Unstable wifi/Connection drops with Qualcomm QCA9377 on Ubuntu 18.04

So I have dualboot on my Acer Aspire with Linux Lite XFCE(Ubuntu) and Windows 10. Network Controller: Qualcomm Atheros QCA9377 802.11ac A while ago I started having issues with Wifi connection regularly dropping when I was on Linux. Pinging my router (192.168.1.1) gave no result, but the Wifi icon identified that I was still connected. This was happening once in every 15 minutes or so and the fix was reconnecting or waiting a couple of minutes. Obviously, this is really annoying as I can't really work on my laptop because of this. Under Windows Wifi works fine, no issues like that. I found [this issue](https://askubuntu.com/questions/1125262/qca9377-unstable-wifi-connection-on-ubuntu-16-04) . I don't have access to the router I'm using and I'm sure there's a Linux solution because the issue doesn't exist on Windows. Here's the wireless-info script result https://pastebin.com/Z4mZjaNd [This question](https://unix.stackexchange.com/questions/525272) 's solution did not work for me (changing router's bandwidth from auto to 20MHz)
