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:

  1. sudo lspci -v

  • Edit your question and show me 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.

@heynnema Thank you very much heynnema, but I have already fix the issue. I have modified this answers "No Wifi on Acer Aspire E5 573 on any Linux Platform" and "https://esc.sh/blog/wifi-issue-on-acer-laptops-running-linux-qualcomm-atheros-device-0042/" and it work for the moment. I didn't want to try before because I don't understand very well what the different files are for, but I've taken a risk and it seems that work.

My solution:

git clone https://github.com/kvalo/ath10k-firmware.git
sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/
sudo mv /lib/firmware/ath10k/QCA9377/hw1.0/CNSS.TF.1.0/firmware-5.bin_CNSS.TF.1.0-00267-QCATFSWPZ-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin

and again heynnema thank you very much for help me answering the question.
