
